Configuring Port Channel Logical Interfaces for Layer 3 EtherChannels

Note •

•
To create a port channel interface for a Layer 3 EtherChannel, perform this task:
Command
Step 1
Router(config)# interface port-channel number
Router(config)# no interface port-channel number
Step 2
Router(config-if)# ip address ip_address mask
Step 3
Router(config-if)# end
Step 4
Router# show running-config interface
port-channel number
When creating the port channel interface, the group number can be one of the following:

This example shows how to create port channel interface 1:
Router# configure terminal
Router(config)# interface port-channel 1
Router(config-if)# ip address 172.32.52.10 255.255.255.0
Router(config-if)# end
This example shows how to verify the configuration of port channel interface 1:
Router# show running-config interface port-channel 1
Building configuration...
Current configuration:
!
interface Port-channel1
ip address 172.32.52.10 255.255.255.0
no ip directed-broadcast
end

When configuring Layer 2 EtherChannels, you cannot put Layer 2 LAN ports into manually created
port channel logical interfaces. If you are configuring a Layer 2 EtherChannel, do not perform the
procedures in this section (see the
When configuring Layer 3 EtherChannels, you must manually create the port channel logical
interface as described in this section, and then put the Layer 3 LAN ports into the channel group (see
the "Configuring Channel Groups" section on page
To move an IP address from a Layer 3 LAN port to an EtherChannel, you must delete the IP address
from the Layer 3 LAN port before configuring it on the port channel logical interface.
