Cisco ME 3400 Ethernet Access Switch Cisco IOS Commands
pagp port-priority
Use the pagp port-priority interface configuration command to select a port over which all Port
Aggregation Protocol (PAgP) traffic through the EtherChannel is sent. 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. Use the no form of this command to return to the default setting.
Note
PAgP is available only on network node interfaces (NNIs) and enhanced network interfaces (ENIs).

Usage Guidelines
If the interface is a user network interface (UNI), you must enter the port-type nni or port-type eni
interface configuration command before configuring pagp port-priority.
The physical port with the highest operational priority and that has membership in the same
EtherChannel is the one selected for PAgP transmission.
Note
The Cisco ME switch 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 switch hardware, but they are
required for PAgP interoperability with devices that only support address learning by physical ports.
When the link partner to the Cisco ME switch is a physical learner, we recommend that you configure
the switch as a physical-port learner by using the pagp learn-method physical-port interface
configuration command and to 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.
