As far as I know it is not possible to create two 802.3ad and run active passive between the two trunks ? (since I also need failover and you cant create one 802.3ad bundle with one interface in each switch)
The point of this thread for my part is to know if it is possible to bind traffic to separate ethernetcards using separate ips or maybe automaticaly as the EQ does it. (all iscsi traffic is in one subnet så the issue with return traffic going through one adapter)
