I'm interested in using lagg(4) to provide failover from a main wireless link to a backup link. Unfortunately, one of the common failure modes, when a link fails, is for the Ethernet port on the radio to stay up but not pass any traffic. Does lagg(4) test the link, by actually trying to send packets, to determine if the link has failed? Or does it rely upon the Ethernet link losing "carrier"? --Brett Glass
