Configuring EtherChannel
Configuring port channels using EtherChannel

This table shows the steps to configure and verify an EtherChannel interface.  – 

Configuring Layer 3 Etherchannel
This table shows the steps to configure and verify a Layer 3 EtherChannel interface.  – 

Verifying EtherChannel
Use the show interfaces [interface] [num] etherchannel command to display information about the port channel and the specific EtherChannel interfaces.

Example: Verifying the Configuration of a Layer 3 EtherChannel

Switch#show interfaces fastethernet 5/4 etherchannel

Example: Verifying the Configuration of a Layer 2 EtherChannel
Two examples show how to verify the configuration of Fast Ethernet interface 5/6:

Switch#show running-config interface fastethernet 5/6
Switch#show interfaces fastethernet 5/6 etherchannel

Example: Verifying Port-Channel Configuration
Use the show etherchannel command to display port-channel information after configuration.

Switch#show interfaces gigabitethernet 0/9 etherchannel

This example shows how to verify the configuration of port-channel interface 1 after the interfaces have been configured:

Switch#show etherchannel 1 port-channel

This example shows how to verify the configuration of port-channel interface 2 (a Layer 2 EtherChannel) after the interfaces have been configured:

Switch#show etherchannel 2 port-channel
