How to Configure WCCP
The following configuration tasks assume that you have already installed and configured the content engines
you want to include in your network. You must configure the content engines in the cluster before configuring
WCCP functionality on your routers or switches. Refer to the
engine configuration and setup tasks.

Configuring WCCP

Perform this task to configure WCCP.
Until you configure a WCCP service using the ip wccp{web-cache | service-number} global configuration
command, WCCP is disabled on the router. The first use of a form of the ip wccp command enables WCCP.
By default WCCPv2 is used for services, but you can use WCCPv1 functionality instead.
Use the ip wccp web-cache password command to set a password for a router and the content engines in a
service group. MD5 password security requires that each router and content engine that wants to join a service
group be configured with the service group password. The password must be up to eight characters in length.
Each content engine or router in the service group will authenticate the security component in a received
WCCP packet immediately after validating the WCCP message header. Packets failing authentication will be
discarded.
