Pagp Learn-Method - Cisco ME 3400 Command Reference Manual

Chapter 2 Cisco ME 3400 Ethernet Access Switch Cisco IOS Commands

pagp learn-method

Use the pagp learn-method interface configuration command to learn the source address of incoming
packets received from an EtherChannel port. Use the no form of this command to return to the default
setting.
PAgP is available only on network node interfaces (NNIs) and enhanced network interfaces (ENIs).
Note
Syntax Description
aggregation-port
physical-port
Defaults The default is aggregation-port (logical port channel).
Command Modes Interface configuration
Command History Release
12.2(25)EX
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 learn-method. Learn must be configured to
the same method at both ends of the link.
The Cisco ME switch supports address learning only on aggregate ports even though the physical-port
Note
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.
OL-9640-10
pagp learn-method {aggregation-port | physical-port}
no pagp learn-method
Specify address learning on the logical port-channel. The switch sends
packets to the source using any of the ports in the EtherChannel. This setting
is the default. With aggregate-port learning, it is not important on which
physical port the packet arrives.
Specify address learning on the physical port within the EtherChannel. The
switch sends packets to the source using the same port in the EtherChannel
from which it learned the source address. The other end of the channel uses
the same port in the channel for a particular destination MAC or IP address.
