Admin Key Value assigned to aggregator ports and physical ports that are candidates for joining
a LAG. The LACP implementation uses this value to determine which underlying
physical ports are capable of aggregating by comparing keys. Aggregator ports allow
only underlying ports with admin keys that match the aggregator to join their LAG.
Port Priority Port priority determines which physical ports are moved to the attached state when
physical ports of differing speeds form a LAG. Port priority also determines which
ports will join a LAG when the number of supported ports for a LAG is exceeded.
System Priority Value used to build a LAG ID, which determines aggregation precedence. If there are
two partner devices competing for the same aggregator, LACP compares the LAG
IDs for each grouping of ports. The LAG with the lower LAG ID is given precedence
and will be allowed to use the aggregator.
