Default lacp 802.3ad works with mac based hashes to loadbalance traffic. So single host (mac) will be transfered by one ethernet adaptor as you have seen. > > I haven't changed any kernel configuration, nor sysctl's - am I missing > sth ? There are tuneables, i think, to change the hash from mac source : dest hash to session tcp source+port: dest:port but these might need also configuring on switch/network.
