We currently have a stack of Catalyst 9300, like this :
We plan on adding a 4th switch, SW4, but in between SW2 and SW3. This would give:
My question is : would that impact our configuration ? What I mean is that as it stands, port 1 on SW3 has configuration and is referenced as Gi3/0/1. If SW3 now becomes the switch at the bottom, would we still address the port as Gi3/0/1 or as Gi4/0/1 ? And would the Gi3/0/1 configuration now be applied on the newly added switch in the middle, or remain active on the switch at the bottom ?
Would we need to renumber one of the switch ?
