3750 Stack setup

I am trying to setup stacking so i can have a permanent master if the switches go down. I just can't seem to get it to work. I connected the stack cables aand i only have one switch powered on right now. Below is the output of the sh switch command. Can someone please tell me the command i should enter. I am not sure why it's saying *2 is the master when i only have this switch powered on?

sh switch

Switch#  Role   Mac Address     Priority Version  State
----------------------------------------------------------
1       Member 0000.0000.0000     0      1       Provisioned
*2       Master 30e4.db06.2680     1      1       Ready

core1#

Any help would be greatly appreciated.

Thanks,

Lake

Hi Lake,

Are you sure there were no stack related configs present in that switch before it was powered on ??

The switch which you have powered on is identified as 2nd switch in the stack which is a master.......its not necessary that your master switch has to be numbered as 1. It can be any numbers.........I am not sure why it has considered it as switch number 2.

Incase you want to keep as stack 1. Then you can do these things.

- Power on the other switch then switch 1 status will be shown as "Ready" if everything goes well.....(all will go well if you have same IOS versions and with default priority)

- Renumber the member switch 1 to 3 using command switch 1 renumber 3

- Reload member Switch 1 (that is the switch that was powered on 2nd)

- Renumber master switch 2 to 1 using command switch 2 renumber 1

- Save configurations to nvram

- Power Off member Switch

- Reload the master switch

- Renumber member switch 3 to 2 using command switch 3 renumber 2

- Power on member switch

- Save configurations to nvram

Not sure if you might now need a reload for both master and member switch. (you can reload both and see if the numbers doesnt get changed from 3 to 2)

Now your desired master switch will be shown as switch stack 1.
