Configuring EtherChannels
These sections describe how to configure EtherChannel interfaces:
• Default EtherChannel Configuration, page 25-8
• EtherChannel Configuration Guidelines, page 25-8
• Configuring Layer 2 EtherChannels, page 25-9
• Configuring EtherChannel Load Balancing, page 25-11
• Configuring the PAgP Learn Method and Priority, page 25-12
Note Make sure that the interfaces are correctly configured (see the “EtherChannel Configuration Guidelines”
section on page 25-8).
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.
