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.
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.
The display also includes stack MAC-persistency wait-time if persistent MAC address is enabled.
Examples
This example shows how to display summary information about a switch stack:
Switch> show switch
Switch/Stack Mac Address : 001b.540c.5d00

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.
SDM Mismatch—A switch in Switch Database Management (SDM) mismatch mode. SDM
mismatch is when a member does not support the SDM template running on the 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.
