Configuring Supervisor Engine Redundancy
Command
Step 3
Switch# show running-config
Step 4
Switch# show redundancy
[clients | counters | history | states]
This example shows how to configure the system for SSO and display the redundancy facility
information:
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

Available system uptime = 10 minutes Switchovers system experienced = 0
Standby failures = 1
Last switchover reason = none
Hardware Mode = Duplex
Configured Redundancy Mode = Stateful Switchover
Operating Redundancy Mode = Stateful Switchover
Maintenance Mode = Disabled
Communications = Up
Active Location = slot 3
Current Software state = ACTIVE
Uptime in current state = 9 minutes
Image Version = Cisco IOS Software, Catalyst 4500 L3 Switch Software

Purpose
Verifies that SSO or RPR is configured.
Displays the redundancy information (counter, state, and
so on) for the active and standby supervisor engines.
