Change stacking master in 2 slot stack for BGP

[Michael_Goodlif]

Hi, I have a 2 slot stack currently configured in a daisy chain.

The stack is:
slot 1: X450e-48p (edge license) - Stack master
slot 2: X650-24x (core license) - Backup master

The problem arises due to the fact I now need to set up BGP, but this can only be set up on the master, and the only capable switch is currently the backup.

I have set the stacking priority of slot 2 to 2 and slot 1 to 1, so slot 2 (X650) should take over the master role at the next election. How do I trigger a stacking election process to take place, is there a command for this?

I was thinking one way would be to reboot the current master, and would the backup master would take the master role?

If possible, I'd like the re-election to take place without having to reboot anything.

Any help would be greatly appreciated.

Thanks.

you can paste the output of show switch, show stacking, show slot detail, show slot. show stacking configuration.

At the moment, all external traffic is going through the X650 and internal traffic uses the X450, so that is not a big issue for me. I would love another X650 for redundancy, but at the moment my budget doesn't stretch that far. I also have no support on these switches, so can't upgrade.

Do you think I will have an issue if I reboot the X450 so the X650 is the master? Will it not join the stack again?

We recommend that master and backup should have same software version and license level.

Lets say master is running Core license and you have configured the BGP on it. If in case master switch got rebooted then backup device will become the master but as backup device is not running core license level, it cannot enable the BGP.

It is better to upgrade the stable software version. EXOS 12.3 is end of support by Extreme TAC.
