Configuring SSO
You must configure SSO in order to use NSF with any supported protocol.
To configure SSO, perform this task:
Note The sso keyword is supported in Cisco IOS Release 12.2(20)EWA and later releases.
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. End with CNTL/Z.
Switch(config)# redundancy
Switch(config-red)# mode sso
Switch(config-red)# end
Switch# show redundancy states
my state = 13 -ACTIVE
peer state = 8 -STANDBY HOT
Mode = Duplex
Unit = Primary
Unit ID = 5
Redundancy Mode (Operational) = sso
Redundancy Mode (Configured) = sso
Split Mode = Disabled
Manual Swact = Enabled
Communications = Up
client count = 29
client_notification_TMR = 30000 milliseconds
keep_alive TMR = 9000 milliseconds
keep_alive count = 1
Command Purpose
Step 1
Switch(config)# redundancy
Enters redundancy configuration mode.
Step 2
Switch(config-red)# mode sso
Configures SSO. When this command is entered, the
redundant supervisor engine is reloaded and begins to
work in SSO mode.
Step 3
Switch(config-red)# end
Returns to EXEC mode.
Step 4
Switch# show running-config
Verifies that SSO is enabled.
Step 5
Switch# show redundancy states
Displays the operating redundancy mode.
