These are the states displayed in the summary information about the switch stack:
• Waiting—The stage when a switch is booting up and waiting for communication from other switches
in the stack. The switch has not yet determined whether it is a stack master or not.
Stack members not participating in a stack master election remain in the waiting state until the stack
master is elected and ready.
• Initializing—The stage when a switch has determined whether it is the stack master or not. If the
switch is not the stack master, it is receiving its system- and interface-level configuration from the
stack master and loading it.
• Ready—The stage when the stack member has completed loading the system- and interface-level
configuration and is ready to forward traffic.
• Master Re-Init—The stage immediately after a stack master re-election and a different stack
member is elected stack master. The new stack master is re-initializing its configuration. This state
applies only to the new stack master.
• Ver Mismatch—The stage of a switch in version mismatch (VM) mode. VM mode is when a switch
joining the switch stack has a different stack protocol minor version number from the stack 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 becoming a stack master after a stack master election is
Ready -> Master Re-Init -> Ready.
A typical state transition for a stack member in version mismatch (VM) mode is Waiting ->
Ver Mismatch.
