According to this doc you can set the switch to use dst mac, src mac, or a combination of the two on the 3560.

From my read, most link aggregation will use mac addresses to hash and determine which port to forward thru. I belive however I have the worst case scenario since traffic IN will have 1500 different source macs but 1 destination, and traffic OUT will have 1 source mac and 1500 destination macs. Even worse, this traffic is PPPoE and not IP, eliminating any sort of ip based selection criteria. This means, to my read anyways, I would have course grained load sharing in 1 direction, sort of defeating the point here. I was wondering if anyone had any ideas for this platform and suggestions how I might get better performance in this situation.
