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.
The word slave in the output refers to a stack member other than the stack master.
You can use the show switch command to identify whether the provisioned switch exists in the switch
stack. The show running-config and the show startup-config privileged EXEC commands do not
provide this information.

2-468
Ready—The state when the stack member has completed loading the system- and interface-level
configuration and is ready to forward traffic.
Master Re-Init—The state 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 state 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 than the stack master.
SDM Mismatch—The state of a switch in Switch Database Management (SDM) mismatch mode.
SDM mismatch is when a stack member does not support the SDM template running on the stack
master.
Provisioned—The state of a preconfigured switch before it becomes an active member of a switch
stack, or the state of a stack member after it has left the switch stack. The MAC address and the
priority number in the display are always 0 for the provisioned switch.
