Chapter: Using the WAAS Command-Line Interface

Using the WAAS Command-Line Interface

This chapter describes how to use the WAAS CLI, including an explanation of CLI command modes, navigation and editing features, and help features.

This chapter includes the following sections:

About the WAAS

The Cisco WAAS software command-line interface (CLI) is used in combination with the WAAS Manager GUI to configure, monitor, and maintain a WAAS device. The CLI on a WAAS device can be accessed directly through the console port of an attached PC or remotely through a Telnet session on a PC running terminal emulation software.

Noteblank.gif The WAAS software runs on a variety of WAE and WAVE appliances, WAE-NME and SM-SRE network modules, and as a virtual WAAS appliance (vWAAS).

Throughout this book, the term WAAS device refers collectively to a WAAS Central Manager and a WAE. The term WAE refers collectively to the supported platforms that are running the WAAS software unless otherwise noted.

Command Line Interface

The WAAS CLI allows you to configure, manage, and monitor WAAS devices on a per-device basis through a console connection or a terminal emulation program. The WAAS CLI also allows you to configure certain features that are only supported through the WAAS CLI (for example, configuring LDAP signing on a WAE).

The instructions and examples in this guide describe only those features that can be configured on an individual WAAS device using the WAAS CLI.

Graphical User Interface

In addition to the WAAS CLI, there are two WAAS graphical user interfaces (GUIs) that you access from your browser:

  • The WAAS Central Manager GUI allows you to centrally configure, manage, and monitor a WAE or group of WAEs that are registered with the WAAS Central Manager. You also use this GUI to configure, manage, and monitor the WAAS Central Manager, which is the dedicated appliance on which the WAAS Central Manager GUI is running.
note.gif

Noteblank.gif When you use the WAAS Central Manager GUI, you have the added capability of centrally configuring settings and policies for groups of WAEs (device groups). When you use the WAAS CLI, you can only configure settings and policies on a per-device basis.

The WAAS GUIs are the primary resources for configuration and monitoring WAEs. We strongly recommend that you use the WAAS Central Manager GUI instead of the WAAS CLI, whenever possible. For more information about how to use the WAAS GUIs to configure, manage, and monitor your WAAS devices, see the Cisco Wide Area Application Services Configuration Guide.

We recommend that you be familiar with the basic concepts and terminology used in internetworking, in your network topology, and in the protocols that the devices in your network can use. We also recommend that you have a working knowledge of the operating systems on which you are running your WAAS network, such as Microsoft Windows, Linux, or Solaris. This guide is not a tutorial.

Using Command Modes

The CLI for WAAS software is similar to the CLI for Cisco IOS software. Like Cisco IOS software, the WAAS CLI is organized into different command and configuration modes. Each mode provides access to a specific set of commands. This section describes the command modes provided by the WAAS software CLI and includes the following topics:

Organization of the WAAS CLI

The WAAS software CLI is organized into multiple command modes. Each command mode has its own set of commands that allow you to configure, maintain, and monitor a WAAS Wide Area Application Engine (WAE). The commands available to you at any given time depend on the mode you are in. You can enter a question mark (?) at the system prompt to obtain a list of commands available for each command mode.

The WAAS command modes include the following:

  • EXEC mode—Sets, views, and tests system operations. This mode is divided into two access levels: user and privileged. To use the privileged access level, enter the enable command at the user access level prompt, and then enter the privileged EXEC password when you see the password prompt.
  • Global configuration mode—Sets, views, and tests the configuration of WAAS software features for the entire device. To use this mode, enter the configure command from privileged EXEC mode.
  • Interface configuration mode—Sets, views, and tests the configuration of a specific interface. To use this mode, enter the interface command from global configuration mode.
  • Standard ACL configuration mode—Creates and modifies standard access lists on a WAAS device for controlling access to interfaces or applications. To use this mode, enter the ip access-list standard command from global configuration mode.
  • Extended ACL configuration mode—Creates and modifies extended access lists on a WAAS device for controlling access to interfaces or applications. To use this mode, enter the ip access-list extended command.
  • PKI certificate authority configuration mode—Configures public key infrastructure (PKI) encryption certificate authorities on a WAAS device. To use this mode, enter the crypto pki ca command.
  • PKI global settings configuration mode—Configures OCSP and revocation checking on a WAAS device. To use this mode, enter the crypto pki global-settings command.
  • SSL accelerated service configuration mode—Enables and configures secure socket layer (SSL) acceleration on your WAAS system. To use this mode, enter the crypto ssl service accelerated-service command.
  • SSL cipher list configuration mode—Configures SSL encryption cipher lists on a WAAS device. To use this mode, enter the crypto ssl cipher-list command.
  • SSL global service configuration mode—Enables and configures basic SSL acceleration settings on your WAAS system. To use this mode, enter the crypto ssl services global-settings command.
  • SSL host peering service configuration mode—Configures SSL encryption peering services on a WAAS device. To use this mode, enter the crypto ssl services host-service peering command.
  • SSL management service configuration mode—Configures SSL encryption management service parameters on a WAAS device. To use this mode, enter the crypto ssl management-service command.
  • WCCP configuration mode—Configures WCCP service parameters on a WAAS device. To use this mode, enter the wccp tcp-promiscuous command.
  • AppNav Controller Group configuration mode—Configures an AppNav Controller Group that is part of an AppNav Cluster. To use this mode, enter the service-insertion appnav-controller-group command.
  • Service Node Group configuration mode—Configures a WAAS Node Group that is part of an AppNav Cluster. To use this mode, enter the service-insertion service-node-group command.
  • Service Node configuration mode—Configures a WAAS Node that is part of an AppNav Cluster. To use this mode, enter the service-insertion service-node command.
  • Service Context configuration mode—Configures a service context for an AppNav Cluster. To use this mode, enter the service-insertion service-context command.
  • Class Map configuration mode—Configures an AppNav or optimization class map. To use this mode, enter the class-map command.
  • Policy Map configuration mode—Configures an AppNav or optimization policy map. To use this mode, enter the policy-map command.
  • Policy Class Map configuration mode—Configures a service policy in an AppNav or optimization policy map. To use this mode, enter the class command from Policy Map configuration mode.

Modes are accessed in this order: user EXEC mode, privileged EXEC mode, then global configuration mode. From global configuration mode, you can access the configuration submodes.

Using EXEC Mode

Use the EXEC mode to set, view, and test system operations. The user EXEC commands allow you to connect to remote devices, change terminal line settings on a temporary basis, perform basic tests, and list system information.

Most EXEC mode commands are one-time commands, such as show or more commands, which show the current configuration status, and clear commands, which clear counters or interfaces. EXEC mode commands are not saved across reboots of the WAE.

EXEC Mode Levels

The EXEC mode is divided into two access levels: user and privileged. The user EXEC mode is used by local and general system administrators, while the privileged EXEC mode is used by the root administrator. Use the enable and disable commands to switch between the two levels.

  • User level—Access to the user-level EXEC command line requires a valid password. The user-level EXEC commands are a subset of the privileged-level EXEC commands. The user-level EXEC prompt is the hostname followed by a right angle bracket (>). You can change the hostname using the hostname global configuration command.
  • Privileged level—The prompt for the privileged-level EXEC command line is the pound sign (#). To execute an EXEC command, enter the command at the EXEC system prompt and press the Return key. The following example shows how to access the privileged-level EXEC command line from the user level:
WAE> enable
WAE#
 

EXEC Mode Command-Line Processing

Common functions you can use when entering commands in EXEC mode include the following:

  • Edit—To edit commands, use the Delete or Backspace keys when you enter commands at the EXEC prompt.
  • Abbreviate—As a shortcut, you can abbreviate commands to the fewest letters that make them unique. For example, the letters sho can be entered for the show command.
  • Display multiple pages—Certain EXEC commands display multiple screens with the following prompt at the bottom of the screen:
--More--
 

Press the Spacebar to continue the output, or press Return to display the next line. Press any other key to return to the prompt. Also, at the --More-- prompt, you can enter a ? to display the help message.

  • Exit—To leave EXEC mode, use the exit command at the system prompt:
WAE# exit
WAE>
 
  • Comment—Any command line that begins with an exclaimation point (!) is considered a comment and is ignored.

Using Global Configuration Mode

Use global configuration mode to set, view, and test the configuration of WAAS software features for the entire device. To enter this mode, enter the configure command from privileged EXEC mode. The prompt for global configuration mode consists of the hostname of the WAE followed by (config) and the pound sign (#). You must be in global configuration mode to enter global configuration commands.

WAE# configure
WAE(config)#
 

Commands entered in global configuration mode update the running configuration file as soon as they are entered. These changes are not saved into the startup configuration file until you enter the copy running-config startup-config EXEC mode command. See the “Saving Configuration Changes” section. Once the configuration is saved, it is maintained across WAE reboots.

Configuration changes that you make in global configuration mode on a WAE are propagated to the Centralized Management System (CMS) database on the WAAS Central Manager. CLI changes are sent to the Central Manager after you exit out of configuration mode, or if all configuration mode sessions have been inactive for 10 minutes.

You must be in global configuration mode to enter specific subordinate configuration modes.

Configuration Submodes

Configuration submodes are used for the configuration of specific features within the scope of a given configuration mode. From global configuration mode, you can enter the following configuration submodes:

  • Interface configuration mode
  • Standard ACL configuration mode
  • Extended ACL configuration mode
  • PKI certificate authority configuration mode
  • PKI global settings configuration mode
  • SSL accelerated service configuration mode
  • SSL cipher list configuration mode
  • SSL global service configuration mode
  • SSL host peering service configuration mode
  • SSL management service configuration mode
  • WCCP configuration mode
  • AppNav Controller Group configuration mode
  • Service Node Group configuration mode
  • Service Node configuration mode
  • Service Context configuration mode
  • Class Map configuration mode
  • Policy Map configuration mode
  • Policy Class Map configuration mode

Exiting Configuration Mode

Common functions used in configuration modes include the following:

  • Exit current mode—To exit global configuration mode or any subordinate configuration mode, use the exit command or Ctrl-Z.
  • Exit to privileged EXEC mode—To exit to privileged EXEC mode from global configuration mode or any subordinate configuration mode, use the end global configuration command:
WAE(config)# end
WAE#
 

Using Interface Configuration Mode

Use interface configuration mode to set, view, and test the configuration of WAAS software features on a specific interface. To enter this mode, enter the interface command from the global configuration mode. The following example shows how to enter interface configuration mode:

WAE# configure
WAE(config)# interface ?
GigabitEthernet Select a gigabit ethernet interface to configure
InlineGroup Select an inline group interface to configure
PortChannel Ethernet Channel of interfaces
Standby Standby groups
 
WAE(config)# interface gigabitethernet ?
<1-2>/ GigabitEthernet slot/port

Device Mode

The WAAS software allows you to specify the device mode of a WAAS device. In a WAAS network, you must deploy a WAAS device in one of the following device modes:

  • WAAS Central Manager mode—Mode that the WAAS Central Manager uses.
  • WAAS application accelerator mode—Mode that a WAAS Accelerator (data center WAEs and branch WAEs that run the WAAS software) uses to optimize and accelerate traffic. (default)
  • WAAS AppNav Controller mode—Mode for a WAAS device that is operating as an AppNav Controller (ANC) that is intercepting and distributing traffic to other WAAS devices operating in application accelerator mode.

The set of WAAS CLI commands that are available vary based on the device mode of the WAAS device.

Changing the Device Mode

To change the device mode of a WAAS device, use the device mode global configuration command as follows:

waas-cm(config)# device mode ?
application-accelerator Configure device to function as a WAAS Engine.
central-manager Configure device to function as a WAAS Central Manager.
 

For example, after you use the WAAS CLI to specify the basic network parameters for the designated WAAS Central Manager (the WAAS device named waas-cm) and assign it as a primary interface, you can use the device mode configuration command to specify its device mode as central-manager.

waas-cm# configure
waas-cm(config)#
waas-cm(config)# primary-interface gigabitEthernet 1/0
waas-cm(config)# device mode central-manager
waas-cm(config)# exit
waas-cm# copy run start
waas-cm# reload
Proceed with reload?[confirm] y
Shutting down all services, will Reload requested by CLI@ttyS0.
Restarting system.
 

To display the current mode that the WAAS device is operating in, enter the show device-mode current EXEC command:

WAE# show device-mode current
Current device mode: application-accelerator
 

Displaying the Configured Device Mode

You can display the configured device mode for a change that has not taken effect by using the show device-mode configured EXEC command.

For example, if you changed the device mode to central-manager on a WAAS device (using the device mode central-manager global configuration command), but did not save the running configuration (using the copy run start EXEC command) then, even though the new device mode has not taken effect, the output for the show device-mode configured command would indicate that the configured device mode is central-manager:

WAE# show device-mode configured
Configured device mode: central-manager
 

Using Command-Line Processing

Cisco WAAS software commands are not case sensitive. You can abbreviate commands and parameters as long as they contain enough letters to be different from any other currently available commands or parameters.

You can also scroll through the last 20 commands stored in the history buffer and enter or edit the command at the prompt. Table 1-2 lists and describes the function performed by the available WAAS command-line processing options.

Checking Command Syntax

The caret symbol (^) indicates that you have entered an incorrect command, keyword, or argument at a specific point in the command string.

To set the clock, for example, you can use context-sensitive help to check the syntax for setting the clock.

WAE# clock 1222
^
%Invalid input detected at ‘^’ marker.
WAE# clock ?
read-calendar Read the calendar and update system clock
set Set the time and date
update-calendar Update the calendar with system clock
 

The help output shows that the set keyword is required. You can then check the syntax for entering the time.

WAE# clock set ?
<0-23>: Current Time (hh:mm:ss)
 

Enter the current time in 24-hour format with hours, minutes, and seconds separated by colons.

WAE# clock set 13:32:00
% Incomplete command.
 

The system indicates that you need to provide additional arguments to complete the command. Press the Up Arrow to automatically repeat the previous command entry, and then add a space and question mark (?) to display the additional arguments.

WAE# clock set 13:32:00 ?
<1-31> Day of the month
april
august
december
february
january Month of the Year
july
june
march
may
november
october
september
 

Enter the day and month as prompted, and use the question mark for additional instructions.

WAE# clock set 13:32:00 23 December ?
<1993-2035> Year
 

Now you can complete the command entry by entering the year.

WAE# clock set 13:32:00 23 December 05
^
%Invalid input detected at '^' marker.
WAE#
 

The caret symbol (^) and help response indicate an error with the 05 entry. To display the correct syntax, press Ctrl-P or the Up Arrow. You can also reenter the command string, and then enter a space character, a question mark, and press Enter.

WAE# clock set 13:32:00 23 December ?
<1993-2035> Year
WAE# clock set 13:32:00 23 December
 

Enter the year using the correct syntax, and press Return to execute the command.

WAE# clock set 13:32:00 23 December 2005
WARNING: Setting the clock may cause a temporary service interruption.
Do you want to proceed? [no] yes

WAE#
 

Using the no Form of Commands

Almost every configuration command has a no form. The no form of a command is generally used to disable a feature or function, but it can also be used to set the feature or function to its default values. Use the command without the no keyword to reenable a disabled feature or to enable a feature that is disabled by default.

Using System Help

You can obtain help when you enter commands by using the following methods:

  • For a brief description of the context-sensitive help system, enter help.
  • To list all commands for a command mode, enter a question mark (?) at the system prompt.
  • To obtain a list of commands that start with a particular character set, enter an abbreviated command immediately followed by a question mark (?).
WAE# cl?
clear clock
 
  • To list the command keywords or arguments, enter a space and a question mark (?) after the command.
WAE# clock ?
read-calendar Read the calendar and update system clock
set Set the time and date
update-calendar Update the calendar with system clock

Saving Configuration Changes

To avoid losing new configurations, save them to NVRAM using the copy or write commands, as shown in the following example:

WAE# copy running-config startup-config
 

or

WAE# write

This section describes how to navigate the WAAS directories on a WAE and provides directory descriptions useful for troubleshooting and monitoring the WAE.

Navigating WAAS Directories

The WAAS CLI provides several commands for navigating among directories and viewing their contents. These commands are entered from privileged EXEC mode. Table 1-3 lists and describes these commands.

 

Table 1-3 WAAS Navigation Commands

Command
Description

cd [ directory-name ]

Change Directory—Moves you from the current directory to the specified directory in the WAAS tree. If no directory is specified, cd takes you up one directory.

deltree directory-name

Remove Directory Tree—Deletes the specified directory and all subdirectories and files without displaying a warning message to you.

dir [ directory-name ]

Show Directory—Lists the size, date of last changes, and the name of the specified directory (or all directories if one is not specified) within the current directory path. The output from this command is the same as the lls command.

ls [ directory-name ]

Show Directory Names—Lists the names of directories in the current directory path.

lls [ directory-name ]

Show Directory—Lists the size, the date of the last changes, and the name of the specified directory (or all directories if one is not specified) within the current directory path. The output from this command is the same as the dir command.

mkdir directory-name

Create Directory—Creates a directory of the specified name in the current directory path.

pwd

Present Working Directory—Lists the complete path from where this command is entered.

rmdir directory-name

Delete Directory—Removes the specified directory from the current directory path. All files in the directory must first be deleted before the directory can be deleted.

The following example displays a detailed list of all the files for the WAE’s current directory:

WAE# dir

Directory Descriptions

Several top-level directories of the WAAS software contain information used internally by the software and are not useful to you. These directories include the core_dir, crash, downgrade, errorlog, lost+found, sa, service_logs, spool, and var directories.

Table 1-4 describes the directories that contain information that is useful for troubleshooting or monitoring.

 

Table 1-4 WAAS Directory Descriptions

Directory/File Name
Contents

actona

This directory contains the current software image installed on the WAAS device and any previous images that were installed.

logs

This directory contains application-specific logs used in troubleshooting. The actona subdirectory contains the commonly used Manager.log, Utilities.log, and Watchdog.log log files. See the Cisco Wide Area Application Services Configuration Guide for more details about how these log files are used.

syslog.txt

This file is the central repository for log messages. Important messages about the operation of WAAS or its components are sometimes logged in this file. They are often intermingled with routine messages that require no action. You may be requested to provide this file, the output of the show tech-support EXEC command, and perhaps other output to Cisco TAC personnel if a problem arises.

Managing WAAS Files Per Device

The WAAS CLI provides several commands for managing files and viewing their contents per device. These commands are entered from privileged EXEC mode. Table 1-5 describes the WAAS file management commands.

 

Table 1-5 WAAS File Management Commands

Command
Description

copy { source | image }

Copy—Copies the selected source file, image, or configuration information:

type filename

Display File—Displays the content of the specified file on the screen.

type-tail filename [ line | follow | | { begin LINE | exclude LINE | include LINE }]

Display End of File—Displays the last few lines of the specified file. Can also be used to view the last lines of a file continuously as new lines are added to the file, to start at a particular line in the file, or to include or exclude specific lines in the file.

find-pattern pattern

Find in a File—Searches a file for the specified pattern.

The following example shows how to save the currently running configuration to the startup configuration using the copy EXEC command:

WAE# copy running-config startup-config
 

The following example shows how to remove a file named sample from the directory named test using the delfile command:

WAE# cd test
WAE# ls
sample
sample2
WAE# delfile sample
WAE# ls
sample2
 

The following example shows how to view the last lines of the Watchdog.log file:

WAE# cd logs
WAE# cd actona
WAE# ls
Watchdog.log
WAE# type-tail Watchdog.log
[2006-01-30 15:13:44,769][FATAL] - System got fatal error going to restart.
