Configuring Channel Groups - Cisco WS-SUP32-GE-3B - Supervisor Engine 32 Software Configuration Manual

Chapter 10 Configuring EtherChannels
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 group_number
The group_number can be 1 through 256, up to a maximum of 128 port-channel interfaces. 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 3 EtherChannels, you must manually create the port channel logical
interface first (see the "Configuring Port Channel Logical Interfaces for Layer 3 EtherChannels"
section on page 10-6), and then put the Layer 3 LAN ports into the channel group as described in
this section.
When configuring Layer 2 EtherChannels, configure the LAN ports with the channel-group
command as described in this section, which automatically creates the port channel logical interface.
You cannot put Layer 2 LAN ports into a manually created port channel interface.
For Cisco IOS to create port channel interfaces for Layer 2 EtherChannels, the Layer 2 LAN ports
must be connected and functioning.
