We have a switch stack with six Cisco 3850 switches in it and for some reason the physical order of the switches in the cabinet and the switch number are not in sync. This is causing confusion; when an engineer physically plugs a port into switch 3 they have to remember to configure interface Gi6/0/x instead of G3/0/x.
My experience of renumbering switches is that it requires a reboot to take affect. Given that stack switch supports a 24/7 operation, arranging downtime will be hard and could take several months. However the area is often prone to power-cuts. Is there any reason why I shouldn't just change the switch numbers now and if the switches go down due to power issues before we can reboot them in a change window, they will reboot with the correct numbers?
