Chapter 41 Configuring Web Cache Services By Using WCCP

Configuring WCCP

	Command	Purpose
Step 1
	configure terminal	Enter global configuration mode.
Step 2
	ip wccp {web-cache service-number}	Enable the web cache service, and specify the service number which
	[group-address groupaddress]	corresponds to a dynamic service that is defined by the application
	[group-list access-list][redirect-list	engine. By default, this feature is disabled.
	access-list] [password	(Optional) For group-addressgroupaddress, specify the multicast group
	encryption-number password]
		address used by the switches and the application engines to participate in
		the service group.
		(Optional) For group-listaccess-list, if a multicast group address is not
		used, specify a list of valid IP addresses that correspond to the application
		engines that are participating in the service group.
		(Optional) For redirect-listaccess-list, specify the redirect service for
		specific hosts or specific packets from hosts.
		(Optional) For password encryption-number password, specify an
		encryption number. The range is 0 to 7. Use 0 for not encrypted, and use
		7 for proprietary. Specify a password name up to seven characters in
		length. The switch combines the password with the MD5 authentication
		value to create security for the connection between the switch and the
		application engine. By default, no password is configured, and no
		authentication is performed.
		You must configure the same password on each application engine.
		When authentication is enabled, the switch discards messages that are not
		authenticated.
Step 3
	interface interface-id	Specify the interface connected to the application engine or the web
		server, and enter interface configuration mode.
Step 4
	no switchport	Enter Layer 3 mode.
Step 5
	ip address ip-address subnet-mask	Configure the IP address and subnet mask.
Step 6
	no shutdown	Enable the interface.
Step 7
	exit	Return to global configuration mode. Repeat Steps 3 through 7 for each
		application engine and web server.
Step 8
	interface interface-id	Specify the interface connected to the client, and enter interface
		configuration mode.
Step 9
	no switchport	Enter Layer 3 mode.
Step 10
	ip address ip-address subnet-mask	Configure the IP address and subnet mask.
Step 11
	no shutdown	Enable the interface.
Step 12
	ip wccp {web-cache service-number}	Redirect packets received from the client to the application engine.
	redirect in	Enable this on the interface connected to the client.
Step 13
	ip wccp {web-cache service-number}	(Optional) When using a multicast group address, group-listenenables
	group-listen	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.
