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
