Configuring EtherChannels
These sections describe how to configure EtherChannel on Layer 2 interfaces:
• Default EtherChannel Configuration, page 28-9
• EtherChannel Configuration Guidelines, page 28-9
• Configuring Layer 2 EtherChannels, page 28-10 (required)
• Configuring EtherChannel Load Balancing, page 28-12 (optional)
• Configuring the PAgP Learn Method and Priority, page 28-13 (optional)

Note Make sure that the interfaces are correctly configured. For more information, see the “EtherChannel
Configuration Guidelines” section on page 28-9.
Note After you configure an EtherChannel, configuration changes applied to the port-channel interface apply
to all the physical interfaces assigned to the port-channel interface, and configuration changes applied
to the physical interface affect only the interface where you apply the configuration.
