Usage Guidelines
The mode sso command can be entered only from within redundancy configuration mode.
Follow these guidelines when configuring your system to SSO mode:
•
You must use identical Cisco IOS images on the switches in the stack to support SSO mode. Redundancy
may not work due to differences between the Cisco IOS releases.
•
If you perform an online insertion and removal (OIR) of the module, the switch resets during the stateful
switchover and the port states are restarted only if the module is in a transient state (any state other than
Ready).
•
The forwarding information base (FIB) tables are cleared on a switchover. Routed traffic is interrupted
until route tables reconverge.
Examples
This example shows how to set the redundancy mode to SSO:
Device(config)# redundancy
Device(config-red)# mode sso
Device(config-red)#
