Configuring Layer 3 Etherchannels; Creating Port-Channel Logical Interfaces - Cisco ME 3400 Software Configuration Manual

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:
Switch# configure terminal
Switch(config)# interface range fastethernet0/1 -2
Switch(config-if-range)# port-type nni
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
This example shows how to configure an EtherChannel. It assigns two ports as static-access ports in
VLAN 10 to channel 5 with the LACP mode active:
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 active
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.
The switch must be running the metro IP access image to support Layer 3 ports.
Note

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.
To move an IP address from a physical port to an EtherChannel, you must delete the IP address from the
Note
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.
Command
Step 1
configure terminal
Step 2 interface port-channel port-channel-number
Step 3 no switchport
Step 4 ip address ip-address mask

Purpose
Enter global configuration mode.
Specify the port-channel logical interface, and enter interface
configuration mode.
For port-channel-number, the range is 1 to 48.
Put the port-channel interface into Layer 3 mode.
Assign an IP address and subnet mask to the EtherChannel.
Return to privileged EXEC mode.
Verify your entries.
