change switch virtual domain id on an already configured VSS

[Steffen Lindemann]

I have two VSS clusters back to back via etherchannel (not LACP nor PAgP).

I have realised that its not a good idea to have the same domain ID on the two VSS'es.

So my question is, can I in a smart way change the "switch virtual domain 10" to e.g. 20 on one of the clusters. The setup is not yet in production, so I am able to reboot it.

Hello Steffen,

Please follow the steps below :

1) change the virtual domain id  " VSS(config)#switch virtual domain 20 "
2) Issue "switch convert mode virtual" command
3) After you do that, switch will save the config and reload it 

Your task is complete and the switch will come up with new domain id

Since, your device is not in production you can follow the above procedure and yes its not advisable to have same Domain ID on two clusters which are connected.

cheers.

worked like a charm, thank you.

The output from CLI:

VSS(config)#switch virtual domain 20
VSS#switch convert mode virtual

Virtual Domain ID change only, saving
the config and reloading the switch
Do you want to proceed? [yes/no]: yes
Building configuration...

And the result from a show run:

switch virtual domain 20
switch mode virtual
