Cisco stack

From Ever changing code

This is example of manipulating of Cisco stack-able switches. 8x switches have been stacked up but now are de coupled and need to have stacking provisioning removed as for example still showing the stack port numbering FastEthernet1/0/1 to FastEthernet8/0/24 When removing/renumbering provisioned switches remember to:

renumber, Ready switch -> in place of Provisioned switch
removing, renumber first then remove the highest Provisioned switch eg. 8 -> 7. Removing lower switch number then Ready switch can cause unpredictable behavior.

Renumber switch 2 -> switch 1, then reload to take affect

WARNING: Changing the switch number may result in a
configuration change for that switch.
The interface configuration associated with the old switch
number will remain as a provisioned configuration.
