Usage Guidelines You must assign each port in the switch a port priority that can be specified automatically or by entering
the lacp port-priority command. The port priority is used with the port number to form the port
identifier. The port priority is used to decide which ports should be put in standby mode when there is a
hardware limitation that prevents all compatible ports from aggregating.
Although this command is a global configuration command, the priority value is supported only on port
channels with LACP-enabled physical interfaces.This command is supported on LACP-enabled
interfaces.
When setting the priority, the higher numbers indicate lower priorities.
Examples This example shows how to set the priority for the interface:
Switch(config-if)# lacp port-priority 23748
