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

Command Modes

global configuration

Device Modes Default

application-accelerator

Usage Guidelines

OTT (Over the Top) Caching caches dynamic content by examining the URL related to a session and a site to determine if the object is identical to one previously stored in the CE cache.

OTT is used for streamed content, particularly video content, and for sites that use dynamic URLs based on session or authentication methods. Currently, the CE only uses OTT for one site, www.youtube.com.

Caution Though it is possible to enable OTT caching with this command, note that you must initially enable OTT from the WAAS CM, so that registration takes place and the activation file is loaded. Initially enabling OTT via the CLI would also invalidate the EULA.

Examples

The following example shows how to enable OTT caching:

WAAS(config)# accelerator http object-cache ott enable

Usage Guidelines

The Cisco Cloud Web Security feature provides content scanning of HTTP and secure HTTP/S traffic and malware protection service to web traffic. Cisco Cloud Web Security servers scan the web traffic content and either allow or block the traffic based on the configured policies. Servers use credentials such as private IP addresses, usernames, and user groups to identify and authenticate users and redirect the traffic for content scanning.

This command enables the same feature that is displayed on the WAAS Central Manager Advanced Cache Settings screen, as the Cisco Cloud Web Security present check box.

Examples

The following example shows how to enable the Cisco Cloud Web Security feature.

(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 | session-limit limit { always | none }}

Syntax Description

enable	Enables the ICA traffic accelerator.
exception	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.
wansecure-mode	Configures the state of WAN Secure mode.
session-limit limit	Sets the session limit for the ICA AO. The maximum value that can be set is the device TFO (Transport Flow Optimization) limit.
always	Enables WAN Secure mode for ICA.
none	Disables WAN Secure mode for ICA (default).

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 session-limit limit command to limit the number of session for the ICA AO (application accelerator).

Warning Make sure you have accurately measured the per ICA user bandwidth before changing the accelerator ica session-limit limit parameter. Failure to do so could lead to undesired overload scenarios.

Here are guidelines and limitations for the accelerator session-limit limit command:

You must enter this command when the ICA AO is running.
The new value takes effect only after the ICA AO is restarted.

Before an ICA AO restart, the show statistics accelerator output includes old and pending values for session limits counters; after an ICA AO restart, the output includes only new session limit values. Here is how the session limit counters are displayed for show statistics accelerator for each scenario:

– Before ICA AO restart—After you have entered a new session limit value, but before an ICA AO restart, the Connection Limit and Effective Limit counters will still show the old ICA session limit values. Another counter, New ICA Session Limit, shows the new (pending) value.

– After ICA AO restart—After you have entered a new session limit value, and after an ICA AO restart, the Connection Limit and Effective Limit counters will show the new ICA session limit value. The New ICA Session Limit counter is no longer needed, and is not included in the output.

The maximum value that can be set is the device TFO limit.
After you have saved the entered value to the startup configuration, the value is persistent across device reboots.

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

The following example shows how to set a session limit for the ICA application accelerator:

WAE(config)# accelerator ica session limit ?

default Set default session limit

WORD Session count (integer value)

WAE(config)# accelerator ica session limit 33

Setting session limit to 33. Changes will take effect after you restart ICA AO.

WARNING: Make sure you have accurately measured the per ICA user bandwidth before changing this parameter. Failure to do so could lead to undesired overload scenarios.

(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

enable	Enables the MAPI traffic accelerator.
encryption	Enables the acceleration of encrypted MAPI traffic.
read-opt	Enables the read-ahead optimization of the MAPI traffic for mail reading.
write-opt	Enables the asynchronous write optimization of the MAPI traffic for mail sending.
reserved-pool-size maximum-percent max_percent	Configures the maximum reserved connection pool percent, specified as the percent of the device TFO connection limit, to restrict the maximum connections reserved for MAPI optimization during TFO overload. Range is from 5 to 50. Default is 15.
wansecure-mode	Configures the state of WAN Secure mode.
always	Enables WAN Secure mode for encrypted MAPI acceleration.
auto	Enables WAN Secure mode for encrypted MAPI acceleration only if encrypted traffic is received.
none	Disables WAN Secure mode for encrypted MAPI acceleration.
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.

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

Note To ensure that each AO object cache and the global object cache function successfully, note these guidelines:

Each AO object cache can be enabled or disabled independent of whether or not the global object cache is enabled or disabled.
You must disable all individual AO object caches before you use the no object-cache enable global configuration command to disable the global object cache.
The object-cache enable global configuration command does not automatically enable individual AO object caches.
You can enable or disable an individual AO object cache whether or not the associated AO is enabled or disabled.

Command Modes

global configuration

Device Modes

application-accelerator

Usage Guidelines

The enterprise license is required to start the SMB accelerator.

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.

Use the object-cache enable command to enable disk caching of SMB traffic.

Use the accelerator smb signing unwrap enable command to verify signature of the signed request packets at the Edge WAE. This checks whether the packet is modified/tampered while coming over the LAN. However, since the packet usually travels in the LAN from the Client to the Edge WAE, chances of man-in-middle attacks are less likely and you may choose to disable Edge side signature verification for request packets.

Use the accelerator smb wansecure-mode always command to enable WAN Secure mode for optimizing signed SMBv2 traffic. The default is “always”. The WAN Secure mode configuration for both the EDGE WAE and Core WAEs must match (be set at “always”) in order for the SMB accelerator to optimize signed SMBv2 connections. Even if one side has “none” set, then the signed connections would be handed over for generic optimization.

Use the accelerator smb wansecure-mode none to disable the wansecure -mode.

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 SMB application accelerator:

WAE(config)# accelerator smb enable

The following example shows how to configure a case-insensitive regular expression that matches filenames to be bypassed for all optimizations:

WAE(config)# accelerator smb optimization bypass-pattern \\.pst|\\.accd[betr]

This configuration would bypass files that contain.pst,.accdb,.accde,.accdt, and.accdr (Outlook PST files, and MS Access files).

Syntax Description

clear 1-999

Specifies the number of alarms per second at which the alarm overload state on the WAAS device is cleared. When the alarm drops below this threshold, the alarm is cleared and the SNMP traps and alarm notifications are again sent to your NMS.

Note The alarm overload-detect clear value must be less than the alarm overload-detect raise value.

raise 10-1000

(Optional) Specifies the number of alarms per second at which the WAAS device enters an alarm overload state and SNMP traps and alarm notifications to your network management station (NMS) are suspended.

enable

Enables the detection of alarm overload situations.

Defaults

clear : 1 alarm per second

raise : 10 alarms per second

Command Modes

authentication { configuration { local | radius | tacacs | windows-domain }
enable [ primary | secondary | tertiary | quaternary ]

no authentication { configuration { local | radius | tacacs | windows-domain }
enable [ primary | secondary | tertiary | quaternary ]

Syntax Description

configuration	Sets the administrative login authorization (configuration) parameters for the WAAS device.
local	Selects the local database method for the WAAS device.
radius	Selects the RADIUS method for the WAAS device.
tacacs	Selects the TACACS+ method for the WAAS device.
windows-domain	Selects the Windows domain controller method for the WAAS device.
enable	Enables the specified methods for the WAAS device.
primary	(Optional) Specifies the first method that the WAAS device should use.
secondary	(Optional) Specifies the second method that the WAAS device should use.
tertiary	(Optional) Specifies the third method that the WAAS device should use if the primary and secondary methods fail.
quaternary	(Optional) Specifies the fourth method that the WAAS device should use if the primary, secondary, and tertiary methods all fail.

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.

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

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.

(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

blacklist	Specifies the TFO auto-discovery blacklist server configuration.
enable	Enables the TFO auto-discovery blacklist operation.
hold-time minutes	Specifies the maximum time to hold the blacklisted server address in the cache. The range is 1–10080 minutes. The default is 60 minutes.

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

(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

enable	Enables the automatic registration of devices using DHCP with the WAAS Central Manager.
FastEthernet slot/port	(Optional) Selects a Fast Ethernet interface for automatic registration using DHCP. Selects slot number and port number of the Fast Ethernet interface. Valid slot values depend on the hardware platform.
GigabitEthernet slot/port	(Optional) Selects a Gigabit Ethernet interface for automatic registration using DHCP. Selects slot number and port number of the Gigabit Ethernet interface. Valid slot values depend on the hardware platform.
TenGigabitEthernet slot/port	(Optional) Selects a TenGigabitEthernet interface for automatic registration using DHCP. Selects slot number and port number of the 10-Gigabit Ethernet interface. Valid slot values depend on the hardware platform.
preserve-ip	(Optional) Converts a dynamic IP address to a static IP address when you remove the automatic registration from an interface so that the interface remains configured with an IP address.

Defaults

Automatic registration using DHCP is enabled on a WAE by default.

Command Modes

global configuration

Device Modes

application-accelerator

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

message text	(Optional) Specifies a message to be displayed when an EXEC process is created. The message text is on a single line (980 characters maximum). The WAE translates the \n portion of the message to a new line when the banner is displayed to the user.

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:

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.

Command Modes

global configuration

Device Modes

application-accelerator

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:

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.

Are you sure want to enable [yes/no]?

To configure traffic interception with an access list, use the interception global configuration command. To disable the interception access list, use the no form of this command.

interception access-list { acl-num | acl_name }

no interception access-list { acl-num | acl_name }

Syntax Description

acl_num	Numeric identifier that identifies the ACL to apply to traffic interception. For standard ACLs, the valid range is 1–99; for extended ACLs, the valid range is 100–199.
acl_name	Alphanumeric identifier of up to 30 characters, beginning with a letter that identifies the ACL to apply to traffic interception.

Defaults

No default behaviors or values.

Command Modes

global configuration

Device Modes

application-accelerator

central-manager

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.

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

Usage Guidelines

You must use the interception-method command to enable a traffic interception method before configuring other traffic interception settings. Other settings that are specific to a particular traffic interception method are not available until after you use this command to enable the method.

When you are changing the traffic interception method, all configuration settings for the current method are removed before the new method is enabled. You are prompted to confirm before the command proceeds.

Examples

The following example shows how to enable WCCP interception:

dc-wae(config)# interception-method wccp

Inline interception method will be removed. Proceed?[yes]: yes

Command Modes

global configuration

Device Modes

application-accelerator

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 and standby 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

The following example shows that an interface can be configured in a sequence of CLI commands:

WAE(config)# interface GigabitEthernet 1/0

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..

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).

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. 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)# exit

The following example shows how to remove a port-channel interface:

WAE(config)# interface PortChannel 1

WAE(config-if)# no ip address 10.10.10.10 255.0.0.0

WAE(config-if)# exit

WAE(config)# no interface PortChannel 1

Usage Guidelines

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.

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

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.

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

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:

WAE(config)# interface TenGigabitEthernet 1/0

WAE(config-if)# ip access-group 1 in

WAE(config-if)# exit

The following example shows how to enable a shut down interface:

WAE(config)# no interface TenGigabitEthernet 1/0 shutdown

The following example shows how to add an interface to a channel group:

WAE# configure

WAE(config)# interface TenGigabitEthernet 1/0

WAE(config-if)# channel-group 1

WAE(config-if)# exit

The following example shows how to remove an interface from a channel group:

WAE(config)# interface TenGigabitEthernet 1/0

WAE(config-if)# no channel-group 1

WAE(config-if)# exit

The following example shows how to assign a secondary IP address on a TenGigabitEthernet interface:

WAE# configure

WAE(config)# interface TenGigabitEthernet 1/0

WAE(config-if)# ip address 10.10.10.10 255.0.0.0 secondary

The following example shows how to configure a description for a TenGigabitEthernet interface:

Usage Guidelines

To display the interface identifiers (for example, interface virtual 1/0), use the show running-config or show startup-config commands.

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 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.

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

After you define the description for an interface, use the show EXEC commands to display the defined interface descriptions. Enter the show interface virtual EXEC command to display the defined description for a virtual interface on the WAE.

Examples

The following example shows how to assign a secondary IP address on a virtual interface on a vWAAS device:

WAE# configure

Defaults

No default behavior or values.

Command Modes

global configuration

Device Modes

application-accelerator

central-manager. (Management interface commands are not available when device is on central manager mode)

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 three 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:

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

Related Commands

To enable the generation of Internet Control Message Protocol (ICMP) unreachable messages, use the ip unreachables df command in global configuration mode. To disable this function, use the no form of this command.

ip unreachables df

no ip unreachables df

Syntax Description

df	Limits the rate ICMP destination unreachable messages are sent when Type 3 code 4, destination unreachable, don't fragment (DF) bit sent and fragmentation required, is specified in the IP header of the ICMP destination unreachable message.

Defaults

The default value is one ICMP destination unreachable message per 500 microseconds.

Command Modes

global configuration

Device Modes

application-accelerator

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.

ExamplesExamples

The following example enables the generation of ICMP unreachable messages, as appropriate, on an interface:

WAE(config)# interface ethernet 0

WAE(config)# ip unreachables df

ipv6 {default-gateway [ management ] ip-v6 address | route [ management ] ip-v6 address}

no ipv6 {default-gateway [ management ] ip-v6 address | route [ management ] ip-v6 address}

Syntax Description

default-gateway ip-address	Specifies the IPv6 address of the default gateway, in the X:X:X:X format.
route ip-v6 address	Specifies the net route and the IPv6 address.
management	Specifies that the default gateway or net route is for the management interface.

Defaults

No default behavior or values.

Command Modes

global configuration

Device Modes

application-accelerator

central-manager

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. The WAAS device uses the default gateway to route IP packets when there is no specific route found to the destination. To remove the IP default gateway, use the no form of this command.

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.If you have designated a management interface, you can configure a different ip route for the management interface by using the management keyword.

To configure static IP routing, use the ip route command. To remove the route, use the no form of this command.

Examples

The following example shows how to configure a default gateway for the WAAS device:

WAE(config)# ipv6 default-gateway 2013:1:1:10::1

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)# ipv6 default-gateway management 2013:1:2:10::1

The following example shows how to configure a static IP route for the WAAS device:

WAE(config)# ipv6 route 2000:2:3:4::6/128 2013:1:1:10::1

(config) kerberos

To authenticate a user that is defined in the Kerberos database, use the kerberos global configuration command. To disable authentication, use the no form of this command.

kerberos {dns}

no kerberos {dns}

Syntax Description

dns

Enables or disables DNS lookup for Kerberos.

Defaults

kerberos-realm: NULL string

port-number: 88

Command Modes

global configuration

Device Modes

application-accelerator

central-manager

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

WAE(config)# kerberos server wae.abc.com 10.10.192.50

WAE(config)# exit

WAE# show kerberos

Kerberos Configuration:

-----------------------

Local Realm: WAE.ABC.COM

(config) kernel kdb

To enable access to the kernel debugger (kdb), use the kernel kdb global configuration command. To disable access to the kernel debugger, use the no form of this command.

kernel kdb

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:

primary-interface virtual slot/port {IPv4 | IPv6}[ management ]

no primary-interface virtual slot/port {IPv4 | IPv6}[ management ]

Syntax Description

GigabitEthernet slot/port	Selects a Gigabit Ethernet interface as the primary interface of the WAAS device. Valid slot and port values depend on the hardware platform.
PortChannel index	Selects a port channel interface as the primary interface of the WAAS device. Specify the port channel index number (1–4).
Standby group-index	Selects a standby group as the primary interface of the WAAS device. Specify the standby group number (1–3).
TenGigabitEthernet slot/port	Selects a TenGigabitEthernet interface as the primary interface of the WAAS device. Valid slot and port values depend on the hardware platform.

IPv6	Configures interface or IPv6 traffic.
management	Designates the specified interface for management traffic.
virtual	Selects the virtual interface as the primary interface. Specify the slot range (1–2) and the port range as 0.

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

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, for IPv6 traffic, on a WAAS device:

WAE(config)# primary-interface GigabitEthernet 1/0 IPv6

The following example shows how to specify the Gigabit Ethernet slot 2, port 0 as the primary interface on a WAAS device:

WAE(config)# primary-interface GigabitEthernet 2/0 IPv6

The following example shows how to specify port channel interface 1 as the primary interface on a WAAS device:

WAE(config)# primary-interface portchannel 1 IPv6

The following example shows how to specify the Gigabit Ethernet slot 1, port 0 as the primary interface, for IPv6 traffic, on a WAAS device and designate it to be used for management trafffic:

WAE(config)# primary-interface GigabitEthernet 1/0 IPv6 management

To configure a primary interface to be used as a management interface, you should have configured it with an ip and default-gateway address.

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.

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.

Table 3-2 DSCP Marking Values
DSCP Code	Description
0 - 63	Marks packets with a numeric dscp from 0 to 63.
af11	Marks packets with AF11 dscp (001010).
af12	Marks packets with AF11 dscp (001100).
af13	Marks packets with AF13 dscp (001110).
af21	Marks packets with AF21 dscp (010010).
af22	Marks packets with AF22 dscp (010100).
af23	Marks packets with AF23 dscp (010110).
af31	Marks packets with AF31 dscp (011010).
af32	Marks packets with AF32 dscp (011100).
af33	Marks packets with AF33 dscp (011110).
af41	Marks packets with AF41 dscp (100010).
af42	Marks packets with AF42 dscp (100100).
af43	Marks packets with AF43 dscp (100110).
cs1	Marks packets with CS1 (precedence 1) dscp (001000).
cs2	Marks packets with CS2 (precedence 2) dscp (010000).
cs3	Marks packets with CS3 (precedence 3) dscp (011000).
cs4	Marks packets with CS4 (precedence 4) dscp (100000).
cs5	Marks packets with CS5 (precedence 5) dscp (101000).
cs6	Marks packets with CS6 (precedence 6) dscp (110000).
cs7	Marks packets with CS7 (precedence 7) dscp (111000).
copy	Copies the DSCP value from the incoming packet to the outgoing packet. (default)
default	Marks packets with default dscp (000000).

Usage Guidelines

In the WAAS software the following six generic alarm traps are available in the CISCO-CONTENT-ENGINE-MIB:

Name of Alarm Trap	Severity	Action
cceAlarmCriticalRaised	Critical	Raised
cceAlarmCriticalCleared	Critical	Cleared
cceAlarmMajorRaised	Major	Raised
cceAlarmMajorCleared	Major	Cleared
cceAlarmMinorRaised	Minor	Raised
cceAlarmMinorCleared	Minor	Cleared

Note By default, these six general alarm traps are disabled.

These six general alarm traps provide SNMP and Node Health Manager integration. You can enable or disable each of these six alarm traps through the WAAS CLI.

To configure traps, you must enter the snmp-server enable traps command. If you do not enter the snmp-server enable traps command, no traps are sent.

The snmp-server enable traps command is used with the snmp-server host command. Use the snmp-server host command to specify which host or hosts receive SNMP traps. To send traps, you must configure at least one host using the snmp-server host command.

To allow a host to receive a trap, you must enable both the snmp-server enable traps command and the snmp-server host command for that host.

You must enable SNMP with the snmp-server community command.

To disable the sending of the MIB-II SNMP authentication trap, you must enter the command no snmp-server enable traps snmp authentication.

Examples

The following example shows how to enable the WAAS device to send all traps to the host 172.31.2.160 using the community string public:

WAE(config)# snmp-server enable traps

WAE(config)# snmp-server host 172.31.2.160 public

The following example shows how to disable all traps:

WAE(config)# no snmp-server enable traps

central-manager

Usage Guidelines

Using the snmp-server trigger global configuration command, you can define additional SNMP traps for other MIB objects of interest to your particular configuration. You can select any MIB object from any of the support MIBs for your trap. The trap can be triggered based on a variety of tests:

absent—A specified MIB object that was present at the last sampling is no longer present as of the current sampling.
equal—The value of the specified MIB object is equal to the specified threshold.
greater-than—The value of the specified MIB object is greater than the specified threshold value.
less-than—The value of the specified MIB object is less than the specified threshold value.
on-change—The value of the specified MIB object has changed since the last sampling.
present—A specified MIB object is present as of the current sampling that was not present at the previous sampling.
threshold- Min value and Max values specifying the lower and upper thresholds.

The threshold value can be based on an absolute sample type or on a delta sample type. An absolute sample type is one in which the test is evaluated against a fixed integer value between zero and 4294967295. A delta sample type is one in which the test is evaluated against the change in the MIB object value between the current sampling and the previous sampling.

After you configure SNMP traps, you must use the snmp-server enable traps event global configuration command for the event traps you just created to be generated. To save the MIB data using the write mib-data EXEC command.

Note You can create valid triggers only on read-write and read-only MIB objects. If you try to create a trigger on a read-create MIB object, you receive an error message.

Examples

The following example shows how to create a threshold for the MIB object esConTabIsConnected so that a trap is sent when the connection from the Edge WAE to the Core WAE is lost:

WAE(config)# snmp-server trigName esConTabIsConnected ?

<60-600> The number of seconds to wait between trigger sample

wildcard Option to treat the MIB variable as wildcarded

WAE(config)# snmp-server trigName esConTabIsConnected wildcard 600 ?

absent Absent existence test

equal Equality threshold test

greater-than Greater-than threshold test

less-than Less-than threshold test

on-change Changed existence test

present Present present test

threshold Threshold test

WAE(config)# snmp-server trigName esConTabIsConnected wildcard 600 less-than?

absolute Absolute sample type

delta Delta sample type

(config) snmp-server user

To define a user who can access the SNMP server, use the snmp-server user global configuration command. To remove access, use the no form of this command.

snmp-server user name group
[ auth { md5 password [ priv password ] |
sha password [ priv password ]} |
remote octetstring [ auth { md5 password [ priv password ] |
sha password [ priv password ]}]]

no nmp-server user name group
[ auth { md5 password [ priv password ] |
sha password [ priv password ]} |
remote octetstring [ auth { md5 password [ priv password ] |
sha password [ priv password ]}]]

Syntax Description

name group	Name and group of the SNMP user. Use letters, numbers, dashes, and underscores, but no blanks. The name specifies the user on the SNMP host who wants to communicate with the SNMP agent on the WAAS device. You can enter a maximum of 32 characters for the name. The group specifies the group to which the SNMP user belongs. You can enter a maximum of 64 characters for the group.
auth	(Optional) Configures user authentication parameters.
md5 password	Configures HMAC MD5 user authentication password.
priv password	(Optional) Alphanumeric string (256 characters maximum) that configures the authentication HMAC-MD5 user private password. The following special characters are not supported: space, backwards single quote (`), double quote ("), pipe (\|), or question mark (?). Note For SNMPv3 users using WAAS Software Version 6.x and later, the private password must be a minimum of 8 alphanumeric characters and a maximum of 256 alphanumeric characters.
sha password	Configures the HMAC-SHA authentication password. You can enter a maximum of 256 characters.
remote octetstring	(Optional) Specifies the globally unique identifier (engineID) for a remote SNMP entity (for example, the SNMP network management station) for at least one of the SNMP users (10 to 64 characters, not counting colons). To send an SNMPv3 inform message, you must configure at least one SNMPv3 user with a remote SNMP ID option on the WAAS device. The SNMP ID is entered in octet string form. For example, if the IP address of a remote SNMP entity is 192.147.142.129, then the octet string would be 00:00:63:00:00:00:a1:c0:93:8e:81. (Colons will be removed in the show running-config command output.)

Related Commands

ssh

(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

allow-non-admin-users	Allows nonadministrative users to gain SSH access to the chosen device (or device group). By default, this option is disabled. Note Nonadministrative users are nonsuperuser administrators. All nonsuperuser administrators have restricted access to a WAAS device because their login accounts have a privilege level of 0. Superuser administrators have full access to a WAAS device because their login accounts have the highest level of privileges, a privilege level of 15.
enable	Enables the SSH daemon on a WAAS device.
password-guesses number	Specifies the maximum number of allowable password guesses per connection (1–3). The default is 3.
timeout seconds	Configures the number of seconds for which an SSH session will be active during the negotiation (authentication) phase between the client and server before it times out. The SSH login grace time value in seconds is 1–99999. The default is 300. If you have established an SSH connection to the WAAS device but have not entered the username when prompted at the login prompt, the connection will be terminated by the WAAS device if the grace period expires even after a successful login.

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

(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 768–2048.

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 key-length 860

Ssh host key generated successfully

Saving the host key to box...

Host key saved successfully

WAE(config)# sshd enable

Usage Guidelines

This command is available only on the following platforms: WAVE-294/594/694/7541/7571/8541, and vWAAS. This command changes the MTU setting for all interfaces on the device, including logical interfaces with at least one physical member, and may cause current active connections to time out. After you change the MTU using this command, you cannot change the MTU of individual interfaces.

Examples

The following example shows how to configure a jumbo MTU:

WAE(config)# system jumbomtu 9000

Changing system mtu setting will change the MTU values on all the interfaces. This may cause the current active connections in the device to timeout.

no tacacs { host { hostname | ip-address | ipv6 {ipv6-address} } [ primary | port number ] | key keyword | password ascii | retransmit retries | timeout seconds }

Syntax Description

host	Specifies a server address.
hostname	Hostname of the TACACS+ server.
ip-address	IP address of the TACACS+ server.
ipv6	IPv6 address of the TACACS+ server.
primary	(Optional) Sets the server as the primary server.
port number	Sets the port number of the TACACS+ server. If not specified, the default port 49 is used.
key keyword	Sets the security word. An empty string is the default.
password ascii	Specifies ASCII as the TACACS+ password type.
retransmit retries	Sets the number of times that requests are retransmitted to a server. The number of retry attempts allowed is 1–3. The default is 2 retry attempts.
timeout seconds	Sets the number of seconds to wait before a request to a server is timed out. The timeout is in seconds (1–20). The default is 5 seconds.

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 following example shows how to set the timeout interval for the TACACS+ server:

WAE(config)# tacacs timeout 10

The following example shows how to set the number of times that authentication requests are retried (retransmitted) after a timeout:

WAE(config)# tacacs retransmit 5

The following example shows the password type to be PAP by default:

WAE# show tacacs

(config) threshold-monitor

To configure monitoring thresholds, use the threshold-monitor global configuration command. To restore default settings, use the no form of this command.

threshold-monitor {system {load { load monitoring threshold percent } | cpu { higher threshold percentage | lower threshold percentage | win size size | sampling intervals interval} | enable }}

no threshold-monitor { system {load load monitoring threshold percent | cpu { higher threshold percentage | lower threshold percentage | win size size | sampling intervals interval} | enable }}

Syntax Description

system load	Sets the system load threshold to the specified percentage (80–100) of rated connection capacity.
cpu	Configures the threshold value for CPU load monitoring.
cpu utilization higher threshold percent	Sets the high threshold percentage (80-100) above which the system goes into the overloaded state when it is normal. But in the overloaded state, it doesn't go back to the normal state until the CPU utilization goes below the low threshold. The default CPU high threshold is 95 percent.
cpu utilization lower threshold percent	Sets the low threshold percentage (80-100) below which the system goes into the normal state when it is overloaded. This value has to be lower than the high threshold. The default CPU lower threshold is 90 percent.
win-size size	Configures the sampling window size for the moving average. It is the number of the most recent CPU utilization samples taken in calculating the latest CPU utilization percentage. The result is the average of the given number of samples.
sampling-intervals interval	Configures the sampling rate for the normal state and the overloaded state.
enable	Enables CPU load monitoring.

Defaults

The system load percentage is 95 percent of rated connection capacity for the device.

The CPU load percentage is 95 percent of the total CPU usage.

Usage Guidelines

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 a system load threshold of 90 percent:

WAE(config)# threshold-monitor system load 90
