Configuring Supervisor Engine Redundancy
Configuring Redundancy
To configure redundancy, perform this task:
When configuring redundancy, note the following:
•
The sso keyword is supported in Cisco IOS Release 12.2(20)EWA and later releases.
• The rpr keyword is supported in Cisco IOS Release 12.1(12c)EW and later releases.
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

Command Purpose
Step 1
Switch(config)# redundancy
Enters redundancy configuration mode.
Step 2
Switch(config-red)# mode {sso | rpr} Configures SSO or RPR. When this command is entered,
the redundant supervisor engine is reloaded and begins to
work in SSO or RPR mode.
Step 3
Switch# show running-config
Verifies that SSO or RPR is enabled.
Step 4
Switch# show redundancy
[clients | counters | history | states]
Displays the redundancy information (counter, state, and
so on) for the active and redundant supervisor engines.
