LACP Limitations on a vSphere Distributed Switch
Link Aggregation Control Protocol (LACP) on a vSphere distributed switch allows network devices to negotiate automatic bundling of links by sending
LACP packets to a peer. However, there are some limitations when using LACP with a vSphere distributed switch.
■ LACP only works with IP Hash load balancing and Link Status Network failover detection.
■ LACP is not compatible with iSCSI software multipathing.
■ vSphere only supports one LACP group per distributed switch, and only one LACP group per host.
■ LACP settings do not exist in host profiles.
■ LACP between two nested ESXi hosts is not possible.
■ LACP does not work with port mirroring.
