Configuring a WCCPv2 Service Group
You can configure a WCCPv2 service group. You can optionally configure the following:
• Open or closed mode (with a service list)—Controls the traffic type that this service group handles.
• WCCPv2 authentication—Authenticates the WCCPv2 messages using an MD5 digest. WCCPv2
discards messages that fail authentication.
Note You must configure the same authentication on all members of the WCCPv2 service group.
• Redirection limits—Controls the traffic that is redirected to the cache engine.
Closed mode for dynamic service groups requires a service list ACL that specifies the protocol and port
information that will be used for the service group. If there are no members in the service group, packets
matching the service-list ACL will be dropped.
Note The service-list keyword ACL must have only protocol and port information. To restrict traffic that is
considered for redirection, use the redirect-list keyword.
Note You must enter the ip wccp command with all your required parameters. Any subsequent entry of the ip
wccp command overwrites the earlier configuration.
BEFORE YOU BEGIN
Ensure that you are in the correct VDC (or use the switchto vdc command).
