To aggregate the bandwidth of multiple physical NICs on hosts, you can create a link aggregation group (LAG) on the distributed switch and use it to handle the traffic of distributed port groups.
Newly created LAGs do not have physical NICs assigned to their ports and are unused in the teaming and failover order of distributed port groups. To handle the network traffic of distributed port groups by using a LAG, you must migrate the traffic from standalone uplinks to the LAG.
Verify that for every host where you want to use LACP, a separate LACP port channel exists on the physical switch. See LACP Support on a vSphere Distributed Switch.
Verify that the vSphere Distributed Switch where you configure the LAG is version 5.5 or 6.0.
Verify that enhanced LACP is supported on the distributed switch.
