Usage Guidelines

To check the status of member switches in the active and backup areas before or after a smooth upgrade, run the display upgrade state command.

If you specify the slot slot-id parameter in the command, you can check whether the member switch with this slot ID has been upgraded successfully.

If the master switch of a stack restarts or experiences a master/standby switchover after a smooth upgrade, area information will be deleted from the master switch, and the Area field of the master switch will be displayed as unknown.
