Yes, using LACP trunking on the switch and lagg(4). I'll have to double-check the exact switch models but I believe one is a 2910 and the other is a 28-something. I've also done it using load-balance and fail-over using unmanaged switch ports. Never used round-robin, though. --=20 Freddie Cash fjwcash@gmail.com
