Appendix C Catalyst 3750 Switch Show Platform Commands
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.
