This INTEGER object reports the redundancy state of an in-chassis standby supervisor module in a virtual switch environment, distinguishing notApplicable, rprWarm (running as a Distributed Forwarding Card in RPR warm state), and cSSO (hot standby). This state tells an admin how quickly the standby supervisor could take over if the active one failed, since rprWarm implies a slower, less synchronized failover than cSSO. An engineer planning a maintenance window on the active supervisor would check this object first to confirm the standby is in cSSO rather than the weaker rprWarm state before triggering a switchover.
