To verify that your stack is configured as you intended, issue any or all of the commands described here.
The show slot and show stacking commands contain stacking configuration information, including the state of the slot. These commands are also helpful when debugging stacking problems.
The show slot command shows the states of the nodes as they move from the empty to operational state.

The asterisk (*) that precedes the node MAC address indicates the node to which you are logged in. The node MAC address is the address that is factory assigned to the stackable switch.
The slot number shown is the number currently in use by the related node. Because slot number configuration only takes effect during node initialization, a change in configured value alone does not cause a change to the slot number in use.
If a node role has not yet been determined, the node role indicates <none>. In a ring topology, the node on which this command is executed is always the first node displayed. In a daisy chain, the ends of the daisy chain are the first and last nodes displayed.
Even though the stack topology could be a ring, the active topology could be a daisy chain because it does not contain every node in the stack topology.
If the node on which this command is being executed is not active, the stacking topology is replaced with a line similar to this one:
This node is not in an Active Topology.
Note
It is possible for a node to be in stabilizing or waiting state and still be in the active topology.Slot-1 Stack.2 # show stacking configuration Stack MAC in use: 02:04:96:26:6b:ed Node Slot Alternate Alternate MAC Address Cfg Cur Prio Mgmt IP / Mask Gateway Flags Lic ------------------ --- --- ---- ------------------ --------------- --------- --- *00:04:96:26:6b:ed 1 1 Auto <none> <none> CcEeMm--- -- 00:04:96:34:d0:b8 2 2 Auto <none> <none> CcEeMm--- -- * - Indicates this node Flags: (C) master-Capable in use, (c) master-capable is configured, (E) Stacking is currently Enabled, (e) Stacking is configured Enabled, (M) Stack MAC in use, (m) Stack MACs configured and in use are the same, (N) Stack link protocol Enhanced in use, (n) Stack link protocol Enhanced configured, (i) Stack MACs configured and in use are not the same or unknown, (-) Not in use or not configured License level restrictions: (C) Core, (A) Advanced edge, or (E) Edge in use, (c) Core, (a) Advanced edge, or (e) Edge configured, (-) Not in use or not configured

If you do not specify any node, the output is generated for all nodes in the stack topology. If the specified node does not exist, an error message appears.
The slot parameter is available only in stacking mode. The node-address parameter is always available.
Current information represents stacking states and configured values that are currently in effect. Configured information is that which takes effect at node reboot only.
The roles values are Master, Backup, Standby, and none. License level restrictions are Edge, Advanced Edge, or Core.
