Sounds like a good reason to change this. I believe the initial choice was rather arbitrary. Btw - I'd go with active-backup, this is the safest approach working with all switches etc. 802.3ad requires switch support. The initial list order probably came from this order: https://en.wikipedia.org/wiki/Link_aggregation#Driver_modes If active-backup is a safer choice I'll trust your word on it. Another reason might have been that round-robin gives both load balancing and fault tolerance, and that kind of gave you a good outcome if you wasn't super good at what all the modes does. But we do not want the defaults to result in something that just breaks setups, so I'm good at switching to active-backup. This will be part of 0.113 https://github.com/cockpit-project/cockpit/pull/4653 No test yet as far as I can tell. A test should be added here: https://github.com/cockpit-project/cockpit/blob/master/test/verify/check-networking#L191 Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
