Configuring SSO

You must configure SSO in order to use NSF with any supported protocol.
To configure SSO, perform this task:
Command
Step 1
Switch(config)# redundancy
Step 2
Switch(config-red)# mode sso
Step 3
Switch(config-red)# end
Step 4
Switch# show running-config
Step 5
Switch# show redundancy states
The sso keyword is supported in Cisco IOS Release 12.2(20)EWA and later releases.
Note
This example shows how to configure the system for SSO and display the redundancy state:
Switch> enable
Switch# configure terminal
Enter configuration commands, one per line.
Switch(config)# redundancy
Switch(config-red)# mode sso
Switch(config-red)# end
Switch# show redundancy states
my state = 13 -ACTIVE
Redundancy Mode (Operational) = sso
Redundancy Mode (Configured)
Manual Swact = Enabled
Communications = Up
client count = 29
client_notification_TMR = 30000 milliseconds
