Chapter 11 Configuring Supervisor Engine Redundancy Using RPR and SSO on Supervisor Engine 7-E, Supervisor
Configuring Supervisor Engine Redundancy
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
Redundant System Information :
------------------------------
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
Current Processor Information :
------------------------------
Active Location = slot 3
Current Software state = ACTIVE
Uptime in current state = 9 minutes
Image Version = Cisco IOS Software, Catalyst 4500 L3 Switch Software

This example shows how to display redundancy facility state information:
Switch# show redundancy states
my state = 13 -ACTIVE
peer state = 8 -STANDBY HOT
Mode = Duplex
Unit = Primary
Unit ID = 3
Redundancy Mode (Operational) = Stateful Switchover
Step 3
Switch# show running-config
Verifies that SSO or RPR is configured.
Step 4
Switch# show redundancy
[clients | counters | history | states]
Displays the redundancy information (counter, state, and
so on) for the active and standby supervisor engines.
