[ovs-discuss] lacp to mellanox switch

[Raymond Burkholder]

Based upon documentation, this should 'just' work, but well, it doesn't. The
two slave interfaces seem to always be disabled.  I have the following:

On the server side:

# ovs-vsctl add-bond ovsbr0 bond_mlnx enp8s0f0 enp8s0f1 lacp=active
trunks=64,65

Which has the log entries:
