To create a port-channel interface for a Layer 3 EtherChannel, perform this task:

This example shows how to create port-channel interface 1:

Switch# configure terminal 

Switch(config)# interface port-channel 1 

Switch(config-if)# ip address 172.32.52.10 255.255.255.0 

Switch(config-if)# end 

This example shows how to verify the configuration of port-channel interface 1:

Switch# 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

Switch#

To configure physical interfaces as Layer 3 EtherChannels, perform this task for each interface: 

Switch(config)# interface port-channel 

port_channel_number 

Creates the port-channel interface. The value for 
port_channel_number can range from 1 to 64

Switch(config-if)# ip address 

ip_address mask 

Assigns an IP address and subnet mask to the 
EtherChannel.

Switch(config-if)# end 

Exits configuration mode.

Switch# show running-config interface 

port_channel_number 

Verifies the configuration.

Switch(config)# interface {fastethernet | 

| tengigabitethernet} 

slot/port 

Selects a physical interface to configure.

Switch(config-if)# no switchport

Makes this a Layer 3 routed port.

Switch(config-if)# no ip address 

Ensures that there is no IP address assigned to the 
physical interface. 

Switch(config-if)# channel-group 

port_channel_number 

 {active | on | auto | passive | desirable} 

Configures the interface in a port-channel and specify 
the PAgP or LACP mode.

If you use PAgP, select the keywords auto and 
desirable.

If you use LACP, select the keywords active and 
passive.
