Hi - Yeah Sorry, I'm in forums a lot, Usually on the answering side at Cisco and Experts Exchange, 2 days is a long time for me !
Anyway, to answer, LACP IS setup on the Synergy it configures it by default when you create an 'uplink group', with no interaction. The latest firmware (which I put on last week, let's you change the LACP load balancing algorythm, but its on 'select based on source ip and mac, and destination ip and mac' anyway.
