Chapter 1 Configuring Cache Services By Using WCCP
Configuring WCCP
Stack members receive the WCCP information from the master switch and program their hardware.
Unsupported WCCP Features
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 supported.
• 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 1-5
• WCCP Configuration Guidelines, page 1-5
• Enabling the Cache Service, page 1-6 (required)
Default WCCP Configuration
WCCP Configuration Guidelines
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 clients, the application engines, and the
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 supported 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 not redirected and are
forwarded by using the standard routing tables.
