Specifies the web-cache service.
Note
Dynamic service identifier, which means the service definition is dictated
by the cache. The dynamic service number can be from 0 to 254. The
maximum number of services is 8, which includes the web-cache service
specified with the web-cache keyword.
Note
(Optional) This option applies only to hardware-accelerated routers. This
keyword configures the service group to prevent a connection being
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.
(Optional) Multicast IP address that communicates with the WCCP
service group. The multicast address is used by the router to determine
which cache engine should receive redirected messages.
(Optional) Access list that controls traffic redirected to this service group.
The access-list argument should consist of a string of no more than 64
characters (name or number) that specifies the access list.
(Optional) Access list that determines which cache engines are allowed to
participate in the service group. The access-list argument specifies either
the number or the name of a standard or extended access list.
(Optional) Message digest algorithm 5 (MD5) authentication for messages
received from the service group. Messages that are not accepted by the
authentication are discarded. The encryption type can be 0 or 7, with 0
specifying not yet encrypted and 7 for proprietary. The password argument
can be up to eight characters in length.
Chapter 2 Cisco IOS Commands for the Catalyst 4500 Series Switches
Web cache counts as one service. The maximum number of
services, including those assigned with the service-number
argument, are 8.
If Cisco cache engines are being used in your service group, the
reverse-proxy service is indicated by a value of 99.
