• If the port LACP priority of the link is lower than that of the currently-active
link members, and the number of active members is already at the maximum
number, the link is made inactive, and placed in standby mode.
Setting Port LACP Parameter Settings
The LACP Page displays and enables configuration of the LACP System Priority,
LACP timeout, and LACP port priority. LACP timeout is a per port parameter, and is
the time interval between the sending and receiving of consecutive LACP PDUs.
With all factors equal, when the LAG is configured with more candidate ports than
the maximum number of active ports allowed, the switch selects ports as active
from the dynamic LAG that has the highest priority
NOTE The LACP setting is irrelevant on ports that are not members of a dynamic LAG.
