Catalyst 6000 family Supervisor IOS Release 12.1(8)EX for Supervisor Engine 1 with MSFC1
(c6sup11−jsv−mz.121−8.EX)
• 
Catalyst 6000 family CSM Software Release 2.1(0) (c6slb−apc.2−1−1.bin)
• 
The CSM runs on Cisco IOS Release 12.1(6)E or later. If you are using a Supervisor Engine 2, you must use
Cisco IOS Release 12.1(8a)E or later.
Operation Mode
Client and server connections through the CSM can use either Layer 2 or Layer 3 switching. 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. In this case, the servers' default gateway and the routing through the network from servers to
the CSM server side VLAN must direct all load balanced traffic from the servers through the CSM, or
serverfarm client NAT must be configured in the CSM for all traffic destined to servers in the server farm. A
client sends a request to a VIP address,  and the CSM forwards the request to a server that can satisfy the
request. The server forwards the response to the CSM, and the CSM forwards the response to the client.
When the client side and server side VLANs are in different subnets, you can configure the CSM in secure
(router) mode. This sample configuration focuses on secure (router) mode configuration. When the client side
and server side VLANs are in the same subnet, you can configure the CSM to operate in single subnet
(bridge) mode. Refer to the sample configurations below for more information.
Network Diagram
The client side and server side VLANs are on different subnets in secure (router) mode. The diagram shows
how the secure (router) mode configuration is set up.
