Chapter 10 Configuring DHCP, DDNS, and WCCP Services
Configuring Web Cache Services Using WCCP
The standard service is web-cache , which intercepts TCP port 80 (HTTP) traffic and redirects that traffic
to the cache engines, but you can identify a service number if desired between 0 and 254. For example,
to transparently redirect native FTP traffic to a cache engine, use WCCP service 60. You can enter this
command multiple times for each service group you want to enable.
The redirect-list access_list argument controls traffic redirected to this service group.
The group-list access_list argument determines which web cache IP addresses are allowed to participate
in the service group.
The password password argument specifies MD5 authentication for messages received from the service
group. Messages that are not accepted by the authentication are discarded.
Step 2
To enable WCCP redirection on an interface, enter the following command:
hostname(config)# wccp interface interface_name { web-cache | service_number} redirect in

For example, to enable the standard web-cache service and redirect HTTP traffic that enters the inside
interface to a web cache, enter the following commands:
hostname(config)# wccp web-cache
hostname(config)# wccp interface inside web-cache redirect in
