This document provides a sample configuration for transparent caching on the Cache Engine-Network Module (CE-NM). The IP address that is specified in the router-list should be the default gateway for the CE-NM.
There are no specific requirements for this document.
This document is not restricted to specific software and hardware versions.
The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.
Refer to the Cisco Technical Tips Conventions for more information on document conventions.
In this section, you are presented with the information to configure the features described in this document.
This document uses these configurations:
Cache Engine: Web Cache Communication Protocol Version 2 (WCCP 2) and specifying Layer 2 (L2) redirection on the NM
2600 Router: WCCP 2 redirection on the 2600 router
ce-4#config Enter configuration commands, one per line. End with CNTL/Z ce-4(config)#wccp router-list 1 10.1.1.1 !--- This is the IP address of the Cisco 2600 router interface. ce-4(config)#wccp web-cache router-list-num 1 l2-redirect ce-4(config)#wccp version 2 ce-4(config)#^Z
cat#configure terminal Enter configuration commands, one per line. End with CNTL/Z. cat(config)#ip wccp web-cache cat(config)#interface fastEthernet 2/2 !--- Internet facing interface. cat(config-if)#ip wccp web-cache redirect out !--- Internet facing interface. cat(config-if)#^Z
This section provides information you can use to confirm your configuration is working properly.
show ip wccp web-cache detail—Displays statistics for only the first packet of a Layer 2 redirected flow, which provides an indication of how many flows, rather than packets, use Layer 2 redirection.
