Agreed - if you want to load balance across multiple interfaces, then use Link Aggregation [on the AIX end] and bonding on the network switch end. Using a non-link aggregated interface and to simply have fail-over then define one interface as primary and the other as backup. Mahesh

Etherchannel is not a true load balanced pipe. You have to carefully select what the hash works against on both AIX side and the switch side. I have my etherchannels setup in aix to on the destination ip addr (tsm clients), and the switch is set for the source ip addr (tsm clients). This is because I'm going from many clients to one tsm server. If you only have a few clients, it's entirelly possible to fill one leg of the channel and leave the other leg not doing much.
