Configuring EtherChannels
This example shows how to configure an EtherChannel. It assigns two ports as static-access ports in
VLAN 10 to channel 5 with the PAgP mode desirable:
VLAN 10 to channel 5 with the PAgP mode desirable:
Switch# configure terminal
Switch(config)# interface range gigabitethernet0/1 -2
Switch(config-if-range)# switchport mode access
Switch(config-if-range)# switchport access vlan 10
Switch(config-if-range)# channel-group 5 mode desirable non-silent
Switch(config-if-range)# end

Configuring Layer 3 EtherChannels
To configure Layer 3 EtherChannels, you create the port-channel logical interface and then put the
Ethernet ports into the port-channel as described in the next two sections.

Creating Port-Channel Logical Interfaces
When configuring Layer 3 EtherChannels, you should first manually create the port-channel logical
interface by using the interface port-channel global configuration command. Then you put the logical
interface into the channel group by using the channel-group interface configuration command.

interface into the channel group by using the channel-group interface configuration command.
Note
To move an IP address from a physical port to an EtherChannel, you must delete the IP address from the
physical port before configuring it on the port-channel interface.

Beginning in privileged EXEC mode, follow these steps to create a port-channel interface for a Layer 3
EtherChannel. This procedure is required.
