LACP system priorities determine the sequence in which devices at two ends of an Eth-Trunk select active interfaces to join a LAG.
In order for a LAG to be established, both devices must select the same interfaces as active interfaces. To achieve this, one device (with a higher priority) is responsible for selecting the active interfaces. The other device (with a lower priority) then selects the same interfaces as active interfaces.
The system view is displayed.
The LACP system priority is set.
In priority comparisons, numerically lower values have higher priority. By default, the LACP system priority is 32768.
The end with a smaller priority value functions as the Actor. If the two ends have the same LACP system priority, the end with a smaller MAC address functions as the Actor.
