Chapter 41 Configuring Web Cache Services By Using WCCP
Monitoring and Maintaining WCCP
This example shows how to configure SVIs and how to enable the web cache service with a multicast
group list. VLAN 299 is created and configured with an IP address of 175.20.20.10. Gigabit Ethernet
port 1 is connected through the Internet to the web server and is configured as an access port in VLAN
299. VLAN 300 is created and configured with an IP address of 172.20.10.30. Gigabit Ethernet port 2
is connected to the application engine and is configured as an access port in VLAN 300. VLAN 301 is
created and configured with an IP address of 175.20.30.50. Fast Ethernet ports 3 to 6, which are
connected to the clients, are configured as access ports in VLAN 301. The switch redirects packets
received from the client interfaces to the application engine.

Monitoring and Maintaining WCCP
To monitor and maintain WCCP, use one or more of the privileged EXEC commands in Table 41-2:
Table 41-2 Commands for Monitoring and Maintaining WCCP
Command Purpose
clear ip wccp web-cache Removes statistics for the web-cache service.
show ip wccp web-cache Displays global information related to WCCP.
show ip wccp web-cache detail Displays information for the switch and all application engines in the
WCCP cluster.
