Configuring Cache Services By Using WCCP
This chapter describes how to configure your Catalyst 3750-X or 3560-X switch to redirect traffic to
wide-area application engines (such as the Cisco Cache Engine 550) by using the Web Cache
Communication Protocol (WCCP). This software release supports only WCCP version 2 (WCCPv2).
Note To use this feature, the switch or the stack master must be running the IP services feature set.
WCCP is a Cisco-developed content-routing technology that you can use to integrate wide-area
application engines—referred to as application engines—into your network infrastructure. The
application engines transparently store frequently accessed content and then fulfill successive requests
for the same content, eliminating repetitive transmissions of identical content from servers. Application
engines accelerate content delivery and ensure maximum scalability and availability of content. In a
service-provider network, you can deploy the WCCP and application engine solution at the points of
presence (POPs). In an enterprise network, you can deploy the WCCP and application engine solution
at the regional site and the small branch office.
Unless otherwise noted, the term switch refers to a Catalyst 3750-X or 3560-X standalone switch and to
a Catalyst 3750-X switch stack.
Note For complete syntax and usage information for the commands used in this chapter, see the “WCCP
Router Configuration Commands” section in the “System Management Commands” part of the Cisco
IOS Configuration Fundamentals Command Reference, Release 12.4.
