3750 stacking problems with new switch

Hi

At a customer i've tried to add a new 3750 switch til a running stack.

I used the following proccess:

1. connect stack cables to the new switch

2. bootup new switch.

Normaly the new switch will become a member of the stack, but here, the switch says its the stack master. I can see that the stack port from the old swtiches connecting the new is up.

The only way i could make it work was to provisioning the new switch as switch nr x, save, power off and then connecte it and boot it up.

The IOS i the same on all switches.

3750 stacking problems with new switch

Hi

Could you please check the priority in both the switches?

from the show sw detail output you can see the priority configured in both the switches.

++ Higher the priority of the switch more chances of becoming the master.

To change the priority,

switch priority <1-15>

++ The new priority will take into effect only if the switch is reloaded.

By default the priority would be 1.

Hope this answers your question.

Cheers
