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.
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.

Step 12
ip wccp
{
web-cache
|
service-number
}
redirect in
Redirect packets received from the client to the application engine.
Enable this on the interface connected to the client.
Step 13
ip wccp
{
web-cache
|
service-number
}
group-listen
(Optional) When using a multicast group address,
group-listen
enables
the interface to listen for the multicast address. Enable this on the
interface connected to the application engine.
Step 14
exit
Return to global configuration mode. Repeat Steps 8 through 13 for each
client.
Step 15
end
Return to privileged EXEC mode.
Step 16
show ip wccp web-cache
and
show running-config
Verify your entries.
Step 17
copy running-config startup-config
(Optional) Save your entries in the configuration file.
