Chapter 43 Configuring Web Cache Services By Using WCCP
Configuring WCCP
When packets are redirected, the output ACLs associated with the redirected interface are applied to the
packets. Any ACLs associated with the original port are not applied unless you specifically configure
the required output ACLs on the redirected interfaces.
WCCP and Switch Stacks
WCCP support is the same for a switch stack as for a standalone switch. WCCP configuration
information is propagated to all switches in the stack. All switches in the stack, including the stack
master, process the information and program their hardware. For more information about switch stacks,
see
Chapter 6, “Managing Switch Stacks.”
The stack master performs these WCCP functions:
• It receives protocol packets from any WCCP-enabled interface and sends them out any
WCCP-enabled interface in the stack.
• It processes the WCCP configuration and propagates the information to all stack members.
• It distributes the WCCP information to any switch that joins the stack.
• It programs its hardware with the WCCP information it processes.
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:
