Configuring a General WCCPv2 Session: Example
configure terminal
ip wccp web-cache group-address 224.1.1.100 password password1
interface ethernet0 ip wccp web-cache redirect out
exit
ip wccp check services all ! Configures a check of all WCCP services.

ip wccp
To enable support of the specified Web Cache Communication Protocol (WCCP) service for participation in a service group, use the ip wccp command in global configuration mode.

ip wccp check acl outbound
To check the outbound access control list (ACL) for Web Cache Communication Protocol (WCCP), use the ip wccp check acl outbound command in global configuration mode.

ip wccp check services all
To enable all Web Cache Communication Protocol (WCCP) services, use the ip wccp check services all command in global configuration mode.

ip wccp group-listen
To configure an interface on a router to enable or disable the reception of IP multicast packets for Web Cache Communication Protocol (WCCP), use the ip wccp group-listen command in interface configuration mode.

Router# configure terminal
Router(config)# ip multicast-routing
Router(config)# ip wccp web-cache group-address 224.1.1.100
Router(config)# interface ethernet 0
Router(config-if)# ip wccp web-cache group-listen

ip wccp redirect
To enable packet redirection on an outbound or inbound interface using Web Cache Communication Protocol (WCCP), use the ip wccp redirect command in interface configuration mode.

The following example shows how to configure a session in which HTTP traffic arriving on Ethernet interface 0/1 is redirected to a Cisco Cache Engine:
Router(config)# ip wccp web-cache
Router(config)# interface ethernet 0/1
Router(config-if)# ip wccp web-cache redirect in

ip wccp redirect exclude in
To configure an interface to exclude packets received on an interface from being checked for redirection, use the ip wccp redirect exclude in command in interface configuration mode.

ip wccp version
To specify the version of Web Cache Communication Protocol (WCCP), use the ip wccp version command in global configuration mode.
ip wccp version {1 2}

ip wccp web-cache accelerated
To enable the hardware acceleration for WCCP version 1, use the ip wccp web-cache accelerated command in global configuration mode.
