Configure the Web Cache Control Protocol

FC-118

Configuration Fundamentals Configuration Guide

Enable the Web Cache Control Protocol on the Router

To enable an interface to redirect Web trafﬁc to the Cisco Cache Engine using the Web Cache

Control Protocol, use the following commands beginning in global conﬁguration mode:

Monitor the Web Cache Control Protocol

To monitor the Web Cache Control Protocol, use any of the following commands in EXEC mode:

The show ip wccp and show ip wccp web-caches commands display a count of the number of

packets redirected. Use the clear ip wccp EXEC command to clear this counter.

What to Do Next

To use WCCP, the Cisco Cache Engine must be properly conﬁgured. Refer to the Using the Cisco

Cache Engine publication for details on conﬁguring the Cisco Cache Engine. Keep these important

points in mind:

• The IP address of the router must be conﬁgured as the home router for the Cisco Cache Engine.

• Versions of software on the Cisco Cache Engines must be compatible with the router.

• The Cisco Cache Engines must not have their packets encrypted or compressed and should be

part of the “inside” Network Address Translation if one is present.

• Placing a Cisco Cache Engine beyond a Web-cache-redirect enabled interface and along the route

to the server will not cause the IP route cache to be populated with an entry.

Step Command Purpose

1 ip wccp enable Enable the router to use the Web Cache Control Protocol.

2 ip wccp redirect-list {number | name} (Optional) Specify the redirect access list. Only packets that

match this access list are redirected. If you do not conﬁgure

this command, all Web-based packets are redirected.

3 interface interface Enter interface conﬁguration mode.

4 ip web-cache redirect Conﬁgure the interface connected to the Internet to redirect

Web trafﬁc to the Cisco Cache Engine.

5 ip route-cache same-interface (Optional) If the client and a Cisco Cache Engine are

located on the same network, conﬁgure the router to use the

fast switching path on the interface.

6 end Exit conﬁguration mode.

7 copy running-conﬁg startup-conﬁg Save the conﬁguration.

Step Command Purpose

1 show ip wccp Display global Web Cache Control Protocol statistics.

2 show ip wccp web-caches Display information about all known Cisco Cache Engines.

3 show ip interface Show whether Web cache redirecting is enabled on an

interface.
