Hi all,
A tip for all who need to configure link aggregation on Mac OS X Tiger 10.4.2, Xserve G5 and 3Com Gigabit Switches (SuperStak III 4924 – 3C17701).
Install latest firmware from 3Com.
Enable LACP on the two ports connected to the Xserve G5 and don’t waste time to manually add the ports to link aggregation set.
