Chapter 8: Port Trunking
Section I: Basic Operations 132
The binary values would be:
9 = 1001
3 = 0011
Applying the XOR rules above on the last three bits would result in 010.
A examination of the table above shows that the packet would be
transmitted from port 9.
Port trunk mappings on an AT-8500 Series switch can consist of up to
eight ports. This corresponds to the maximum number of ports allowed
in a static trunk and the maximum number of active ports in an LACP
trunk. (Inactive ports in an LACP trunk are not applied to the mappings
until they transition to the active status.)
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.
