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) an internal value for the port number determines the
priority.
Note
The LACP port priorities are only effective if the ports are on the switch that controls the LACP link.
See the
lacp system-priority
global configuration command for determining which switch controls the
link.
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 “Configuring EtherChannels”
chapter in the software configuration guide for this release.
