Configuring Supervisor Engine Redundancy

Configuring Redundancy

To configure redundancy, perform this task:
Command
Step 1
Switch(config)# redundancy
Step 2
Switch(config-red)# mode {sso | rpr}
Step 3
Switch# show running-config
Step 4
Switch# show redundancy
[clients | counters | history | states]
When configuring redundancy, note the following:
•
•
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

Purpose
Enters redundancy configuration mode.
Configures SSO or RPR. When this command is entered,
the redundant supervisor engine is reloaded and begins to
work in SSO or RPR mode.
Verifies that SSO or RPR is enabled.
Displays the redundancy information (counter, state, and
so on) for the active and redundant supervisor engines.
