Cisco Cisco Content Switching Module Technical Manual

This configuration can be used with any software and hardware versions that support the CSM.

Clients and servers communicate through the CSM using either Layer 2 or Layer 3  technology in a specific
VLAN configuration. Clients connect to the client side VLAN and servers connect to the server side VLAN.
Servers and clients can exist on different subnets. Servers can also be located more than one hop away and
connect to the server−side VLAN through routers. A client sends a request to one of the module's VIP
addresses. The CSM forwards this request to a server that can respond to the request. The server then forwards
the response to the CSM, and the CSM forwards the response to the client.

When the client−side and server−side VLANs are on the same subnets, you can configure the CSM in single
subnet (bridge) mode. This document describes single subnet (bridge) mode.

When the client−side and server−side VLANs are on different subnets, you can configure the CSM to operate
in a secure (router) mode. For more information, refer to Configuring Secure (Router) Mode on the CSM.

The following diagram illustrates different VLANs and different subnets.

Complete these steps:

Create the client and server VLAN on the MSFC.

cat#conf t

cat(config)#vlan 100

cat(config−vlan)#exit
