Couple different options: - create a single lagg0 device using all port NIC ports - create your lagg0 using A1 + B2, and your lagg1 using A2+B1 Both of those will give you fail-over support for losing a single NIC port, an entire NIC, or an entire switch. Of course, if your switched aren't stacked to support LACP across them, then you will be limited to a single links bandwidth. But you will be extremely safe. :) -- Freddie Cash fjwcash@gmail.com
