Usage Guidelines You must assign each switch that is running LACP a system priority that can be specified automatically
or by entering the lacp system-priority command. The system priority is used with the switch MAC
address to form the system ID and is also used during negotiation with other systems.
Although this command is a global configuration command, the priority value is supported on port
channels with LACP-enabled physical interfaces.
When setting the priority, tthe higher numbers indicate lower priorities.
You can also enter the lacp system-priority command in interface configuration mode. After you enter
the command, the system defaults to global configuration mode.
Examples
The following example shows how to set the system priority:
Switch(config)# lacp system-priority 23748
