To select a port over which all Port Aggregation Protocol (PAgP) traffic through the EtherChannel is sent,
use the pagp port-priority command in interface configuration mode. If all unused ports in the EtherChannel
are in hot-standby mode, they can be placed into operation if the currently selected port and link fails. To
return to the default setting, use the no form of this command.

Usage Guidelines
The physical port with the highest priority that is operational and has membership in the same EtherChannel
is the one selected for PAgP transmission.
The controller supports address learning only on aggregate ports even though the physical-port keyword is
provided in the command-line interface (CLI). The pagp learn-method and the pagp port-priority interface
configuration commands have no effect on the controller hardware, but they are required for PAgP
interoperability with devices that only support address learning by physical ports, such as the Catalyst 1900
switch.
When the link partner to the controller is a physical learner, we recommend that you configure the controller
as a physical-port learner by using the pagp learn-method physical-port interface configuration command.
We also recommend that you set the load-distribution method based on the source MAC address by using the
port-channel load-balance src-mac global configuration command. Use the pagp learn-method interface
configuration command only in this situation.
Examples
This example shows how to set the port priority to 200:
Controller(config-if)# pagp port-priority 200
You can verify your setting by entering the show running-config privileged EXEC command or the show
pagp channel-group-number internal privileged EXEC command.
