Configuring EtherChannels
Figure 30-3 Load Distribution and Forwarding Methods
Use the option that provides the greatest variety in your configuration. For example, if the traffic on a
channel is going only to a single MAC address, using the destination-MAC address always chooses the
same link in the channel; using source addresses or IP addresses might result in better load balancing.
Configuring EtherChannels
These sections describe how to configure EtherChannel interfaces:
• Default EtherChannel Configuration, page 30-8
• EtherChannel Configuration Guidelines, page 30-8
• Configuring Layer 2 EtherChannels, page 30-9
• Configuring EtherChannel Load Balancing, page 30-11
• Configuring the PAgP Learn Method and Priority, page 30-12
Note Make sure that the interfaces are correctly configured (see the “EtherChannel Configuration Guidelines”
section on page 30-8).
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.
