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.

1

To migrate the network traffic of distributed port groups to a link aggregation group (LAG), you create a new LAG on the distributed switch.

2

The new link aggregation group (LAG) by default is unused in the teaming and failover order of distributed port groups. Because only one LAG or only standalone uplinks can be active for distributed port groups, you must create an intermediate teaming and failover configuration, where the LAG is standby. This configuration lets you migrate physical NICs to the LAG ports by keeping the network connectivity up.

3

You have set the new link aggregation group (LAG) as standby in the teaming and failover order of distributed port groups. Having the LAG as standby lets you safely migrate the physical NICs from standalone uplinks to the LAG ports without losing network connectivity.

4

You migrated physical NICs to the ports of the link aggregation group (LAG). Set the LAG as active and move all standalone uplinks as unused in the teaming and failover order of the distributed port groups.
