3750x switch stack numbering and priority question

[bradleywilliams5086]

I have a stack of 3, with 2 as the Master.

I'm required to take out the current master.

My goal is to renumber/prioritize the switch stack and schedule it to reload overnight prior to hardware removal, to prevent the switch from reloading when I physically remove the old master during business hours.

1>1

2m>out

3>2m

My question is if the priority is set on the (1)general switch stack#, (2)current switch in stack #, or (3)future switch in stack#?

i.e. do I do...

(1)

switch 2 priority 15

switch 3 priority 1

switch 2 renumber 3

switch 3 renumber 2

(2)

switch 2 priority 1

switch 3 priority 15

switch 2 renumber 3

switch 3 renumber 2

(3)

switch 2 renumber 3

switch 3 renumber 2

switch 2 priority 1

switch 3 priority 15

Can you post the output of "sh switch"?

[bradleywilliams5086]

switch     role              priority

1         member              1

*2       master                 12

3         member               3

I would give switch-1 the highest priority (15), switch-2 (current master 6 and keep switch 3 the same (3).

After reboot, switch-1 will be the master, once you replace switch-2 give it 6 again and than switch 3 still stays the same.Basically the numbers stay the same after the reboot and after the switch replacement..

sw-1 15 master

sw-2 6 member

sw-3 3 member

It is for a switch removal.  No replacement.  I do not want to elect 1 as the master, as I need to retain the master on switch 2 in the stack, and I am trying to prevent the need of a 2nd reboot.

[Reza Sharifi · Accepted solution]

Than this should do it. Hopefully, all can be accomplished with one reboot. I would have a long enough maintenance window for a second reboot just in case.

switch 2 priority 1

switch 3 priority 15

switch 2 renumber 3

switch 3 renumber 2

Thank you very much.

Worked great.

Needed a secondary reboot anyways, as 1 of the stacking cables was showing down down after swapping, but that was done after hours.

Thanks for the feedback!

Glad to know you are good on this.
