Supervisor Engine Redundancy

The Catalyst 4507R-E and Catalyst 4510R-E switches support supervisor engine redundancy. Redundancy allows a second supervisor engine to take over if the active supervisor engine fails.

With supervisor engine redundancy enabled, if the active supervisor engine fails or if a manual switchover is performed, the redundant supervisor engine becomes the active supervisor engine. The redundant supervisor engine is automatically initialized with the startup configuration of the active supervisor engine. Depending on the configuration this shortens the switchover time from 30 seconds or longer in Route Processor Redundancy (RPR) mode, to less than a second in Stateful Switch Over (SSO) mode.

In addition to the reduced switchover time, supervisor engine redundancy supports these:

Online insertion and removal (OIR) of the redundant supervisor engine

Supervisor engine redundancy allows OIR of the redundant supervisor engine for maintenance. When the redundant supervisor engine is inserted, the active supervisor engine detects it. The redundant supervisor engine boots into a partially initialized state in RPR mode and a fully initialized state in SSO mode.

Software upgrade

Load the new image on the redundant supervisor engine and conduct a switchover. This minimizes downtime during software changes on the supervisor engine.

When power is first applied to a switch, the supervisor engine that boots first becomes the active supervisor engine and remains active until a switchover occurs.

Redundancy requires that both supervisor engines in the chassis are of the same supervisor engine model, and that they use the same Cisco IOS software image.

For more detail about redundancy, refer to the Configuring Supervisor Engine Redundancy Using RPR and SSO chapter of the software configuration guide for your software release.
