Well, if I create lagg0 A1 + B2 and lagg1 A2+B1 , I'll end up with 2 laggs. How though, to I bind my vlan interfaces to *both* laggs ? I'm not sure that can be done. Currently and in the interim, I've put our WAN vlan on lagg0 and our 2 internal vlans on lagg1 ;) _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[email protected]"
