Cisco Systems 6000 Fault-Tolerant Configuration, Create the server-side Vlan 3 and enter the SLB

Configuration Examples

	Command		Purpose
Step 9
	Router(config)# ip slb vlan 3 server		Create the server-side VLAN 3 and enter the SLB
			VLAN mode.
Step 10
	Router(config-slb-vlan-server)# ip addr		Assign the CSM IP address on VLAN 3.
	192.158.39.10	255.255.255.0
Step 11
	Router(config-slb-vlan-server)# exit		Exit the submode.
Step 12
	Router(config)# ip slb vserver VIP1		Create a virtual server and enter the SLB vserver
			mode.
Step 13
	Router(config-slb-vserver)# virtual		Create a virtual IP address.
	192.158.38.30 tcp www
Step 14
	Router(config-slb-vserver)# serverfarm		Associate the virtual server with the server farm.
	farm1		Note This step assumes that the server farm has
			already been configured. See the “Configuring
			Server Farms” section on page 24.

1.Enter the exit command to leave a mode or submode. Enter the end command to return to the menu’s top level.

2.The no form of this command restores the defaults.

Note Set the server’s default routes to the CSM’s IP address (192.158.39.10).

Fault-Tolerant Configuration

This section describes a fault-tolerant configuration. In this configuration, two separate Catalyst 6000 family chassis each contain a CSM.

Note You can create a fault-tolerant configuration in either the secure (router) mode or nonsecure (bridge) mode.

In the secure (router) mode, the client- and server-side VLANs provide the fault-tolerant (redundant) connection paths between the CSM and the routers on the client side and the servers on the server side. In a redundant configuration, two CSMs perform primary and secondary roles. Each CSM contains the same VLAN, IP, virtual server, server pool, and real server information. From the client-side and server-side networks, each CSM is configured identically. The network sees the fault-tolerant configuration as a single CSM.

Configuring fault-tolerance requires the following:

•Two CSMs that are installed in the Catalyst 6000 family chassis.

•Identically configured CSMs. One CSM is configured as the primary; the other is configured as the secondary.

•Each CSM connected to the same client- and server-side VLANs.

•Communication between the CSMs is provided by a shared private VLAN.

•A network that sees the redundant CSMs as a single entity.

•With Cisco IOS Release 12.1(8)E and later, you must configure Quality of Service (QoS) on each CSM in the fault-tolerant pair.

Figure 11 shows the QoS configuration topology.
