Chapter 8: Static and LACP Port Trunks
146 Section I: Basic Operations
You can assign different load distribution methods to different static trunks
on the same switch. The same is true for LACP aggregators. However, it
should be noted that all aggregate trunks within an LACP aggregator must
use the same load distribution method.
The load distribution methods assume that the final three bits of the
source and/or destination addresses of the packets from the network
nodes are varied enough to support adequate distribution of the packets
over the trunk ports. A lack of variation can result in one or more ports in a
trunk being used more than others, with the potential loss of a trunk’s
efficiency and performance.
