Removing 3750X Stack Switch and reconfiguring the Stack

Hello there,

 

I have a 5x 3750X stack already in production. Due to lack of length of some cables, the most important connections were connected from the bottom up. Now i have to take a switch out of the stack and the only switch i can take out is the 1st one.

 

My issue is, when i take out the 1st switch, i want the configuration to "adapt" to the new stack numbering. Meaning the 2nd switch configuration passes to the 1st.. the 3rd to the 2nd and so on.

 

When i remove the 1st switch of the stack, i lose the configuration of the switch when i do the no switch 1 provision command. (which is what i want)

After that i renumber switch 5 to 4, 4 to 3, 3 to 2 and 2 to 1.

With this i actually stay with a 4 switches stack by order as expected.


Problem is, the configuration that was on port Gi2/0/1, remains on port Gi2/0/1 instead of moving up (as the switch did when i renumbered it) to Gi1/0/1.

Is there any way to move the configuration to the new ports?

 

I've tested different ways but am not able to find an answer. From what i understood the switch X provision command maintains the configuration until the no of that command is issued. Is there a way of recovering that part of the configuration and reapplying it to another switch?

 

If you have any doubts with what i just tried to explain please let me know

 

Thank you in advance,

 

João Santos

Hi,

So, right now for switch-1 the ports starts from 2/0/1... and so on right?

As far as I know, you can't change the config to go from 2/0/1... to 1/0/1....without breaking the stack and re-prevision it again.

The easiest way is to renumber it back to the original numbering, so that port 2/0/1 is on switch-2, if not it get confusing.
