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.
