lacp port-priority
To configure the port priority for the Link Aggregation Control Protocol (LACP), use the lacp port-priority
command in interface configuration mode. To return to the default setting, use the no form of this command.

Usage Guidelines
The lacp port-priority interface configuration command determines which ports are bundled and which ports
are put in hot-standby mode when there are more than eight ports in an LACP channel group.
An LACP channel group can have up to 16 Ethernet ports of the same type. Up to eight ports can be active,
and up to eight ports can be in standby mode.
In port-priority comparisons, a numerically lower value has a higher priority: When there are more than eight
ports in an LACP channel group, the eight ports with the numerically lowest values (highest priority values)
for LACP port priority are bundled into the channel group, and the lower-priority ports are put in hot-standby
mode. If two or more ports have the same LACP port priority (for example, they are configured with the
default setting of 65535), then an internal value for the port number determines the priority.
The LACP port priorities are only effective if the ports are on the switchthat controls the LACP link. See
the lacp system-priority global configuration command for determining which switch controls the link.
Note
Use the show lacp internal privileged EXEC command to display LACP port priorities and internal port
number values.
For information about configuring LACP on physical ports, see the configuration guide for this release.
