In this post , we share step by step tested and working procedure on how to change a Cisco switch slot number. A brand new switch from factory usually comes with a Slot number defaulting to 1. However when the switches are used in a Stack , the slot number may get changed or one may even change the slot number manually for identification purposes
Get the switch slot number
Switch # show switch
Switch/Stack Mac Address : 001b.8fb8.6f00

Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#switch 3 renumber 1
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.
