Syntax Description
Command Default WCCP services are not enabled on the router.
Command Modes Global configuration (config)

Note Web cache counts as one service. The maximum number of
services, including those assigned with the service-number

specified with the web-cache keyword.
Note If Cisco cache engines are being used in your service group, the
reverse-proxy service is indicat ed by a value of 99.
accelerated (Optional) This option applies only to hardware-accelerated routers. This
keyword configures the service group to prevent a connection be ing
formed with a cache engine unless the cache engine is configured in a way
that allows redirection on the router to benefit from hardware acceleration.
group-address

(Optional) Multicast IP address that communicates with the WCCP
service group. The multicast address is used by the router to determine
which cache engine sh ould receive redirected me ssages.
