These sections describe how to configure EtherChannel on Layer 2 and Layer 3 ports:
• Default EtherChannel Configuration, page 29-9
• EtherChannel Configuration Guidelines, page 29-9
• Configuring Layer 2 EtherChannels, page 29-10 (required)
• Configuring Layer 3 EtherChannels, page 29-12 (required)
• Configuring EtherChannel Load Balancing, page 29-15 (optional)
• Configuring the PAgP Learn Method and Priority, page 29-16 (optional)

Note Make sure that the ports are correctly configured. For more information, see the “EtherChannel
Configuration Guidelines” section on page 29-9.
Note After you configure an EtherChannel, configuration changes applied to the port-channel interface apply
to all the physical ports assigned to the port-channel interface, and configuration changes applied to the
physical port affect only the port where you apply the configuration.
