Hi there,
We have a live stack with 4 Cat 3750 switches of mixed varieties. Switch 1 crashed the other day and didn't come back up. A power reset brought the switch online again, and switch 2 is now running as the stack master. We are going to replace switch 1 in a staged approach to minimise client downtime. Switch 1 is a ws-c3750-48ts and we will be replacing it with a ws-c3750g-48ts. I will be pre-provisioning and installing the new switch into the stack as switch 5 and configuing the ports to be the same as switch 1. The cables will then be moved over from switch 1 to switch 5 so the changeover time should be minimal. When all cutover, I'll power down switch 1, reconfigure the stack cables and remove switch 1 from the stack.
My question is to what occurs next. If I perform a 'no switch 1 provision ws-c3750-48ts' will I be left with switch 2 through to 5 (ie no switch 1)? I can live with this moving forward. I know I can renumber switch 5 to be switch 1 if I want, but my understanding is that I have to reload the member switch which is something I'd like to avoid at this stage. In my reading, I saw the statement - "Note: You cannot use the switch current-stack-member-number renumber new-stack-member-number global configuration command on a provisioned switch. If you do, the command is rejected." I'm a bit confused by this statement, I'm assuming that it is saying that if I do as above but don't issue the 'no switch 1 provision' command, I cannot renumber switch 5 to switch 1 but as long as I use the 'no switch 1 provision' command first, I can renumber switch 5 to switch 1? Will all of my switch 5 port configuration information and any associated references (eg port-channel configuration etc) be changed from gi5/0/x to gi1/0/x if I do renumber?
Thanks in advance,
Mark J.
