Cisco Systems 7600 manual Configuring Channel Groups, 12-8

Chapter 12 Configuring EtherChannels

Configuring EtherChannels

With Release 12.2(18)SXE and later releases, the group_number can be 1 through 256, up to a maximum of 128 port-channel interfaces. With releases earlier than Release 12.2(18)SXE, the group_number can be 1 through 256, up to a maximum of 64 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 Router#

Configuring Channel Groups

	Note	• 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 12-7), 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.
		To configure channel groups, perform this task for each LAN port:
	Command		Purpose
Step 1
	Router(config)# interface type1 slot/port		Selects a LAN port to configure.
Step 2
	Router(config-if)# no ip address		Ensures that there is no IP address assigned to the LAN
			port.
Step 3
	Router(config-if)#channel-protocol (lacp pagp}		(Optional) On the selected LAN port, restricts the
			channel-groupcommand to the EtherChannel protocol
			configured with the channel-protocolcommand.
	Router(config-if)# no channel-protocol		Removes the restriction.
