I've not had to setup a new bond in our environment, but if I was going to do it, clearly a maintenance window would be arranged and then I would likely do the below (suggest you test this first).
- Snapshot (Optional)
- Ensure you set any comments on the interfaces 'a' and 'b' first, ensure the interfaces do not have any other configurations on their such as IP addresses, comments are fine and of course ensure the interface is enabled.You may wish to set the rx buffer but that's outside the scope of the question.
add bonding group <x>
add bonding group <x> interface <a>
add bonding group <x> interface <b>
set bonding group <x> mode 8023AD
set bonding group <x> comments "New Bonding group example"
set interface bonding group <x> on
set bonding group <x> primary <a>
I believe next you would need to update the topology in VSX Cluster via the Management DMS, install database and the push the configuration out to the cluster.
Then I believe the bond should be available for use, now clearly there are switching element involved so you need to ensure this is all prepared.
Assuming you are running R80.30+ b.t.w
