Note This command is supported only on Catalyst 2960-S switches running the LAN base image.


The summary information about the switch stack shows these states:

Waiting—A switch is booting up and waiting for communication from other switches in the stack. The switch has not yet determined whether or not it is a stack master.

Stack members not participating in a stack master election remain in the waiting state until the stack master is elected and ready.

Initializing—A switch has determined whether its stack master status. If it is not the stack master, it is receiving its system- and interface-level configuration from the stack master and loading it.

Ready—The member has completed loading the system- and interface-level configurations and can forward traffic.

Master Re-Init—The state immediately after a master re-election and a different member is elected master. The new master is re-initializing its configuration. This state applies only to the new master.

Ver Mismatch—A switch in version mismatch mode. Version-mismatch mode is when a switch joining the stack has a different stack protocol minor version number than the master.

A typical state transition for a stack member (including a stack master) booting up is Waiting -> Initializing -> Ready.

A typical state transition for a stack member to a stack master after an master election is Ready -> Master Re-Init -> Ready.

A typical state transition for a stack member in version mismatch mode is Waiting -> Ver Mismatch.
