The LACP support on a vSphere Distributed Switch lets network devices to negotiate automatic bundling of links by sending LACP packets to a peer. However, the LACP support on a vSphere Distributed Switch has limitations.
The LACP support is not compatible with software iSCSI multipathing.
The LACP support settings are not available in host profiles.
The LACP support is not possible between nested ESXi hosts.
The LACP support does not work with the ESXi dump collector.
The LACP control packets (LACPDU) do not get mirrored when port mirroring is enabled.
The teaming and failover health check does not work for LAG ports. LACP checks the connectivity of the LAG ports.
The enhanced LACP support works correctly when only one LAG handles the traffic per distributed port or port group.
The LACP 5.1 support only works with IP Hash load balancing and Link Status Network failover detection.
The LACP 5.1 support only provides one LAG per distributed switch and per host.
