Chapter 41 Configuring Web Cache Services By Using WCCP

Configuring WCCP

	Command	Purpose
Step 16
	show ip wccp web-cache	Verify your entries.
	and
	show running-config
Step 17
	copy running-config startup-config	(Optional) Save your entries in the configuration file.

To disable the web cache service, use the no ip wccp web-cacheglobal 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.
