Dismantling a Stack
-
Issue the show
stacking stack-ports command to see if any nodes in the stack are using
alternate stacking ports.
In the following example, the switches in slots 1 and 2 have 24 data ports, and the switches in slots 3 and 4 have 12 data ports. The numbers in the Select column show that all ports in this stack are alternate stacking ports, not regular data ports.

-
For every non-master node in the stack that is using
alternate stacking ports, log into the node and issue the unconfigure stacking-support command.
Do not reboot any of the switches.
If step 1 showed that no alternate stacking ports are in use, skip this step.
Note
- This command resets the ports so that they are no longer dedicated for use as stacking ports.
- It is not necessary to unconfigure stacking-support on the master node.
- If a node is a member of the active topology, you can log in to other nodes using the telnet slot slot-number {no-auto-login} command. Otherwise, you need access to the node's console port, or you need to log in through a management network.
-
Log into the master node and issue the unconfigure switch all command.
After this command is entered, the configuration file is deselected, all stacking parameters are reset to factory defaults, and all nodes in the active topology reboot. In effect, this sets all nodes back to the factory default configuration, thus allowing each switch to be redeployed individually.
- Restore the saved configuration for each switch, if applicable.
