Configuring EtherChannels
These sections describe how to configure EtherChannel interfaces:
• Default EtherChannel Configuration, page 27-7
• EtherChannel Configuration Guidelines, page 27-8
• Configuring Layer 2 EtherChannels, page 27-8
• Configuring EtherChannel Load Balancing, page 27-10
• Configuring the PAgP Learn Method and Priority, page 27-11
Note Make sure that the interfaces are correctly configured (see the “EtherChannel Configuration Guidelines”
section on page 27-8).
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.
Default EtherChannel Configuration
Table 27-2 shows the default EtherChannel configuration.
Note The basic version of Etherchannel, which has to be manually configured, is not supported on the Catalyst
2950 LRE ports; the PAgP-enabled version is supported.
Table 27-2 Default EtherChannel Configuration
Feature Default Setting
Channel groups None assigned.
PAgP mode No default.
PAgP learn method Aggregate-port learning on all interfaces.
PAgP priority 128 on all interfaces. (Changing this value has no effect.)

source-MAC address of the incoming packet.
