Dual-Supervisor Configuration
When deploying a system made of two supervisors, one supervisor is normally active and the other is at standby, at
least from a management plane point of view.
least from a management plane point of view.
Cisco NX-OS Software offers the following commands to check the supervisor redundancy status:
NXOS : #show system redundancy status
In Cisco NX-OS, you can trigger a supervisor switch-over by issuing the command:
NXOS : #system switchover
In Cisco Catalyst IOS Software, when two supervisors are present in the same chassis (which is currently not
applicable to virtual switching system (VSS)-mode deployments), redundant supervisor configurations are handled
through the following commands:
applicable to virtual switching system (VSS)-mode deployments), redundant supervisor configurations are handled
through the following commands:
Catalyst IOS : (config)# redundancy
Catalyst IOS : (config)# mode sso
Catalyst IOS : (config)# auto-sync running-config
Cisco Catalyst IOS Software offers the following commands to check the supervisor redundancy status:
Catalyst IOS : (config)# show redundancy state
In Cisco Catalyst IOS Software, you can trigger a supervisor switchover using the following command:
Catalyst IOS : (config)# redundancy force-switchover
Upgrade Procedures
This document is not an operational guide, so it doesn’t cover in detail software upgrades and troubleshooting. On
the other hand, for a proper design it is important to have a basic idea of which devices support In-Service Software
Upgrade (ISSU) and how it works. It is also important to understand upgrades in a virtualized server environment.

ISSU
The ISSU concept is applicable to the Cisco Nexus 7000 Series platform. In a Cisco NX-OS system, you can perform
in-service software upgrades as described in the documentation at this link:

In a Cisco Catalyst IOS system, you can upgrade the system in an ISSU fashion using the Enhanced Fast Supervisor
Upgrade (eFSU) as follows:
