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.

Hi, yes I am positive.

I have just looked at the current stack config and both switches are currently set to:

License level restriction :

X450 show license:
Enabled License Level:
Edge
Enabled Feature Packs:
None
Effective License Level:
Edge

X650 show license:
Enabled License Level:
Core
Enabled Feature Packs:
None
Effective License Level:
Core

I was changing settings and have set the stacking licence levels accordingly for each switch, but this hasn't been applied yet because they have not been rebooted. Is there a way to unset this?

Would it be that the master can be a lower level than the backup-master? As your example is the other way around.

Both switches are running 12.3.3.6

Below is the information from the EXOS 15.4 concept guide page # 162

"If the stack is using the Advanced Edge license and you attempt to add a master-capable node thatis using an Edge license, the node does not become operational and shows as Failed with a License Mismatch reason when using the show slot {slot{detail} | detail}command."

Yes, I am correct. Are you sure you have configured the stack with core license and edge license on backup and master switch respectively?

Thanks for the reply. I looked at documentation and have seen it say that the software versions must be the same, but no details about the licenses. Are you sure this is correct? I don't want to reboot the current master and then to find it won't join the stack again after reboot.

I wonder how did you build the stack with core license and edge license on backup and master switch respectively.

As per as I know, to build the stack atleast master and backup slot should have same license level. Here, you can turn on the master-capability on X650 switch and turn off the master capability on X450 switch. Reboot the X450 switch. It will join as a standby switch.
