Switchover Processes

Switchovers occur by one of the following two processes:

• The active supervisor module fails and the standby supervisor module automatically takes over.
• You manually initiate a switchover from an active supervisor module to a standby supervisor module.

Once a switchover process has started another switchover process cannot be started on the same switch until a stable standby supervisor module is available.

Caution

If the standby supervisor module is not in a stable state (ha-standby), a switchover is not performed.

This section includes the following topics:

• Synchronizing Supervisor Modules
• Manual Switchover Guidelines
• Manually Initiating a Switchover
