Chapter 1 Configuring Traffic Interception
Configuring WCCP on WAEs
Note For information about how to use the CLI to specify the service group password on a router,
see the “Setting a Service Group Password on a Router” section on page 1-10.
Step 11 Click Submit to save the settings.
To configure WCCP settings from the CLI, you must first set the interception method to WCCP by using
the interception-method global configuration command, and then you can use the wccp router-list and
wccp tcp-promiscuous global configuration commands.
Configuring and Viewing WCCP Router Lists for WAEs
You can configure and view one router list from the Central Manager through the WCCP settings (see
the “Configuring or Viewing the WCCP Settings on WAEs” section on page 1-17). The Central Manager
supports only a single router list assigned to the WCCP service and removes any other existing router
lists that may be configured through the CLI if you use the Central Manager to configure a router list,
check or uncheck the Use Default Gateway check box in the WCCP settings page, or submit the WCCP
settings page. If you want to configure a router list through the CLI, you can use the wccp router-list
global configuration command.
Note WCCP must be enabled before you can use the WCCP global configuration commands.
To delete a router list, use the no wccp router-list global configuration command.
To view an unassigned router list configured by the wccp router-list command, use the show
running-config wccp EXEC command.
Configuring WAEs for a Graceful Shutdown of WCCP
To prevent broken TCP connections, the WAE performs a clean shutdown of WCCP after you disable
WCCP Version 2 on a WAE or reload the WAE from the CLI. You can perform this task locally through
the CLI on a device by entering the no enable WCCP configuration command.
The WAAS Central Manager also allows you to disable WCCP Version 2 on a WAE, but this does not
perform a graceful shut down of WCCP connections. To disable WCCP immediately for a chosen device,
uncheck the Enable WCCP check box in the WAAS Central Manager Interception Configuration
window. (See Figure 1-3.)
Note If you use the Central Manager to disable WCCP on a WAAS device, the Central Manager immediately
shuts down WCCP and closes any existing connections, ignoring the setting configured by the
wccp shutdown max-wait global configuration command. If you want to gracefully shut down WCCP
connections, use the no enable WCCP configuration command on the WAAS device.
During a graceful shut down, the WAE does not reboot until one of the following occurs:
• All the connections have been serviced.
