Configuring WCCP

These WCCP features are not supported in this software release:

•Packet redirection on an outbound interface that is configured by using the ip wccp redirect out

interface configuration command. This command is not supported.

•The GRE forwarding method for packet redirection is not su pported.

•The hash assignment method for load balancing is not supported.

•There is no SNMP support for WCCP.

Configuring WCCP

These sections describe how to configure WCCP on your switch:

•Default WCCP Configuration, page 41-5

•WCCP Configuration Guidelines, page 41-5

•Enabling the Web Cache Service, page 41-6 (required)

Table41-1 shows the default WCCP configuration.

Before configuring WCCP on your switch, make sure to follow these configuration guidelines:

•The application engines and switches in the same service group must be in the same subnetwork

directly connected to the switch that has WCCP enabled.

•Configure the switch interfaces that are connected to the web clients, the application engines, and

the web server as Layer 3 interfaces (routed ports and switch virtual interfaces [SVIs]). For WCCP

packet redirection to work, the servers, application engines, and clients must be on different subnets.

•Use only nonreserved multicast addresses when configuring a single multicast address for each

application engine.

•WCCP entries and PBR entries use the same TCAM region. WCCP is suppor ted only on the

templates that support PBR: access, routing, and dual IPv4/v6 routing.

•When TCAM entries are not available to add WCCP entries, packets are no t redirected and are

forwarded by using the standard routing tables.
