Table, info, benchmarks here: http://rhelblog.redhat.com/2014/06/23/team-driver/ [2] On a side note, out of curiosity: does teamd support ARP monitoring if the interface is added to a bridge? The bonding driver doesn't and this is something that always bothered me.

Thus naturally I wanted to use libteam, problem is that still quite a lot of logic is implemented in teamd daemon and not in library. I envision this to work in a following way. networkd will create netdev and enslave interfaces, then it will call systemd dbus API to create instance of teamd for the team device. networkd will then communicate with teamd instance over dbus. Problem I am facing here is not very well designed teamd dbus interface, i.e. you have to pass json config string as parameter. I am not sure we want to get into business of stamping out some json to variable and then passing that string to teamd. It would be much nicer to have v2 of teamd dbus interface. I had a brief discussion about it with teamd maintainer and as always patches are welcome.

AFAIK (and according to wikipedia) you can also use the bonding driver without LACP. https://en.wikipedia.org/wiki/Link_aggregation#Driver_modes and I don't think the teaming driver can do more without LACP than the bonding driver can.

Hi Branko, We do intend to support teaming, but it is still work in progress. Michal might be able to say more about it.
