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.
