4.6.4.1 LACP System Priority
Every LACP device needs to have a globally unique system identifier. This globally unique system
identifier is formed by combining a switch’s MAC address and LACP system priority.
LACP system priority is also used to decide the active member ports of a port channel. When more than
eight member ports are configured, the switch that has a low system priority value decides the active
member ports. If both end devices have the same LACP system priority, the device with the numerically
lower MAC address will get to decide the active member ports.
The default LACP system priority value is 32768.
Follow the steps below to modify the LACP system priority.
