My Network Lab: Renumbering a Cisco 9300 Switch

Here's a Cisco link to renumber a Cisco switch stack. Validate the current switch stack number using the show switch command. In my scenario, it's only a single switch which was pulled out from a previous switch stack. I had to renumber the switch using the privilege command switch <current-number> renumber <new-number> in order to display the correct interface number. A reload is required afterwards.

C9300#switch ?
<1-16> Switch Number
clear Reset the switch mode to N+1

C9300#switch 2 ?
priority Set the priority of the specified switch
renumber Renumber the specified switch number
ring-speed Set the switch ring speed to low/high
role Set the new switch mode of the Switch
stack Stack port enable or disable

C9300#switch 2 renumber ?
<1-16> New number of the Switch

C9300#switch 2 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. New Switch Number will be effective after next reboot. Do you want to continue?[y/n]? [yes]: yes

C9300#reload

System configuration has been modified. Save? [yes/no]: y

The switch was already in the correct number/order but it still had Gi2/0/x interfaces.

It still had the switch <number> provision <platform> command, which is used to preconfigure interfaces before physically stacking the switch. I just negate using switch 2 provision c9300-48p to remove the Gi2/0/x interfaces. You'll need to reload to take effect.

C9300#show run | i switch
switch 1 provision c9300-48p
switch 2 provision c9300-48p
C9300#
C9300#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
C9300(config)#no switch 2 provision c9300-48p
C9300(config)#end
C9300#write memory
Building configuration...
[OK]
C9300#reload
Reload command is being issued on Active unit, this will reload the whole stack
Proceed with reload? [confirm]
