Haven't tried it since moving to 9.0 and 9-STABLE on those three boxes. igb+lagg doesn't work for him on 9.0. Although, I don't recall if non-LACP options were tried earlier in this thread, or if it's just the LACP mode that's failing. If one mode works (say failover) and LACP mode doesn't, that "seems to" point to lagg. I'll see if I can free up an igb port on my 9.0 and 9-STABLE boxes to test this with as well. -- Freddie Cash fjwcash@gmail.com
