WCCP Router config

I found this paragraph in the IOS 12.x documentation. The second sentence seems odd to me. Because WCCP redirection was enabled on a specific interface, it affects all interfaces on a router. Does it only affect interfaces that have an outbound redirection statement associated with them or does it affect all traffic on all interfaces?

Configuring WCCP for redirection for inbound traffic on interfaces allows you to avoid the overhead associated with CEF forwarding for outbound traffic. Setting an output feature on any interface results in the slower switching path of the feature being taken by all packets arriving at all interfaces. Setting an input feature on an interface results in only those packets arriving at that interface taking the configured feature path; packets arriving at other interfaces will use the faster default path. Configuring WCCP for inbound traffic also allows packets to be classified before the routing table lookup, which translates into faster redirection of packets.

Re: WCCP Router config

Often times complex troubleshooting issues are best addressed in an interactive session with one of our trained technical assistance engineers. While other forum users may be able to help, it’s often difficult to do so for this type of issue.

If anyone else in the forum has some advice, please reply to this thread.

Thank you for posting.


Re: WCCP Router config

Has anyone tried configuring a Cisco 2621 with NAT/CBAC/CEF/WCCP simultaneously? I have a branch office connection with a single router and am having serious trouble getting CBAC and WCCP to work nicely together. I'm redirecting to a Volera Cache Engine. Synopsis of config:

ip wccp web-cache redirect-list http

ip wccp 98 redirect-list streams

ip cef

ip inspect audit-trail

ip inspect name filter cuseeme

ip inspect name filter ftp

ip inspect name filter h323

ip inspect name filter http java-list 90

ip inspect name filter netshow

ip inspect name filter realaudio

ip inspect name filter rtsp

ip inspect name filter streamworks

ip inspect name filter tcp

ip inspect name filter udp

ip inspect name filter vdolive

ip audit notify log

ip nat inside

ip wccp web-cache redirect in
