Terminology
Link Aggregation:
It is a method to have multiple physical links with the same media and speed
bundled to be a logical link forming a Link Aggregation Group with a group ID. From
the viewpoint of the MAC client, each Link Aggregation Group is an independent link.
There are three cases of link used in the network, which are switch to switch,
switch to station and station to station. Here station may be a host or a router.
Link Aggregation, sometimes called port trunking, has two types of link
configurations: static port trunk and dynamic port trunk.
Static Port Trunk:
When physical links are changed, the administrator needs to manually
configure the switches one by one.
Dynamic Port Trunk:
When physical links are changed, LACP takes over and automatically
reconfigures the trunk group. Administrator does not have to do anything
and may see the trap message of LACP changed in the Network
Management System (NMS).
