Global Configuration Mode Commands
Use global configuration mode for setting, viewing, and testing configuration of WAAS software features for the entire device. To enter this mode, enter the configure command from privileged EXEC mode. The prompt for global configuration mode consists of the hostname of the WAE followed by (config) and the pound sign (#). You must be in global configuration mode to enter global configuration commands.
WAE# configure
WAE(config)#
Commands entered in global configuration mode update the running configuration file as soon as they are entered. These changes are not saved into the startup configuration file until you enter the copy running-config startup-config EXEC mode command. Once the configuration is saved, it is maintained across WAE reboots.
You also can use global configuration mode to enter specific configuration modes. From global configuration mode you can enter the interface configuration mode, standard ACL configuration mode, or the extended ACL configuration mode.
To exit global configuration mode and return to privileged-level EXEC mode, use either the exit or end global configuration command:
WAE(config)# exit
WAE#
(config) aaa accounting
To configure AAA accounting on a WAAS device, use the aaa accounting global configuration command. To unconfigure AAA, use the no form of this command.
aaa accounting cms enable tacacs+
no aaa accounting cms enable tacacs+
aaa accounting commands {0 | 15} default {start-stop | stop-only | wait-start} tacacs
no aaa accounting commands {0 | 15} default {start-stop | stop-only | wait-start} tacacs

System start-stop TACACS+
The following example shows that the WAAS device is set to record all user EXEC sessions. The command also specifies that a stop accounting notice should be sent to the TACACS+ server at the end of the session.
WAE(config)# aaa accounting exec default stop-only tacacs
The following example shows that the WAAS device is set to record all CLI commands executed by a normal user. The command also specifies that a stop accounting notice should be sent to the TACACS+ server at the end of each CLI command executed by a normal user.
WAE(config)# aaa accounting commands 0 default stop-only tacacs
The following example shows that the WAAS device is set to record all CLI commands executed by an administrative user. The command also specifies that a start accounting notice should be sent to the TACACS+ server at the beginning of the process and a stop accounting notice at the end of the process. The CLI command executed by the administrative user does not proceed until the start accounting notice has been acknowledged.
WAE(config)# aaa accounting commands 15 default wait-start tacacs
The following example shows the EXEC shell accounting report that is available on the TACACS+ server:

task_id=3511 timezone=PST service=shell priv-lvl=0 cmd=logging console enable
In addition to command accounting, the WAAS device records any executed CLI command in the system log (syslog.txt). The message format is as follows:
ce_syslog(LOG_INFO, CESM_PARSER, PARSER_ALL, CESM_350232,
"CLI_LOG %s: %s \n", __FUNCTION__, pd->command_line);
Related Commands
(config) aaa authorization commands
To authorize commands issued through the CLI by a user on a WAAS device, use the aaa authorization commands global configuration command. To disable command authorization, use the no form of this command.
aaa authorization commands level default tacacs+
no aaa authorization commands level default tacacs+
Syntax Description
Defaults
AAA command authorization is disabled by default.
Command Modes
global configuration
Device Modes
application-accelerator
central-manager
Usage Guidelines
Command authorization enforces authorization through an external AAA server for each command executed by the user. All commands executed by a CLI user are authorized before they are executed.
When command authorization is configured for level 0, only EXEC commands are authorized, regardless of user level (normal or super).
When command authorization is configured for level 15, EXEC and global configuration commands are authorized, regardless of user level (normal or super).
Once it is configured, command authorization configuration is displayed in the running config. When the running config is copied to the startup config, command authorization is configured as the last config so that during the reload, the startup config need not be authorized.
Only commands executed through the CLI interface are subject to command authorization.
Examples
The following example shows how to configure command authorization for level 15 (authorization for both EXEC and global configuration commands) on the WAAS device:
WAE(config)# aaa authorization commands 15 default tacacs+
Related Commands
(config) accelerator cifs
To enable the CIFS application accelerator, use the accelerator cifs global configuration command. To disable the CIFS application accelerator, use the no form of this command.
accelerator cifs {[double-byte-unicode] | enable | eviction-monitor {cumulative-time mins | duration mins | enable} | dynamic-share share | clear cache | cache server-rename oldname newname | exception {coredump | debug | no-coredump}}
no accelerator cifs {[double-byte-unicode] | enable | eviction-monitor {cumulative-time mins | duration mins | enable} | dynamic-share share | clear cache | cache server-rename oldname newname | exception {coredump | debug | no-coredump}}
Syntax Description
Defaults
The CIFS accelerator is enabled by default and will start automatically if the Enterprise license is installed. The default exception action is coredump.
Command Modes
global configuration
Device Modes
application-accelerator
Usage Guidelines
Use the accelerator cifs enable command to enable the acceleration of CIFS traffic with the transparent CIFS accelerator (not the legacy mode of acceleration).
The CIFS application accelerator requires that the WINS server be configured. Use the windows-domain wins-server global configuration command to configure the WINS server.
Use the accelerator cifs eviction-monitor command to enable and monitor the aggressive cache eviction for a cumulative time or duration.
To configure prepositioning directives, use the accelerator cifs preposition global configuration command.
Use the accelerator cifs dynamic-share command to define a dynamic share, which allows multiple users to access the same share but then be automatically mapped to a different directory based on the user's credentials. Defining a dynamic share allows each user to see a different view of the share, and allows the operation of Access Based Enumeration, if configured on Windows Server.
Note We recommend that you use the WAAS Central Manager GUI to configure dynamic shares because the dynamic share CLI configuration can be overwritten by the Central Manager. For more information, see the "Creating Dynamic Shares" section in the Cisco Wide Area Application Services Configuration Guide.
Use the accelerator cifs cache server-rename command to rename the data in the cache if the name of a file server changed and you do not want to lose the cached data for the server. The renaming applies to prepositioned files and files cached on demand.
Note Do not specify the name of another existing cached file server as the new name. If you do specify an existing name as the new name, the cached contents of this file server are overwritten with the cached contents of the file server you are renaming.
Examples
The following example shows how to enable the CIFS application accelerator:
WAE(config)# accelerator cifs enable
Related Commands
(config) accelerator cifs preposition
To configure a CIFS application accelerator preposition directive, use the accelerator cifs preposition global configuration command. To disable the application accelerator, use the no form of this command.
accelerator cifs preposition [remove] directive_id
no accelerator cifs preposition [remove] directive_id
Syntax Description
remove |
(Optional) Deletes a preposition directive. |
directive_id |
ID of an existing preposition directive that you want to change or delete, or a new directive that you want to create. |
Defaults
No default behavior or values.
Command Modes
global configuration
Device Modes
application-accelerator
Usage Guidelines
Use the accelerator cifs preposition command to create and edit preposition directives to be used with the transparent CIFS accelerator. A preposition directive defines a set of files that are to be prepositioned on the WAE device.
The accelerator cifs preposition command invokes the preposition configuration submode. For details on the commands available in this submode to configure a preposition directive, see the "Preposition Configuration Mode Commands" section.
Note We recommend that you use the WAAS Central Manager GUI to configure preposition directives. For more information, see the "Creating a Preposition Directive" section in the Cisco Wide Area Application Services Configuration Guide.
Note If you create a preposition directive from the CLI before the secure store on the WAE is initialized, you must wait at least two datafeed poll cycles (10 minutes by default) before initializing the secure store; otherwise, the preposition directive will not propagate to the Central Manager because the credentials will not be able to be decrypted on the WAE.
Examples
The following example shows how to create a new CIFS preposition directive with ID 3:
WAE(config)# accelerator cifs preposition 3
WAE(config-preposition)
Related Commands
(config) accelerator epm
To enable the Endpoint Mapper (EPM) application accelerator, use the accelerator epm global configuration command. To disable the EPM application accelerator, use the no form of this command.
accelerator epm {enable | exception {coredump | debug | no-coredump}}
no accelerator epm {enable | exception {coredump | debug | no-coredump}}
Syntax Description
Defaults
The EPM accelerator is enabled by default and will start automatically if the Enterprise license is installed. The default exception action is coredump.
Command Modes
global configuration
Device Modes
application-accelerator
Usage Guidelines
Use the accelerator epm enable command to enable the acceleration of EPM traffic. The EPM accelerator must be enabled for the MAPI accelerator to operate.
Examples
The following example shows how to enable the EPM application accelerator:
WAE(config)# accelerator epm enable
Related Commands
(config) accelerator http
To enable the HTTP application accelerator, use the accelerator http global configuration command. To disable the HTTP application accelerator, use the no form of this command.
accelerator http {enable | dre-hints {access-list acl | enable}| exception {coredump | debug | no-coredump} | metadatacache {access-list acl | enable | conditional-response enable | filter-extension extension-list | redirect-response enable | request-ignore-no-cache enable | response-ignore-no-cache enable| unauthorized-response enable | max-age seconds | min-age seconds | filter-extension extension-list | https {access-list acl | enable}} | sharepoint-opt prefetch enable | suppress-server-encoding {access-list acl | enable}}

Syntax Description
enable |
(Optional) Enables the HTTP application accelerator. |
dre-hints |
Configures HTTP and HTTPS DRE hints feature. |
access-list acl |
Configures the HTTP AO feature subnet to associate an access list to an HTTP AO feature. acl refers to an ACL that can be created by the ip access-list CLI. See (config) ip access-list. |
exception |
(Optional) Configures the action to be taken if an exception occurs. |
coredump |
Writes a core file (default). |
debug |
Hangs the system until it is explicitly restarted. |
no-coredump |
Restarts the accelerator and does not write a core file. |
metadatacache |
(Optional) Configures metadata caching. |
enable |
(Optional) Enables metadata caching. |
conditional-response enable |
(Optional) Enables caching of HTTP 304 messages. |
redirect-response enable |
(Optional) Enables caching of HTTP 301 messages. |
request-ignore-no-cache enable |
Configures the metadata cache to ignore cache-control on requests. |
response-ignore-no-cache enable |
Configures the metadata cache to ignore cache-control on responses. |
unauthorized-response enable |
(Optional) Enables caching of HTTP 401 messages. |
max-age seconds |
(Optional) Specifies the maximum number of seconds to retain HTTP header information in the cache. The default is 86400 seconds (24 hours). Valid time periods range from 5-2592000 seconds (30 days). |
min-age seconds |
(Optional) Specifies the minimum number of seconds to retain HTTP header information in the cache. The default is 60 seconds. Valid time periods range from 5-86400 seconds (24 hours). |
filter-extension extension-list |
(Optional) String containing a comma-separated list of file extensions to which metadata caching is to be applied. Do not include the dot at the beginning of the file extension. You can specify a maximum of 20 file extensions. |
https enable |
(Optional) Enables metadata caching for HTTPS traffic. |
sharepoint-opt prefetch enable |
(Optional) Enables data to be prefetched from the SharePoint server and serve it from the cache to the client. |
suppress-server-encoding enable |
(Optional) Enables suppression of Accept-Encoding compress, gzip, and deflate request-headers between the client and the server for HTTP and HTTPS. |
Defaults
The HTTP accelerator is enabled by default and will start automatically if the Enterprise license is installed. The default exception action is coredump.
The metadata caching feature is disabled by default for all response types. The default max-age is 86400 seconds (24 hours), the default min-age is 60 seconds, and the default filter extension list is empty (meaning that metadata caching is applied to all extension types).
The SharePoint optimization feature is disabled by default.
When suppress-server-encoding is enabled, it suppresses the server compression for both HTTP and HTTPS requests. The suppress server encoding feature is disabled by default.
The DRE hints feature applies to both HTTP and HTTPS requests. It is disabled by default.
The subnet feature is enabled after the subnet configuration is added.
Command Modes
global configuration
Device Modes
application-accelerator
Usage Guidelines
Use the accelerator http enable command to enable the acceleration of HTTP traffic.
You can enable or disable each of three metadata caches (conditional-response, redirect-response, and unauthorized-response) separately. By default they are all enabled when you enable HTTP metadata caching. If you disable the HTTP accelerator, metadata caching is also disabled.
When you enable the suppress-server-encoding feature, the WAE removes the Accept-Encoding header from HTTP requests, preventing the web server from compressing HTTP data that it sends to the client. This allows the WAE to apply its own compression to the HTTP data, typically resulting in much better compression than the web server.
Use the SharePoint optimization feature when you need to access Microsoft Office documents stored on a SharePoint server 2010, using a web browser. Enabling this feature will prefetch the data from the server and serve it from the cache, which reduces latency and improves the user experience.
The DRE hint feature improves DRE performance. This feature is not automatically enabled when metadata caching or the suppress server encoding feature is enabled.
The options request-ignore-no-cache and response-ignore-no-cache are disabled by default. Because the HTTP accelerator is conservative in caching client request metadata and server response metadata, deployments may want to test with these settings enabled to improve the HTTP metadata cache hit ratio to achieve less latency.
If an existing subnet configuration gets modified or removed, the new configuration applies to new connections only, and does not impact the existing HTTP sessions. The change takes effect only after the change is updated in the kernel. Only one ACL is associated with each feature and a new subnet configuration replaces the old one. Use the no command to remove the subnet configuration. If the HTTP AO feature is globally disabled, the feature is not applied to any session. If the HTTP AO feature is globally enabled, and if the acl lookup result for this session is permit, the feature applies to the session; otherwise, it does not apply. HTTP AO bypass-list takes precedence over this feature.
Examples
The following example shows how to enable the HTTP application accelerator:
WAE(config)# accelerator http enable
The following example shows how to enable and configure the metadata cache to operate only on specific file types:
WAE(config)# accelerator http metadatacache enable
WAE(config)# accelerator http metadatacache filter-extension html,css,jpg,gif
Related Commands
(config) accelerator ica
To enable the ICA application accelerator, use the accelerator ica global configuration command. To disable the ICA application accelerator, use the no form of this command.
accelerator ica {enable | exception {coredump | debug | no-coredump} | wansecure-mode {always | none}}
accelerator ica {enable | exception {coredump | debug | no-coredump} | wansecure-mode {always | none}}
Syntax Description
Defaults
The ICA accelerator is enabled by default. The default exception action is coredump. The default WAN Secure mode state is none.
Command Modes
global configuration
Device Modes
application-accelerator
Usage Guidelines
Use the accelerator ica enable command to enable the acceleration of ICA (Independent Computing Architecture) traffic with the transparent ICA accelerator. The ICA application accelerator provides WAN optimization on a WAAS device for ICAtraffic which is used to access a virtual desktop infrastructure (VDI). This is done through a process that is both automatic and transparent to the client and server.
Use the accelerator ica wansecure-mode always command to enable WAN Secure mode for ICA. The WAN Secure mode configuration in both of the peer WAEs must match in order for the ICA accelerator to optimize connections.
WAN Secure mode requires that the SSL application accelerator is enabled. Use the accelerator ssl enable global configuration command to enable the SSL accelerator.
Examples
The following example shows how to enable the ICA application accelerator:
WAE(config)# accelerator ica enable
Related Commands
(config) accelerator mapi
To enable the MAPI application accelerator, use the accelerator mapi global configuration command. To disable the MAPI application accelerator, or one of its options, use the no form of this command.
accelerator mapi {enable | encryption | read-opt | write-opt | reserved-pool-size maximum-percent max_percent | wansecure-mode {always | auto | none} |
exception {coredump | debug | no-coredump}}
no accelerator mapi {enable | encryption | read-opt | write-opt | reserved-pool-size maximum-percent max_percent | wansecure-mode {always | auto | none} |
exception {coredump | debug | no-coredump}}
Syntax Description
Defaults
The MAPI accelerator is enabled by default and will start automatically if the Enterprise license is installed. Encrypted MAPI traffic acceleration is not enabled by default. The read optimization (read-opt) and write optimization (write-opt) features are enabled by default when the MAPI accelerator is enabled. The default maximum reserved connection pool percent is 15. The default WAN secure mode is auto. The default exception action is coredump.
Command Modes
global configuration
Device Modes
application-accelerator
Usage Guidelines
Use the accelerator mapi enable command to enable MAPI acceleration. This feature supports Microsoft Outlook 2000-2007 clients. Secure connections that use message authentication (signing) or encryption are not accelerated and MAPI over HTTP is not accelerated.
You must enable the EPM accelerator before the MAPI accelerator can operate.
Use the reserved-pool-size keyword to restrict the maximum number of connections reserved for MAPI optimization during TFO overload. It is specified as a percent of the TFO connection limit of the platform. Valid percent ranges from 5%-50%. The default is 15% which would reserve approximately 0.5 connection for each client-server Association Group (AG) optimized by MAPI accelerator.
The client maintains at least one AG per server it connects to with an average of about 3 connections per AG. For deployments that observe a greater average number of connections per AG, or where TFO overload is a frequent occurrence, a higher value for the reserved pool size maximum percent is recommended.
Reserved connections would remain unused when the device is not under TFO overload. Reserved connections are released when the AG terminates.
Examples
The following example shows how to enable the MAPI application accelerator:
WAE(config)# accelerator mapi enable

(config) accelerator nfs
To enable the NFS application accelerator, use the accelerator nfs global configuration command. To disable the NFS application accelerator, use the no form of this command.
accelerator nfs {enable | exception {coredump | debug | no-coredump}}
no accelerator nfs {enable | exception {coredump | debug | no-coredump}}
Syntax Description
Defaults
The NFS accelerator is enabled by default and will start automatically if the Enterprise license is installed. The default exception action is coredump.
Command Modes

Syntax Description
Defaults
The SMB accelerator is disabled by default.
Command Modes
global configuration
Device Modes
application-accelerator
Usage Guidelines
The enterprise license is required to start the SMB accelerator. Enabling the SMB accelerator disables the CIFS accelerator if it is enabled.
The EXEC mode command show running-config displays non-default settings only. Therefore, the command no accelerator smb enable does not show up in the running configuration if the SMB accelerator is disabled, while the accelerator smb enable command does display if the SMB accelerator is enabled.
Examples
The following example shows how to enable the SMB application accelerator:
WAE(config)# accelerator smb enable

Syntax Description
Defaults
The local authentication method is enabled by default.
Command Modes
global configuration
Device Modes
application-accelerator
central-manager
Usage Guidelines
The authentication command configures both the authentication and authorization methods that govern login and configuration access to the WAAS device.
Note We strongly recommend that you use the WAAS Central Manager GUI instead of the WAAS CLI to configure administrative login authentication and authorization for your WAAS devices, if possible. For information about how to use the WAAS Central Manager GUI to centrally configure administrative login authentication and authorization on a single WAE or group of WAEs, which are registered with a WAAS Central Manager, see the Cisco Wide Area Application Services Configuration Guide.
The authentication login command determines whether the user has any level of permission to access the WAAS device. The authentication configuration command authorizes the user with privileged access (configuration access) to the WAAS device.
The authentication login local and the authentication configuration local commands use a local database for authentication and authorization.
The authentication login tacacs and authentication configuration tacacs commands use a remote TACACS+ server to determine the level of user access. The WAAS software supports only TACACS+ and not TACACS or Extended TACACS.
To configure TACACS+, use the authentication and tacacs commands. To enable TACACS+, use the tacacs enable command. For more information on TACACS+ authentication, see the (config) tacacs command.
The authentication login radius and authentication configuration radius commands use a remote RADIUS server to determine the level of user access.
By default, the local method is enabled, with TACACS+ and RADIUS both disabled for login and configuration. Whenever TACACS+ and RADIUS are disabled the local method is automatically enabled. TACACS+, RADIUS, and local methods can be enabled at the same time.
The primary option specifies the first method to attempt for both login and configuration; the secondary option specifies the method to use if the primary method fails. The tertiary option specifies the method to use if both primary and secondary methods fail. The quaternary option specifies the method to use if the primary, secondary, and tertiary methods fail. If all methods of an authentication login or authentication configuration command are configured as primary, or all as secondary or tertiary, local is attempted first, then TACACS+, and then RADIUS.
Enforcing Authentication with the Primary Method
The authentication fail-over server-unreachable global configuration command allows you to specify that a failover to the secondary authentication method should occur only if the primary authentication server is unreachable. This feature ensures that users gain access to the WAAS device using the local database only when remote authentication servers (TACACS+ or RADIUS) are unreachable. For example, when a TACACS+ server is enabled for authentication with a user authentication failover configured and the user tries to log in to the WAAS device using an account defined in the local database, login fails. Login succeeds only when the TACACS+ server is unreachable.
You can configure multiple TACACS+ or RADIUS servers; authentication is attempted on the primary server first. If the primary server is unreachable, then authentication is attempted on the other servers in the TACACS+ or RADIUS farm, in order. If authentication fails for any reason other than a server is unreachable, authentication is not attempted on the other servers in the farm. This process applies regardless of the setting of the authentication fail-over server-unreachable command.
Login Authentication and Authorization Through the Local Database
Local authentication and authorization uses locally configured login and passwords to authenticate administrative login attempts. The login and passwords are local to each WAAS device and are not mapped to individual usernames.
By default, local login authentication is enabled first. You can disable local login authentication only after enabling one or more of the other administrative login authentication methods. However, when local login authentication is disabled, if you disable all other administrative login authentication methods, local login authentication is reenabled automatically.
Specifying RADIUS Authentication and Authorization Settings
To configure RADIUS authentication on a WAAS device, you must first configure a set of RADIUS authentication server settings on the WAAS device by using the radius-server global configuration command. (See the (config) radius-server command.)
Use the authentication login radius global configuration command to enable RADIUS authentication for normal login mode.
Use the authentication configuration radius global configuration command to enable RADIUS authorization.
To disable RADIUS authentication and authorization on a WAAS device, use the no form of the authentication global configuration command (for example, use the no authentication login radius enable command to disable RADIUS authentication).
Specifying TACACS+ Authentication and Authorization Settings
To configure TACACS+ authentication on WAAS devices, you must configure a set of TACACS+ authentication settings on the WAAS device by using the tacacs global configuration command. (See the (config) tacacs command.)
Server Redundancy
Authentication servers can be specified with the tacacs host or radius-server host global configuration commands. In the case of TACACS+ servers, the tacacs host hostname command can be used to configure additional servers. These additional servers provide authentication redundancy and improved throughput, especially when WAAS device load-balancing schemes distribute the requests evenly between the servers. If the WAAS device cannot connect to any of the authentication servers, no authentication takes place and users who have not been previously authenticated are denied access. Secondary authentication servers are queried in order only if the primary server is unreachable. If authentication fails for any other reason, alternate servers are not queried.
Specifying the Windows Domain Login Authentication
You can enable the Windows domain as an administrative login authentication and authorization method for a device or device group. Before you enable Windows authentication, you must first configure the Windows domain controller by using the windows-domain wins-server global configuration command. (See the (config) windows-domain command.)
Note WAAS supports authentication by a Windows domain controller running only on Windows Server 2000 or Windows Server 2003.
Examples
The following example shows how to query the secondary authentication database if the primary authentication server is unreachable. This feature is referred to as the failover server-unreachable feature.
WAE(config)# authentication fail-over server-unreachable
If you enable the failover server-unreachable feature on the WAAS device, only two login authentication schemes (a primary and secondary scheme) can be configured on the WAAS device. The WAAS device fails over from the primary authentication scheme to the secondary authentication scheme only if the specified authentication server is unreachable.
To enable authentication privileges using the local, TACACS+, RADIUS, or Windows databases, and to specify the order of the administrative login authentication, use the authentication login global configuration command. In the following example, RADIUS is specified as the primary method, TACACS+ as the secondary method, Windows as the third method, and the local database as the fourth method. In this example, four login authentication methods are specified because the failover server-unreachable feature is not enabled on the WAAS device.
WAE(config)# authentication login radius enable primary
WAE(config)# authentication login tacacs enable secondary
WAE(config)# authentication login windows-domain enable tertiary
WAE(config)# authentication login local enable quaternary
Note If you enable the failover server unreachable feature on the WAAS device, make sure that you specify either TACACS+ or RADIUS as the primary scheme for authentication, and specify local as the secondary scheme for authentication.
To enable authorization privileges using the local, TACACS+, RADIUS, or Windows databases, and to specify the order of the administrative login authorization (configuration), use the authentication configuration global configuration command.
Note Authorization privileges apply to console and Telnet connection attempts, secure FTP (SFTP) sessions, and Secure Shell (SSH Version 2) sessions.
We strongly recommend that you set the administrative login authentication and authorization methods in the same order. For example, configure the WAAS device to use RADIUS as the primary login method, TACACS+ as the secondary login method, Windows as the tertiary method, and the local method as the quaternary method for both administrative login authentication and authorization.
The following example shows that RADIUS is specified as the primary method, TACACS+ as the secondary method, Windows as the third method, and the local database as the fourth method. In this example, four login authorization (configuration) methods are specified because the failover server-unreachable feature is not enabled on the WAAS device.
WAE(config)# authentication configuration radius enable primary
WAE(config)# authentication configuration tacacs enable secondary
WAE(config)# authentication configuration windows-domain enable tertiary
WAE(config)# authentication configuration local enable quaternary
Note If you enable the failover server unreachable feature on the WAAS device, make sure that you specify either TACACS+ or RADIUS as the primary scheme for authorization (configuration), and specify local as the secondary scheme for authorization (configuration).
The following example shows the resulting output of the show authentication command:
WAE# show authentication user
Login Authentication: Console/Telnet/Ftp/SSH Session
----------------------------- ------------------------------

Note Authorization privileges apply to console and Telnet connection attempts, secure FTP (SFTP) sessions, and Secure Shell (SSH Version 2) sessions.
We strongly recommend that you set the administrative login authentication and authorization methods in the same order. For example, configure the WAAS device to use RADIUS as the primary login method, TACACS+ as the secondary login method, Windows as the tertiary method, and the local method as the quaternary method for both administrative login authentication and authorization.
The following example shows that RADIUS is specified as the primary method, TACACS+ as the secondary method, Windows as the third method, and the local database as the fourth method. In this example, four login authorization (configuration) methods are specified because the failover server-unreachable feature is not enabled on the WAAS device.
WAE(config)# authentication configuration radius enable primary
WAE(config)# authentication configuration tacacs enable secondary
WAE(config)# authentication configuration windows-domain enable tertiary
WAE(config)# authentication configuration local enable quaternary
Note If you enable the failover server unreachable feature on the WAAS device, make sure that you specify either TACACS+ or RADIUS as the primary scheme for authorization (configuration), and specify local as the secondary scheme for authorization (configuration).
The following example shows the resulting output of the show authentication command:
WAE# show authentication user
Login Authentication: Console/Telnet/Ftp/SSH Session
----------------------------- ------------------------------
local enabled (primary)
Windows domain enabled
Radius disabled
Tacacs+ disabled
Configuration Authentication: Console/Telnet/Ftp/SSH Session
----------------------------- ------------------------------

To activate the strong password policy on a WAAS device, use the authentication strict-password-policy global configuration command. To deactivate the strong password policy and use the standard password policy on a WAAS device, use the no form of this command.
authentication strict-password-policy [max-retry-attempts number]
no authentication strict-password-policy [max-retry-attempts number]
Syntax Description
max-retry-attempts number |
(Optional) Specifies the maximum number of failed login attempts allowed before the user is locked out. The range is 1-25; the default is 3. |
Defaults
The strong password policy is enabled on the WAAS device.
Command Modes
global configuration
Device Modes
application-accelerator
central-manager
Usage Guidelines
When you enable the strong password policy, your user passwords must meet the following requirements:
•The password must be 8 to 31 characters long.
•The password can include both uppercase and lowercase letters (A-Z and a-z), numbers (0-9), and special characters including ~`!@#$%^&*()_+-=[]\{};:,</>.
•The password cannot contain all the same characters (for example, 99999).
•The password cannot contain consecutive characters (for example, 12345).
•The password cannot be the same as the username.
•Each new password must be different from the previous 12 passwords. User passwords expire within 90 days.
•The password cannot contain the characters ' " |
(apostrophe, double quote, or pipe) or any control characters.
•The password cannot contain dictionary words.
When you disable the strong password policy, user passwords must meet the following requirements:
•The password must have 1 to 31 characters.
•The password can include both uppercase and lowercase letters (A-Z and a-z), and numbers (0-9).
•The password cannot contain the characters ' " |
(apostrophe, double quote, or pipe) or any control characters.
Note When you enable the strong password policy, existing standard-policy passwords will still work. However, these passwords are subject to expiration under the strong password policy.
Examples
The following example shows how to enable the strong password policy:
WAE(config)# authentication strict-password-policy
The following example shows how to enable the strong password policy and set the maximum retry attempts to 5:
WAE(config)# authentication strict-password-policy max-retry-attempts 5

(config) auto-discovery
To configure a WAE to automatically discover origin servers (such as those servers behind firewalls) that cannot receive TCP packets with setup options and add these server IP addresses to a blacklist for a specified number of minutes, use the auto-discovery global configuration command. To disable auto-discovery, use the no form of this command.
auto-discovery blacklist {enable | hold-time minutes}
no auto-discovery blacklist {enable | hold-time minutes}
Syntax Description
Defaults
The default auto-discovery blacklist hold time is 60 minutes.
Command Modes
global configuration
Device Modes
application-accelerator
Usage Guidelines
Use the auto-discovery blacklist hold-time command to adjust the blacklist hold time for the TFO auto-discovery feature. With auto-discovery, the WAE keeps track of origin servers (such as those servers behind firewalls) that cannot receive TCP packets with options and learns not to send out TCP packets with options to these blacklisted servers. When a server IP address is added to the blacklist, it remains on the blacklist for the configured number of minutes. After the hold time expires, subsequent connection attempts will again include TCP options so that the WAE can redetermine if the server can receive them. Resending TCP options periodically is useful because network packet loss could cause a server to be blacklisted erroneously.
Examples
The following example shows how to enable TFO auto-discovery blacklist using the auto-discovery command:
WAE(config)# auto-discovery blacklist enable
Related Commands
show statistics auto-discovery
(config) auto-register
To enable the discovery of a WAE and its automatic registration with the WAAS Central Manager through the Dynamic Host Configuration Protocol (DHCP), use the auto-register global configuration command. To disable the autoregistration feature on a WAE, use the no form of this command.
auto-register enable [FastEthernet slot/port | GigabitEthernet slot/port | TenGigabitEthernet slot/port]
no auto-register enable [FastEthernet slot/port | GigabitEthernet slot/port | TenGigabitEthernet slot/port] [preserve-ip]
Syntax Description
Defaults
Automatic registration using DHCP is enabled on a WAE by default.
Command Modes
global configuration
Device Modes
application-accelerator
appnav-controller
Usage Guidelines
Autoregistration automatically configures network settings and registers WAEs with the WAAS Central Manager. On bootup, devices that run the WAAS software (with the exception of the WAAS Central Manager) automatically discover the WAAS Central Manager and register with it. You do not have to do any manual configuration on the device. Once the WAE is registered, you can approve the device and configure it remotely using the WAAS Central Manager GUI.
You can use the auto-register enable command to allow a WAE to discover the hostname of the WAAS Central Manager through DHCP and to automatically register the device with the WAAS Central Manager. Discovery and registration occur at bootup.
Note You must disable autoregistration when both device interfaces are configured as port-channel interfaces.
Note The DHCP that is used for autoregistration is not the same as the interface-level DHCP that is configurable through the ip address dhcp interface configuration command.
To assign a static IP address using the interface command, you must first disable the automatic registration of devices through DHCP by using the no auto-register enable command. If you want to keep the dynamic IP address that had been assigned to the interface, use the preserve-ip option to convert it to a static IP address.
After the WAE configures its network settings from DHCP, it needs to know the Central Manager hostname so it can register with the Central Manager.
The WAE queries the DNS server to obtain the Central Manager hostname. For autoregistration to work, you must configure the DNS server with the Central Manager hostname by configuring a DNS SRV (Service Location) record. For more information about autoregistration and how to configure the DNS SRV record, see the section on autoregistration in the "Planning Your WAAS Network" chapter of the Cisco Wide Area Application Services Configuration Guide.
Examples
The following example shows how to enable autoregistration on GigabitEthernet port 1/0:
WAE(config)# auto-register enable GigabitEthernet 1/0
The following example shows how to disable autoregistration on all configured interfaces on the WAE without losing any IP addresses assigned by autoregistration DHCP:
WAE(config)# no auto-register enable preserve-ip

(config) banner
To configure the EXEC, login, and message-of-the-day (MOTD) banners, use the banner global configuration command. To disable the banner feature, use the no form of this command.
banner {enable | {{exec | login | motd} [message text]}}
no banner {enable | {{exec | login | motd} [message text]}}
Syntax Description
Defaults
Banner support is disabled by default.
Command Modes
global configuration
Usage Guidelines
The message keyword is optional. If you enter a carriage return without specifying the message keyword, you will be prompted to enter your message text. For message text on one or more lines, press the Return key or enter delimiting characters (\n) to specify a message to appear on a new line. You can enter up to a maximum of 980 characters, including new-line characters (\n). Enter a period (.) at the beginning of a new line to save the message and return to the prompt for the global configuration mode.
Note The EXEC banner content is obtained from the command-line input that you enter when prompted for the input.
After you configure the banners, enter the banner enable global configuration command to enable banner support on the appliance. Enter the show banner EXEC command to display information about the configured banners.
Examples
The following example shows how to use the banner motd message global configuration command to configure the MOTD banner. In this example, the MOTD message consists of a single line of text.
WAE(config)#
banner motd message This is a WAAS 4.0.7 device
The following example shows how to use the banner motd message global command to configure a MOTD message that is longer than a single line. In this case, the WAE translates the \n portion of the message to a new line when the MOTD message is displayed to the user.
WAE(config)#
banner motd message "This is the motd message.
\nThis is a WAAS 4.0.7 device\n"
The following example shows how to use the banner login message global configuration command to configure a login message that is longer than a single line. In this case, WAE A translates the \n portion of the message to a new line in the login message that is displayed to the user.
WAE(config)#
banner login message "This is login banner.
\nUse your password to login\n"
The following example shows how to enable banner support:
WAE(config)#
banner enable
The following example shows how to use the banner exec global configuration command to configure an interactive banner. The banner exec command is similar to the banner motd message commands except that for the banner exec command, the banner content is obtained from the command-line input that the user enters after being prompted for the input.
WAE(config)# banner exec
Please type your MOTD messages below and end it with '.' at beginning of line:
(plain text only, no longer than 980 bytes including newline)
This is the EXEC banner.\nUse your WAAS username and password to log in to this WAE.\n
.
Message has 99 characters.
WAE(config)#
Assume that a WAE has been configured with the MOTD, login, and EXEC banners as shown in the previous examples. When a user uses an SSH session to log in to the WAE, the user will see a login session that includes a MOTD banner and a login banner that asks the user to enter a login password as follows:
This is the motd banner.
This is a WAAS 4.0.7 device
This is login banner.
Use your password to login.
Cisco Wide Area Application Services Engine
admin@wae's password:
After the user enters a valid login password, the EXEC banner is displayed, and the user is asked to enter the WAAS username and password as follows:
Last login: Fri Oct 1 14:54:03 2004 from client
System Initialization Finished.
This is the EXEC banner.
Use your WAAS username and password to log in to this WAE.
After the user enters a valid WAAS username and password, the WAE CLI is displayed. The CLI prompt varies depending on the privilege level of the login account. In the following example, because the user entered a username and password that had administrative privileges (privilege level of 15), the EXEC mode CLI prompt is displayed:

Command Modes
global configuration
Device Modes
application-accelerator
appnav-controller
Usage Guidelines
This command can create a bridge group for bridging to a virtual blade, by using the protocol ieee option. After using this command, create a bridge virtual interface in the bridge group by using the interface bvi global configuration command. You must add one physical, port-channel, or standby interface to the bridge group, along with the BVI interface.
This command can also create a bridge group for bridging two inline interfaces for interception on an AppNav Controller Interface Module in an AppNav deployment, by using the protocol interception option. The two member interfaces of this kind of bridge group do not need to be similar. For example, one could be a physical interface and one could be a port-channel interface. A standby interface is not allowed in a bridge group for inline interception on an AppNav Controller Interface Module.

(config) class-map
To configure an AppNav or optimization class map, use the class-map global configuration command. To unconfigure settings, use the no form of this command.
class-map type {appnav | waas} [match-all | match-any] classmap-name [rename new-name]
no class-map type {appnav | waas} [match-all | match-any] classmap-name
Syntax Description
Defaults
For AppNav class maps, match-all is the default when multiple match criteria exist.
Command Modes
global configuration
Device Modes
application-accelerator
appnav-controller
Usage Guidelines
Use the class-map command to add or modify class maps and match conditions to identify specific types of traffic for use in policies. This command invokes the Class Map configuration mode, which is indicated by a different prompt (config-cmap). For more information on Class Map configuration mode commands, see the "Class Map Configuration Mode Commands" section. To return to global configuration mode, enter the exit command.
You can delete a class map by using the no form of this command. You cannot delete a class map if any policies are using it.
When creating a new class map, you must add at least one condition. If any of the conditions specified match an already existing condition in the class-map, no action is taken.
Note You cannot have more than 512 different class maps and 1024 total match conditions.
The WAAS software comes with many class maps and policy rules that help your WAAS system classify and optimize some of the most common traffic on your network. Before you create a new class map or policy rule, we recommend that you review the default class map and policy rules and modify them as appropriate. It is usually easier to modify an existing class map or policy rule than to create a new one. For a list of the default applications, class maps, and policy rules, see the Cisco Wide Area Application Services Configuration Guide.
Note We strongly recommend that you use the WAAS Central Manager GUI to centrally configure class maps for your WAAS devices. For more information, see the Cisco Wide Area Application Services Configuration Guide.
There is one exception this recommendation. Use the CLI to create an AppNav class map with type Application or Custom, and whose source or destination address has one of the following: an IP address ending in "0.0.0" or a non-Class A IP address ending in "0.0".
Examples
The following example shows how to configure a WAAS optimization class map:
wae(config)# class-map type waas myclass1
wae(config-cmap)# description My class number one
wae(config-cmap)# match protocol mapi tcp source ip 10.10.10.35
wae(config-cmap)# exit
The following example shows how to configure an AppNav class map:
wae(config)# class-map type appnav myclass1
wae(config-cmap)# match peer 50:3d:e5:9c:8f:aa description SanJose_branch
wae(config-cmap)# exit

Usage Guidelines
To set and display the local and UTC current time of day without an NTP server, use the clock timezone command with the clock set command. The clock timezone parameter specifies the difference between UTC and local time, which is set with the clock set EXEC command. The UTC and local time are displayed with the show clock detail EXEC command.
Note Unexpected time changes can result in unexpected system behavior. We recommend reloading the system after changing the system clock.
Use the clock timezone offset command to specify a time zone, where timezone is the desired time zone entry listed in the table below and 0 0 is the offset (ahead or behind) UTC is in hours and minutes. (UTC was formerly known as Greenwich mean time [GMT]).
WAE(config)# clock timezone timezone 0 0
Note The time zone entry is case sensitive and must be specified in the exact notation listed in Table 3-1. When you use a time zone entry from the time zone table, the system is automatically adjusted for daylight saving time.
Examples
The following example shows how to specify the local time zone as Pacific Standard Time with an offset of 8 hours behind UTC:

central-manager
Usage Guidelines
Use the cms database maintenance global configuration command to schedule routine full maintenance cleaning (vacuuming) or a regular maintenance reindexing of the embedded database. The full maintenance routine runs only when the disk is more than 90 percent full and only runs once a week. Cleaning the tables returns reusable space to the database system.
The cms enable global configuration command automatically registers the node in the database management tables and enables the CMS process. The no cms enable global configuration command only stops the management services on the WAAS device. Use the cms deregister EXEC command to de-register (remove) a WAAS device from the WAAS network.
Tip If you are trying to register a device that had previously been registered with a WAAS Central Manager and the cms enable global configuration command fails, use the cms deregister force command. If you get an error saying that the management service is not enabled when you use the cms deregister force command, delete the device from the WAAS Central Manager.
Examples
The following example shows how to schedule a regular (reindexing) maintenance routine to start every Friday at 11:00 p.m on the WAAS device:
WAE(config)# cms database maintenance regular schedule Fri at 23:00
The following example shows how to enable the CMS process on a WAAS device:

appnav-controller
Usage Guidelines
If the WAAS device is operating with an Accelerator only image, you will not be able to convert it to central-manager mode until after you update it with a Full image and reboot. You can use the show version EXEC command to check the type of software image the WAE is running.
Examples
The following example shows how to specify central manager as the device mode of a WAAS device:
WAE(config)# device mode central-manager
The following example shows how to specify application accelerator as the device mode of a WAAS device:
WAE(config)# device mode application-accelerator
To change the device mode from central-manager to application-accelerator or appnav-controller, you must first use the cms deregister command in EXEC mode to disable the Centralized Management System on the Central Manager. Then use the device mode command in global configuration mode, as shown in the following example:
WAE# cms deregister
WAE(config)# device mode application-accelerator
WAE# copy running-config startup-config

When extended object cache is enabled, the object cache space is increased only after saving the configuration and performing a reload.
Note If you have a virtual blade enabled using vbspace of greater than 30 GB, you must stop the virtual blade and remove the configuration before enabling extended object cache. If the virtual blade usage is less than 30 GB (including saved memory state) vbspace content will be preserved, otherwise vbspace content will be erased. In either case, after enabling extended object cache, the vbspace filesystem will be reduced to 30 GB if virtual blade is enabled.
The status of extended object cache can be displayed using the show disk details EXEC mode command. The output of this command states whether extended object cache is enabled or disabled.
This feature is supported only on WAVE-694, WAE-674-4G, and WAE-674-8G models.
When a device is changed to AppNav mode, a warning message tells the user that changing the Device mode to AppNav Controller, will forcefully disable disk object-cache extend.The new configuration will take effect after a reload. If the user confirms, the system proceeds with reloading the system configuration and the extended object cache is disabled.
Examples
The following example shows how to enable extended object cache:
WAE(config)# disk object-cache extend
Cumulative disk space for all VBs will be reduced to 30GB.

Syntax Description
Defaults
No default behaviors or values.
Command Modes
global configuration
Device Modes
application-accelerator
central-manager
appnav-controller
Usage Guidelines
Use the interception command to apply an access list (ACL) to traffic interception. Packets permitted by the ACL are intercepted for WAAS optimization (on an application accelerator device) or for distribution (on an ANC). Packets denied by the ACL are passed through by WAAS. You can define ACLs by using the ip access-list standard or ip access-list extended configuration commands.
Note On an ANC the tcp ... established
extended ACL rule type is not supported.
You can configure only one interception ACL, except if the device is an ANC that is also acting as a WN. In this situation, you can configure one interception appnav-controller access-list for the ANC and one interception access-list for the WN. The ANC ACL could permit a flow that is subsequently denied by the WN ACL.
If you specify an interception ACL that is not defined, it is considered to be a "permit any" ACL and all traffic is intercepted.
An interception ACL works both with WCCP and inline interception modes.
When used with interface ACLs and WCCP ACLs, the interface ACL is applied first, the WCCP ACL is applied second, and then the interception ACL is applied last.
Examples
The following example shows how to define and apply an ACL that intercepts all traffic except WWW traffic from a particular client:
dc-wae(config)# ip access-list extended iacl
dc-wae(config-ext-nacl)# deny tcp host 10.74.2.132 any eq www
dc-wae(config-ext-nacl)# permit ip any any
dc-wae(config-ext-nacl)# exit
dc-wae(config)# interception access-list iacl
The following example uses the same ACL for an ANC:
anc(config)# interception appnav-controller access-list iacl

Syntax Description
Defaults
The first attached interface in a standby group is defined as the active interface. There are no other default behaviors or values.
Command Modes
global configuration
Device Modes
application-accelerator
appnav-controller
central-manager
Usage Guidelines
Although the CLI contains the no interface option, you cannot apply the no command to an interface. The software displays the following error message: Removing of physical interface is not permitted.
To configure an interface bandwidth on a WAAS device, use the bandwidth interface configuration command. The bandwidth is specified in megabits per second (Mbps). Using this option automatically enables autosense on the interface.
Note Changing the interface bandwidth, duplex mode, or MTU can cause network disruption for up to 30 seconds. The best practice is to make such changes when traffic interception is disabled or at an off-peak time when traffic disruption is acceptable.
Using the cdp enable command in global configuration mode enables CDP globally on all the interfaces. If you want to control CDP behavior per interface, use the cdp enable command in interface configuration mode. The interface level control overrides the global control.
To display the interface identifiers (for example, interface GigabitEthernet 1/0), use the show running-config or show startup-config commands. The autosense, bandwidth, full-duplex, half-duplex, ip, and shutdown commands are listed separately in this command reference.
Note When you use the ip address command to change the IP address of an interface that has been shut down, it automatically brings up that interface by default.
Configuring Multiple Secondary IP Addresses on a Single Physical Interface
Use the interface secondary global configuration command to configure more than one IP address on the same interface. By configuring multiple IP addresses on a single interface, the WAAS device can be present in more than one subnet. This configuration allows you to optimize the response time because the content goes directly from the WAAS device to the requesting client without being redirected through a router. The WAAS device becomes visible to the client because they are configured on the same subnet.
You can assign up to four secondary addresses to an interface. These addresses become active only after you configure the primary address. No two interfaces can have the same IP address in the same subnetwork. To set these secondary IP addresses, use the ip address command.
If a WAAS device has one physical interface that has multiple secondary IP addresses assigned to it, the egress traffic uses the source IP address that is chosen by IP routing. If the secondary IP addresses of a WAAS device in the same subnet as the primary IP address, then the egress traffic uses the primary IP address only. If the secondary IP addresses are in a different subnet than the primary IP address, then the destination IP address determines which IP address on the WAAS device is used for the egress traffic.
Configuring Interfaces for DHCP
When you configure a WAAS device initially, you can configure a static IP address or use interface-level DHCP to dynamically assign IP addresses to the interfaces on the WAAS device.
If you do not enable interface-level DHCP on the WAAS device, you must manually specify a static IP address and network mask for the WAAS device. If the WAAS device moves to another location in another part of the network, you must manually enter a new static IP address and network mask for this WAAS device.
You can enable an interface for DHCP using the ip address dhcp client-id id hostname name interface configuration command. The client identifier is an ASCII value. The WAAS device sends its configured client identifier and hostname to the DHCP server when requesting network information. You can configure DHCP servers to identify the client identifier and the hostname that the WAAS device is sending and then send the specific network settings that are assigned to the WAAS device.
Note You must disable autoregistration before you can manually configure an interface for DHCP. Autoregistration is enabled by default on the first interface of the device.
Defining Interface Descriptions
You can specify a one-line description for a specific interface on a WAAS device. Use the description text interface configuration command to enter the description for the specific interface. The maximum length of the description text is 240 characters. This feature is supported for the Gigabit Ethernet, 10 Gigabit Ethernet, port-channel, standby, and bridge virtual interfaces.
After you define the description for an interface, use the show EXEC commands to display the defined interface descriptions. Enter the show interface interface type slot/port EXEC command to display the defined description for a specific interface on the WAE.
Configuring a Standby Group
You can associate an interface with a standby group by using the standby group-index interface configuration command. To make an interface the active interface in a standby group, use the standby group-index primary interface configuration command. If you have already associated an interface with a standby group but have not made it the primary interface, you cannot specify the command again to add the primary designation. First, remove the interface from the standby group, then reassign it, specifying the primary option at the same time.
A physical interface can be a member of a standby group or a port channel, but not both.
If a device has only two interfaces, you cannot assign an IP address to both a standby group and a port channel. On such a device, only one virtual interface can be configured with an IP address.
Examples
The following example shows how to configure an attribute of an interface with a single CLI command:
WAE(config)# interface GigabitEthernet 1/0 full-duplex

Usage Guidelines
An InlineGroup interface is a logical grouping of a pair of Ethernet ports that are physically contained on the optional Cisco WAE Inline Network Adapter or Cisco Interface Module. This command does not apply to the Cisco AppNav Controller Interface Module; use the (config) bridge command to configure an inline bridge on that platform.
You can have multiple InlineGroup interfaces, which allows for multiple bypass-enabled paths for traffic to pass through the WAE appliance, making multiple-router deployments possible. The InlineGroup interfaces provide failover capability and can be assigned to any set of VLANs. (For examples of InlineGroup interface configurations, see the (config-if) inline command.)
You can configure the InlineGroup interface for link speed (bandwidth or autosense) and mode of operation (half-duplex or full-duplex).
The failover timeout set by this command applies only to interfaces on the Cisco WAE Inline Network Adapter. To set the failover timeout for all interfaces together on the Cisco Interface Module, use the (config) inline command.
Note If the VLAN ID that you set with the encapsulation dot1q option does not match the VLAN ID expected by the router subinterface, you may not be able to connect to the inline interface IP address.
The inline adapter supports only a single VLAN ID for each inline group interface. If you have configured a secondary address from a different subnet on an inline interface, you must have the same secondary address assigned on the router subinterface for the VLAN.
Note We strongly recommend that you do not use half duplex on the WAE, routers, switches, or other devices. Use of half-duplex impedes system ability to improve performance and should not be used. Double-check each Cisco WAE interface as well as the port configuration on the adjacent device (router, switch, firewall, WAE) to verify that full duplex is configured.

Usage Guidelines
Port channels (EtherChannels) for the WAAS software support the grouping of multiple same-speed network interfaces into one virtual interface. This configuration allows you to set or remove a virtual interface that consists of up to four physical interfaces (eight on an AppNav Controller Interface Module). Port channels also provide interoperability with Cisco routers, switches, and other networking devices or hosts that support port channels, load balancing, and automatic failure detection and recovery based on the current link status of each interface. You must configure port channels on the switch or router if you configure it on the WAE.
You cannot add an interface that already has a configured IP address, or is configured as primary or secondary, to a port channel.
You cannot remove a port-channel interface that is configured as the primary interface on a WAE.
Note You cannot use the inline Ethernet interfaces that are located on the Cisco WAE Inline Network Adapter to form a port-channel interface. However, you can use the interfaces on a Cisco Interface Module to form a port-channel interface.
Note No two interfaces can have IP addresses in the same subnet.
Examples
The following example shows how to create a port-channel interface. The port channel is port channel 1 and is assigned an IP address of 10.10.10.10 and a netmask of 255.0.0.0:
WAE#
configure
WAE(config)#
interface PortChannel 1
WAE(config-if)#
ip address 10.10.10.10 255.0.0.0
WAE(config-if)#

Usage Guidelines
Although the CLI contains the no interface option, you cannot apply the no command to an interface. The software displays the following error message: Removing of physical interface is not permitted.
Note Changing the MTU can cause network disruption for up to 30 seconds. The best practice is to make such changes when traffic interception is disabled or at an off-peak time when traffic disruption is acceptable.
Using the cdp enable command in global configuration mode enables CDP globally on all the interfaces. If you want to control CDP behavior per interface, use the cdp enable command in interface configuration mode. The interface level control overrides the global control.
To display the interface identifiers (for example, interface TenGigabitEthernet 1/0), use the show running-config or show startup-config commands. The ip and shutdown commands are listed separately in this command reference.
Note When you use the ip address command to change the IP address of an interface that has been shut down, it automatically brings up that interface by default.
Configuring Multiple Secondary IP Addresses on a Single Physical Interface
Use the interface secondary global configuration command to configure more than one IP address on the same interface. By configuring multiple IP addresses on a single interface, the WAAS device can be present in more than one subnet. This configuration allows you to optimize the response time because the content goes directly from the WAAS device to the requesting client without being redirected through a router. The WAAS device becomes visible to the client because they are configured on the same subnet.
You can assign up to four secondary addresses to an interface. These addresses become active only after you configure the primary address. No two interfaces can have the same IP address in the same subnetwork. To set these secondary IP addresses, use the ip address command.
If a WAAS device has one physical interface that has multiple secondary IP addresses assigned to it, the egress traffic uses the source IP address that is chosen by IP routing. If the secondary IP addresses of a WAAS device in the same subnet as the primary IP address, then the egress traffic uses the primary IP address only. If the secondary IP addresses are in a different subnet than the primary IP address, then the destination IP address determines which IP address on the WAAS device is used for the egress traffic.
Configuring Interfaces for DHCP
When you configure a WAAS device initially, you can configure a static IP address or use interface-level DHCP to dynamically assign IP addresses to the interfaces on the WAAS device.
If you do not enable interface-level DHCP on the WAAS device, you must manually specify a static IP address and network mask for the WAAS device. If the WAAS device moves to another location in another part of the network, you must manually enter a new static IP address and network mask for this WAAS device.
You can enable an interface for DHCP using the ip address dhcp client-id id hostname name interface configuration command. The client identifier is an ASCII value. The WAAS device sends its configured client identifier and hostname to the DHCP server when requesting network information. You can configure DHCP servers to identify the client identifier and the hostname that the WAAS device is sending and then send the specific network settings that are assigned to the WAAS device.
Note You must disable autoregistration before you can manually configure an interface for DHCP. Autoregistration is enabled by default on the first interface of the device.
Defining Interface Descriptions
You can specify a one-line description for a specific interface on a WAAS device. Use the description text interface configuration command to enter the description for the specific interface. The maximum length of the description text is 240 characters. This feature is supported for the Gigabit Ethernet, 10 Gigabit Ethernet, port-channel, standby, and bridge virtual interfaces.
After you define the description for an interface, use the show EXEC commands to display the defined interface descriptions. Enter the show interface interface type slot/port EXEC command to display the defined description for a specific interface on the WAE.
Configuring a Standby Group
You can associate an interface with a standby group by using the standby group-index interface configuration command. To make an interface the active interface in a standby group, use the standby group-index primary interface configuration command. If you have already associated an interface with a standby group but have not made it the primary interface, you cannot specify the command again to add the primary designation. First, remove the interface from the standby group, and then reassign it, specifying the primary option at the same time.
A physical interface can be a member of a standby group or a port channel, but not both.
If a device has only two interfaces, you cannot assign an IP address to both a standby group and a port channel. On such a device, only one virtual interface can be configured with an IP address.
Examples
The following example shows how to configure an attribute of an interface with a single CLI command:
WAE(config)# interface TenGigabitEthernet 1/0 ip access-group 1 in
The following example shows that an interface can be configured in a sequence of CLI commands:

Usage Guidelines
To define a default gateway, use the ip default-gateway command. If you have designated a management interface, you can configure a different default gateway for the management interface by using the management keyword. To remove the IP default gateway, use the no form of this command. The WAAS device uses the default gateway to route IP packets when there is no specific route found to the destination.
To define a default domain name, use the ip domain-name command. To remove the IP default domain name, use the no form of this command. You can enter up to three domain names. If a request arrives without a domain name appended in its hostname, the proxy tries to resolve the hostname by appending name1, name2, and name3 in that order until one of these names succeeds.
To add an entry to the /etc/hosts file on the device, mapping a hostname to an IP address, use the ip host command. A given hostname can be mapped only to a single IP address, while an IP address can have multiple hostnames mapped to it, each one through a separate issuance of this command. To remove the entry from the /etc/hosts file, use the no form of this command. You can use the show hosts EXEC command to display the contents of the /etc/hosts file.
To specify the address of one or more name servers to use for name and address resolution, use the ip name-server ip-addresses command. To disable IP name servers, use the no form of this command. For proper resolution of the hostname to the IP address or the IP address to the hostname, the WAAS device uses DNS servers. Use the ip name-server command to point the WAAS device to a specific DNS server. You can configure up to eight servers.
Path MTU autodiscovery discovers the MTU and automatically sets the correct value. Use the ip path-mtu-discovery enable command to start this autodiscovery utility. By default, this feature is disabled because the WAE does not receive ICMP packets. When this feature is disabled, the sending device uses a packet size that is smaller than 576 bytes and the next hop MTU. Existing connections are not affected when this feature is turned on or off.
Use the ip route command to add a specific static route for a network or host. Any IP packet designated for the specified destination uses the configured route.
To configure static IP routing, use the ip route command. To remove the route, use the no form of this command. Do not use the ip route 0.0.0.0 0.0.0.0 command to configure the default gateway; use the ip default-gateway command instead.
Examples
The following example shows how to configure a default gateway for the WAAS device:
WAE(config)# ip default-gateway 192.168.7.18
The following example shows how to configure a default gateway for the management interface on the WAAS device, if it is different from the standard default gateway:
WAE(config)# ip default-gateway management 192.168.10.35
The following example shows how to configure a static IP route for the WAAS device:
WAE(config)# ip route 172.16.227.128 255.255.255.0 172.16.227.250
The following example shows how to configure a default domain name for the WAAS device:
WAE(config)# ip domain-name cisco.com
The following example shows how to add an entry to the /etc/hosts file on the WAAS device:
WAE(config)# ip host corp-B7 10.11.12.140
The following example shows how to configure a name server for the WAAS device:
WAE(config)# ip name-server 10.11.12.13
Related Commands
(config) ip access-list
To create and modify access lists on a WAAS device for controlling access to interfaces or applications, and to define subnets, use the ip access-list global configuration command. To disable an access list, use the no form of this command.
ip access-list {standard {acl-name | acl-num} | extended {acl-name | acl-num} | logging}
no ip access-list {standard {acl-name | acl-num} | extended {acl-name | acl-num} | logging}
Syntax Description
standard |
Enables standard ACL configuration mode. The CLI enters the standard ACL configuration mode in which all subsequent commands apply to the current standard access list. The (config-std-nacl) prompt appears: WAE(config-std-nacl)# See the "Standard ACL Configuration Mode Commands" section for details about working with entries in a standard access list and the commands available from the standard ACL configuration mode (config-std-nacl)#. |
extended |
Enables extended ACL configuration mode. The CLI enters the extended ACL configuration mode in which all subsequent commands apply to the current extended access list. The (config-ext-nacl) prompt appears: WAE(config-ext-nacl)# See the "Extended ACL Configuration Mode Commands" section for details about working with entries in an extended access list and the commands available from the extended ACL configuration mode (config-ext-nacl)#. |
acl-name |
Access list to which all commands entered from ACL configuration mode apply, using an alphanumeric string of up to 30 characters, beginning with a letter. |
acl-num |
Access list to which all commands entered from access list configuration mode apply, using a numeric identifier. For standard access lists, the valid range is 1 to 99; for extended access lists, the valid range is 100 to 199. |
logging |
Enables logging for all IP access lists. |
Defaults
An access list drops all packets unless you configure at least one permit entry.
Command Modes
global configuration
Device Modes
application-accelerator
central-manager
Usage Guidelines
Within ACL configuration mode, you can use the editing commands (list, delete, and move) to display the current condition entries, to delete a specific entry, or to change the order in which the entries will be evaluated. To return to global configuration mode, use the exit command at the ACL configuration mode prompt.
To create an entry, use a the deny or permit keyword and specify the type of packets that you want the WAAS device to drop or to accept for further processing. By default, an access list denies everything because the list is terminated by an implicit deny any entry. You must include at least one permit entry to create a valid access list.
Note IP ACLs that are defined on a router take precedence over the IP ACLs that are defined on the WAE. IP ACLs that are defined on a WAE take precedence over the WAAS application definition policies that are defined on the WAE.
After creating an access list, you can include the access list in an access group using the access-group command, which determines how the access list is applied. You can also apply the access list to a specific application using the appropriate command. A reference to an access list that does not exist is the equivalent of a permit any condition statement.
To work with access lists, enter either the ip access-list standard or ip access-list extended global configuration command. Identify the new or existing access list with a name up to 30 characters long beginning with a letter, or with a number. If you use a number to identify a standard access list, it must be between 1 and 99; for an extended access list, use a number from 100 to 199. You must use a standard access list for providing access to the SNMP server or to the TFTP gateway/server. However, you can use either a standard access list or an extended access list for providing access to the WCCP application.
After you identify the access list, the CLI enters the appropriate configuration mode and all subsequent commands apply to the specified access list. The prompt for each configuration mode is shown in the following examples.
WAE(config)# ip access-list standard test
WAE(config-std-nacl)# exit
WAE(config)# ip access-list extended test2
WAE(config-ext-nacl)#
To define a subnet, use either a standard or an extended ACL. In an HTTP AO subnet configuration, the access-list option must have at least one condition statement in it for it to exist. The list is terminated by an implicit deny any (standard access list) or deny ip any any (extended access list) condition statement. This statement applies to HTTP AO optimizations unless the ACL has an explicit permit all statement in it. If an acl name or acl number does not exist (if no condition statements exist in the access list), it is considered as an implicit permit any (standard access list) or permit ip any any(extended access list) condition statement. We recommend that you explicitly add permit any or deny any at the end of the ACL to make all the conditions clear for the subnet feature.
Use the ip access-list logging command to log denied packets.
Examples
The following example shows how to create an access list on the WAAS device. You create this access list to allow the WAAS device to accept all web traffic that is redirected to it but limit host administrative access using SSH:
WAE(config)# ip access-list extended example
WAE(config-ext-nacl)# permit tcp any any eq www
WAE(config-ext-nacl)# permit tcp host 10.1.1.5 any eq ssh
WAE(config-ext-nacl)# exit
The following example shows how to activate the access list for an interface:
WAE(config)# interface gigabitethernet 1/0
WAE(config-if)# ip access-group example in
WAE(config-if)# exit
The following example shows how this configuration appears when you enter the show running-configuration command:

(config) ip icmp rate-limit unreachable
To limit the rate at which Internet Control Message Protocol (ICMP) destination unreachable messages are generated, use the ip icmp rate-limit unreachable command in global configuration mode. To remove the rate limit, use the no form of this command.
ip icmp rate-limit unreachable df microseconds
no ip icmp rate-limit unreachable df microseconds
Syntax Description
Defaults
The default value is one ICMP destination unreachable message per 500 microseconds.
Command Modes
global configuration
Device Modes
application-accelerator
Usage Guidelines
This feature is enabled by default. The no ip icmp rate-limit unreachable df command turns off the previously configured rate limit.
The software maintains two timers: one for general destination unreachable messages and one for DF destination unreachable messages. Both share the same time limits and defaults. If the df option is not configured, the ip icmp rate-limit unreachable command sets the time values for DF destination unreachable messages. If the df option is configured, its time values remain independent from those of general destination unreachable messages.
Examples
The following example sets the rate of the ICMP destination unreachable message to one message every 10 microseconds:
WAE(config)# ip icmp rate-limit unreachable df 10
The following example turns off the previously configured rate limit:
WAE(config)# no ip icmp rate-limit unreachable df

Usage Guidelines
If the software receives a nonbroadcast packet destined for itself that uses an unknown protocol, it sends an ICMP protocol unreachable message back to the source. Similarly, if the software receives a packet that it is unable to deliver to the ultimate destination because it knows of no route to the destination address, it sends an ICMP host unreachable message to the source. This feature is enabled by default.

Usage Guidelines
All Windows 2000 domains are also Kerberos realms. Because the Windows 2000 domain name is also a DNS domain name, the Kerberos realm name for the Windows 2000 domain name is always in uppercase letters. This capitalization follows the recommendation for using DNS names as realm names in the Kerberos Version 5 protocol document (RFC-1510) and affects only interoperability with other Kerberos-based environments.
Note Your Windows domain server must have a Reverse DNS Zone configured for this command to execute successfully.
The KDC server and all hosts with Kerberos authentication configured must interact within a 5-minute window or authentication will fail. All hosts, especially the KDC, should be running NTP. For information about configuring NTP, see the (config) ntp command.
The KDC server and Admin server must have the same IP address. The default port number for both servers is port 88.
The kerberos command modifies the krb5.conf file.
Examples
The following example shows how to configure the WAAS device to authenticate with a specified KDC in a specified Kerberos realm. The configuration is then verified.
WAE(config)# kerberos ?
local-realm Set local realm name
realm Add domain to realm mapping
server Add realm to host mapping
WAE(config)# kerberos local-realm WAE.ABC.COM
WAE(config)# kerberos realm wae.abc.com WAE.ABC.COM

no kernel kdb
Syntax Description
This command has no arguments or keywords.
Defaults
The kernel debugger is disabled by default.
Command Modes
global configuration
Device Modes
application-accelerator
central-manager
Usage Guidelines
Once enabled, kdb is automatically activated if kernel problems occur, or you can manually activate it from the local console for the WAAS device. Once activated, all normal functioning of the WAAS device is suspended until kdb is manually deactivated. The kdb prompt looks like this:
[0]kdb>
To deactivate kdb, enter the go command at the kdb prompt. If kdb was automatically activated because of kernel problems, the system generates a core dump and restarts. If you activated kdb manually for diagnostic purposes, the system resumes normal functioning in whatever state it was when you activated kdb. In either case, if you enter the reboot command, the system restarts and normal operation resumes.
kdb is disabled by default and you must enter the kernel kdb command in global configuration mode to enable it. If kdb has been previously enabled, you can enter the no kernel kdb global configuration command to disable it. When kdb is enabled, you can activate it manually from the local console by pressing Ctrl-_ followed by Ctrl-B. On a vWAAS device, kdb can be enabled by pressing the Esc key and typing kdb.
The WAAS device is often unattended at many sites, and it is desirable for the WAAS device to automatically reboot after generating a core dump instead of requiring user intervention. Disabling the kernel debugger allows automatic recovery.
Examples
The following example shows how to enable, and then disable, access to the kernel debugger:
WAE(config)# kernel kdb
WAE(config)# no kernel kdb

For more information on Policy Class Map configuration mode commands, see the "Policy Map Configuration Mode Commands" section. To return to global configuration mode, enter the exit command.
You can delete a policy map by using the no form of this command.
The WAAS software comes with many class maps and policy rules that help your WAAS system classify and optimize some of the most common traffic on your network. Before you create a new class map or policy rule, we recommend that you review the default class map and policy rules and modify them as appropriate. It is usually easier to modify an existing class map or policy rule than to create a new one. For a list of the default applications, class maps, and policy rules, see the Cisco Wide Area Application Services Configuration Guide.
Note We strongly recommend that you use the WAAS Central Manager GUI to centrally configure policy maps for your WAAS devices. For more information, see the Cisco Wide Area Application Services Configuration Guide.
Examples
The following example shows how to configure a WAAS optimization policy map:
wae(config)# policy-map type waas myPolicy

no primary-interface {BVI bridge-id | GigabitEthernet slot/port | PortChannel index | Standby group-index | TenGigabitEthernet slot/port} [management]
Syntax Description
Defaults
The default primary interface is the Gigabit Ethernet 0/0 or 1/0 interface, depending on the hardware platform. If this interface is not configured, then the first operational interface on which a link beat is detected becomes the default primary interface. Interfaces with lower number IDs are polled first (for example, Gigabit Ethernet 1/0 is checked before 2/0). The Gigabit Ethernet interfaces are polled before the port-channel interfaces.
Command Modes
global configuration
Device Modes
application-accelerator
appnav-controller
central-manager
Usage Guidelines
You can change the primary interface without disabling the WAAS device. To change the primary interface, reenter the command string and specify a different interface.
Note If you use the restore factory-default preserve basic-config command, the configuration for the primary interface is not preserved. If you want to reenable the WAAS device after using the restore factory-default preserve basic-config command, make sure to reconfigure the primary interface after the factory defaults are restored.
Setting the primary interface to be a Standby group does not imply that Standby functionality is available. You must configure Standby interfaces using the interface standby global configuration command.
Examples
The following example shows how to specify the Gigabit Ethernet slot 1, port 0 as the primary interface on a WAAS device:
WAE(config)# primary-interface GigabitEthernet 1/0
The following example shows how to specify the Gigabit Ethernet slot 2, port 0 as the primary interface on a WAAS device:

Device Modes
application-accelerator
central-manager
Usage Guidelines
RADIUS authentication is disabled by default. You can enable RADIUS authentication and other authentication methods at the same time. You can also specify which method to use first. (See the (config) authentication configuration command.)
You can configure multiple RADIUS servers; authentication is attempted on the primary server first. If the primary server is unreachable, then authentication is attempted on the other servers in the RADIUS farm, in the order in which they were configured. If authentication fails for any reason other than a server is unreachable, authentication is not attempted on the other servers in the farm. This process applies regardless of the setting of the authentication fail-over server-unreachable command.
Examples
The following example shows how to specify a RADIUS server, specify the RADIUS key, and accept retransmit defaults. You can verify the configuration using the show radius-server command.
WAE(config)# radius-server host 172.16.90.121
WAE(config)# radius-server key myradiuskey

Syntax Description
Defaults
Distribution is enabled on an ANC. Pass-through offload is enabled for config, intermediate, and no-peer reasons.
Command Modes
global configuration
Device Modes
application-accelerator
appnav-controller
Usage Guidelines
Use the service-insertion command to configure the entities (WNs, WNGs, ANCs, an ANCG, and a service context) that are part of an AppNav Cluster. Some options of this command initiate configuration submodes, which are indicated by a different prompt (for example, config-scg). For more information on the configuration submode commands, see the following sections:
•service-context—"Service Context Configuration Mode Commands"
•appnav-controller-group—"AppNav Controller Group Configuration Mode Commands"
•service-node—"Service Node Configuration Mode Commands"
•service-node-group—"Service Node Group Configuration Mode Commands"
Within configuration submodes, you can use the various commands to define the settings of the entity. To return to global configuration mode, enter the exit command.
Each WN (and ANC acting as a WN) in the AppNav Cluster must be configured with WN settings by the service-insertion service-node command.
Each ANC in the AppNav Cluster must be configured with the following:
•ANCG settings by the service-insertion appnav-controller-group command
•WNG settings by the service-insertion service-node-group command
•Service context settings by the service-insertion service-context command
You can put an ANC into monitoring mode with the no service-insertion appnav-controller distribute enable command. This command stops the ANC from distributing any traffic to WNs for optimization. Instead, all traffic is passed through. This mode can be used for traffic monitoring for deployment sizing or troubleshooting purposes. If one ANC in an AppNav Cluster has this setting, all ANCs operate in monitor mode. You can reenable distribution with the service-insertion appnav-controller distribute enable command.
You can use the service-insertion pass-through offload enable command on a WN to prevent the ANCs from sending pass-through traffic to that WN. You can use this command on an ANC to prevent the ANC from sending pass-through traffic to any WN. The options allow you to specify what kind of pass-through traffic is to be off loaded by the ANC.
You may want to use the swap src-ip option if you are using a port channel for the cluster interface or there is a load balancing device between the ANC and WN. This option may improve the load balancing of traffic that the ANC distributes to WNs for optimization because it load balances based on the client IP address rather than the ANC IP address. (For traffic from the server to the client, it swaps the server IP address with the ANC IP address.) The Central Manager enables this feature automatically if any existing ANCs or WNs have port channel cluster interfaces that you configure with the Central Manager.
Examples
The following example shows how to configure and enable a WN:

Usage Guidelines
The DSCP field in an IP packet enables different levels of service to be assigned to network traffic. Levels of service are assigned by marking each packet on the network with a DSCP code. DSCP is the combination of IP Precedence and Type of Service (ToS) fields. For more information, see RFC 2474.
A DSCP value is assigned in a policy rule and applies to all traffic associated with a class map. If a DSCP value is not assigned or defined, the default DSCP value is applied to traffic. The global default DSCP value is copy, which copies the DSCP value from the incoming packet and uses it for the outgoing packet.
Table 3-2 lists the valid DSCP marking values that you can specify.
Examples
The following example shows how to set the default DSCP marking value to copy:
WAE(config)# service-policy type waas set ip dscp copy

v3 {auth [notify name] [read name] [write name] |
noauth [notify name] [read name] [write name] |
priv [notify name] [read name] [write name]}}
Syntax Description
Defaults
The default is that no user security model group is defined.
Command Modes
global configuration
Device Modes
application-accelerator
central-manager
Usage Guidelines
The maximum number of SNMP groups that can be created is 10.
Select one of three SNMP security model groups: Version 1 (v1) Security Model, Version 2c (v2c) Security Model, or the User Security Model (v3 or SNMPv3). Optionally, you then specify a notify, read, or write view for the group for the particular security model chosen. The v3 option allows you to specify the group using one of three security levels: auth (AuthNoPriv Security Level), noauth (noAuthNoPriv Security Level), or priv (AuthPriv Security Level).
Examples
The following example shows how to define a user security model group named acme that uses the SNMP version 1 security model and a view name of mymib for notifications:
WAE(config)# snmp-server group acme v1 notify mymib

Usage Guidelines
If you do not enter an snmp-server host command, no traps are sent. To configure the WAAS device to send SNMP traps, you must enter at least one snmp-server host command. To enable multiple hosts, you must enter a separate snmp-server host command for each host. The maximum number of snmp-server host commands is four.
When multiple snmp-server host commands are given for the same host, the community string in the last command is used.
The snmp-server host command is used with the snmp-server enable traps command to enable SNMP traps.
You must enable SNMP with the snmp-server community command.
Examples
The following example shows how to send the SNMP traps defined in RFC 1157 to the host specified by the IP address 172.16.2.160. The community string is comaccess:
WAE(config)# snmp-server enable traps

(config) sshd
To enable the SSH daemon on a WAAS device, use the sshd global configuration command. To disable the SSH daemon on a WAAS device, use the no form of this command.
sshd {allow-non-admin-users | enable | password-guesses number | timeout seconds }
no sshd {allow-non-admin-users | enable | password-guesses number | timeout seconds }
Syntax Description
Defaults
By default, the SSH daemon is disabled on a WAAS device. If you use the sshd enable command to enable the SSH daemon on a WAAS device, the following default settings are used:
password-guesses number: 3 guesses
timeout seconds: 300 seconds
version: ssh version 2 protocol is enabled
Note The SSH version 1 protocol is no longer supported. Only the SSH version 2 protocol is supported by the WAAS device.
Command Modes
global configuration
Device Modes
application-accelerator
central-manager
Usage Guidelines
Before you enable the sshd command, use the ssh-key-generate command to generate a private and a public host key, which the client uses to verify the server identity.
Although the sshd password-guesses command specifies the number of allowable password guesses from the SSH server side, the actual number of password guesses for an SSH login session is determined by the combined number of allowable password guesses of the SSH server and the SSH client. Some SSH clients limit the maximum number of allowable password guesses to three (or to one in some cases), even though SSH server side allows more than this number of guesses.
When you enter the sshd password-guesses command and specify n allowable password guesses, certain SSH clients interpret this number as n+1. For example, when configuring the number of guesses to two by issuing the command sshd password-guesses 2 for a particular device, SSH sessions from some SSH clients will allow three password guesses.
Note You can use the Telnet daemon with the WAAS device. SSH does not replace Telnet.
Examples
The following example shows how to enable and configure a Secure Shell daemon on the WAAS device:
WAE(config)#
sshd enable
WAE(config)#
sshd timeout 20
Related Commands
(config) ssh-key-generate
To generate the SSH host key for a WAAS device, use the ssh-key-generate global configuration command. To remove the SSH key, use the no form of this command.
ssh-key-generate [key-length length]
no ssh-key-generate [key-length length]
Syntax Description
key-length length |
(Optional) Configures the length of the SSH key. The number of bits is 512-2048. |
Defaults
key-length length: 1024 bits
Command Modes
global configuration
Device Modes
application-accelerator
central-manager
Usage Guidelines
Before you enter the sshd enable command, enter the ssh-key-generate command to generate a private and a public host key, which the client programs use to verify a server identity.
When you use an SSH client and log in to a WAAS device, the public key for the SSH daemon that is running on the device is recorded in the client machine known_hosts file in your home directory. If you regenerate the host key by specifying the number of bits in the key-length command option, you must delete the old public key entry associated with the WAAS device in the known_hosts file before running the SSH client program to log in to the WAAS device. When you use the SSH client program after deleting the old entry, the known_hosts file is updated with the new SSH public key for the WAAS device.
Examples
The following example shows how to generate an SSH public key and then enables the SSH daemon on the WAAS device:
WAE(config)#
ssh-key-generate
Ssh host key generated successfully
Saving the host key to box ...
Host key saved successfully
WAE(config)#
sshd enable

(config) tacacs
To configure TACACS+ server parameters on a WAAS device, use the tacacs global configuration command. To disable individual options, use the no form of this command.
tacacs {host {hostname | ip-address} [primary | port number] | key keyword | password ascii | retransmit retries | timeout seconds}
no tacacs {host {hostname | ip-address} | key keyword | password ascii | retransmit retries | timeout seconds}
Syntax Description
Defaults
port number: 49
keyword: none (empty string)
timeout seconds: 5
retries: 2
password: The default password type is PAP.
Command Modes
global configuration
Device Modes
application-accelerator
central-manager
Usage Guidelines
To enable user authentication with a TACACS+ server, use the authentication global configuration command. (See the (config) authentication configuration command.)
Note When AAA Command Authorization is enabled for a device through the Central Manager GUI, TACACS+ CLI configuration changes are not allowed and tacacs commands will fail.
You can use the TACACS+ remote database to maintain login and configuration privileges for administrative users. The tacacs host command allows you to configure the network parameters required to access the remote database.
Use the tacacs key command to specify the TACACS+ key, used to encrypt the packets transmitted to the server. This key must be the same as the one specified on the server daemon. The maximum number of characters in the key must not exceed 32 printable ASCII characters. An empty key string is the default. All leading spaces are ignored; spaces within and at the end of the key string are not ignored. Double quotes are not required even if there are spaces in the key.
Note If you configure a TACACS+ key on the WAAS device (the TACACS+ client), make sure that you configure an identical key on the external TACACS+ server. Do not use the following characters: backwards single quote (`), double quote ("), pipe (|), closing bracket (]), number sign (#), or backslash (\).
The tacacs timeout is the number of seconds that the WAAS device waits before declaring a timeout on a request to a particular TACACS+ server. The range is from 1 to 20 seconds, with 5 seconds as the default. The number of times that the WAAS device repeats a retry-timeout cycle before trying the next TACACS+ server is specified by the tacacs retransmit command. The default is two retry attempts.
Three unsuccessful login attempts are permitted. TACACS+ logins may appear to take more time than local logins depending on the number of TACACS+ servers and the configured timeout and retry values.
Use the tacacs password ascii command to specify the TACACS+ password type as ASCII. The default password type is PAP (Password Authentication Protocol).When the no tacacs password ascii command is used to disable the ASCII password type, the password type is once again reset to PAP.
If you do not use the primary keyword to specify the primary server, the primary server is the first one configured. If you remove the primary server by using the no tacacs host command, the first configured server (other than the removed server) becomes the primary server.
You can configure multiple TACACS+ servers; authentication is attempted on the primary server first. If the primary server is unreachable, then authentication is attempted on the other servers in the TACACS+, in the order in which they were configured. If authentication fails for any reason other than a server is unreachable, authentication is not attempted on the other servers in the farm. This process applies regardless of the setting of the authentication fail-over server-unreachable command.
Examples
The following example shows how to configure the key used in encrypting packets:
WAE(config)# tacacs key human789
The following example shows how to configure the host named spearhead as the primary TACACS+ server:
WAE(config)# tacacs host spearhead primary

The buffer should be equal to or greater than twice the Bandwidth Delay Product (BDP). The BDP is equivalent to the bandwidth (in bits per second) * latency (in seconds). For example, for a 45-Mbps link with a 150-ms (0.15 sec) round-trip delay, the BDP is 45 Mbps * 0.15 sec = 6.75 Mb, or 0.844 MB (844 KB). In this case, you could set the buffer size to 2000 KB.

Usage Guidelines
An asymmetric connection occurs if an ANC receives a SYN-ACK packet for which it does not have a flow state and for which no other ANC in the cluster has a flow state. This indicates a problem where the ANC is not intercepting both directions of the connection.
If the asymmetric connections threshold is exceeded during a one-minute interval, a "Total failed asymmetric flow queries has crossed threshold limit" alarm is raised. This alarm is cleared after the number of asymmetric flow learning failures drops below half of the configured threshold for five consecutive minutes. This threshold applies only to ANCs in an AppNav deployment.
The CIFS accelerator performs below the optimum level when certain resources are running low, if the find first requests are too many, or if there are too many open files.
These parameters can be monitored by setting thresholds. If the configured threshold for any CIFS application accelerator is exceeded on a WAE, the relevant threshold alarm is raised. The alarm is cleared when the relevant count falls to less than the configured threshold. The alarms are CIFS `Find First' Local Operation Above Threshold, CIFS `Find First' Remote Operation Above Threshold, CIFS Directory Resources Low, and CIFS `Open Files' Above Threshold.
The maximum value of the open-file count is platform dependent. For WAE 294, the maximum number of open files can be preconfigured to 500; for WAE 574, the maximum number is 1500; for WAE 674, the maximum number is 12000 and for WAE 7571, the maximum number of open files is 64000.
The system load percentage threshold refers to the percentage of connection capacity used for application accelerators and TFO connections on a WAE. If the configured load threshold for any application accelerator or TFO connections is exceeded on a WAE, the connection threshold exceeded alarm is raised. This alarm is cleared when the connection count falls to 10 percent less than the configured threshold (85 percent by default).
The CPU load threshold refers to the CPU load utilization on a WAE. When the average CPU utilization on the device exceeds the set threshold for 2 minutes, the device stops accepting new connections and passes any new connections through. When the average CPU utilization falls below the threshold for 2 minutes, the device resumes accepting optimized connections. You can disable CPU load monitoring by using the no form of the CPU enable command.
Examples
The following example shows how to configure an asymmetric connection threshold of 100,000:
WAE(config)# threshold-monitor appnav-controller asymmetric-flow-query-failure value 100
The following example shows how to configure an open files threshold of 500:
WAE-231-03(config)# threshold-monitor accelerator cifs open-files 500
The following example shows how to configure a system load threshold of 90 percent:
WAE(config)# threshold-monitor system load 90
