1 Each DLMP client is associated with exactly one DLMP port.
The remaining ports act as available ports for the DLMP clients, but you cannot configure
these available ports.
2 The aggregation spreads its VNICs across all ports.
However, individual VNICs cannot spread the load on multiple ports.
3 DLMP aggregations must always use an intermediary switch to
send packets to other destination systems. However, no switch configuration is required for
DLMP.
