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.

Remove the stacking cable from the switch which got stuck on pending-AAA.
perform hard reboot and go into bootrom(tap space bar while booting the switch). execute the command

1)config none...........This command will remove the config from the stack.
2)reboot as MASTER-CAPABLE......It will reboot the switch after enabling the master-capable.

once the switch boots normally, try to add new node into existing stack.

Hi Sumit, I ran the commands which you said an am now slot 1 will not rejoin the stack.

I had master-capability off for slot 1 and rebooted it

I now get the login prompt (pending-AAA) login:

I have tried the REBOOT AS MASTER-CAPABLE but this is not working.

If you can provide some help that would be great.

show stack:

Stack Topology is a Daisy-Chain

Thanks, i'll do this and let you know how it turns out. I have some config changes to make first before I can proceed.

[Sumit_Tokle]

execute the command "configure stacking slot 1 master-capability off"

and then reboot the slot 1 using command reboot slot 1. it should join as standby switch.

Btw, I reset the priorities again so X450 would have a higher priority again than X650, that is why it looks like that above.
