Configuring Connection Redundancy
Router(config-module-csm)# ft group 88 vlan 71
Router(config-slb-ft)# priority 20
Router(config-slb-ft)# preempt
Router(config-slb-ft)# exit
Router(config-module-csm)# interface Vlan136
ip address 10.6.0.3 255.255.0.0
standby 1 priority 100 preempt
standby 1 ip 10.6.0.1
standby 1 track Fa3/6 10
Note
Step 3
Configure EtherChannel on both switches as follows:
Router(console)# interface Port-channel100
Router(console)# switchport
Router(console)# switchport trunk encapsulation dot1q
Router(console)# switchport trunk allowed vlan 136
Note
Step 4
To prevent problems, remove the server and fault-tolerant CSM VLANs as follows:
Router(console)# switchport trunk remove vlan 71
Router(console)# switchport trunk remove vlan 272
Add ports to the EtherChannel as follows:
Step 5
Router(console)# interface FastEthernet3/25
Router(console)# switchport
Router(console)# channel-group 100 mode on
Configuring Connection Redundancy
Connection redundancy prevents open connections from ceasing to respond when the active CSM fails
and the standby CSM becomes active. With connection redundancy, the active CSM replicates
forwarding information to the standby CSM for each connection that is to remain open when the active
CSM fails over to the standby CSM.
To configure connection redundancy, perform this task:
Command
Step 1
Router# configure terminal
Step 2
Router(config)# no ip igmp
snooping
Step 3
Router(config-module-csm)#
vserver virtserver-name
Catalyst 6500 Series Content Switching Module Configuration Note
7-8
To allow tracking to work, preempt must be on.
By default, all VLANs are allowed on the port channel.
Purpose
Enters router configuration mode.
Removes IGMP snooping from the configuration.
Identifies a virtual server and enters the virtual server submode.
