Chapter 43 Configuring Web Cache Services By Using WCCP
Configuring WCCP
To disable the web cache service, use the no ip wccp web-cache global configuration command. To
disable inbound packet redirection, use the no ip wccp web-cache redirect in interface configuration
command. After completing this procedure, you should configure the application engines in the network.

command. After completing this procedure, you should configure the application engines in the network.
This example shows how to configure routed interfaces and to enable the web cache service with a
multicast group address and a redirect access list. Gigabit Ethernet port 1 is connected to the application
engine, is configured as a routed port with an IP address of 172.20.10.30, and is re-enabled. Gigabit
Ethernet port 2 is connected through the Internet to the web server, is configured as a routed port with
an IP address of 175.20.20.10, and is re-enabled. Gigabit Ethernet ports 3 to 6 are connected to the
clients and are configured as routed ports with IP addresses 175.20.30.20, 175.20.40.30, 175.20.50.40,
and 175.20.60.50. The switch listens for multicast traffic and redirects packets received from the client
interfaces to the application engine.
