I’ve yet to read out how that Cube60G ac 5 Ghz automatic fail over should work. Is there anything in the configuration bonding the 60GHz and 5GHz interfaces together or how that thing is supposed to be achieved?
From my experience, both interfaces (5Ghz and 60Ghz) are running at the same time while bonded, it’s just that the traffic immediately switches to 5Ghz interface with close to no downtime if 60Ghz goes down
