Configuring Channel Groups - Cisco 7604 Configuration Manual

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

•
To configure channel groups, perform this task for each LAN port:
Command
Step 1
Router(config)# interface type
Step 2
Router(config-if)# no ip address
Step 3
Router(config-if)# channel-protocol (lacp | pagp}
Router(config-if)# no channel-protocol

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.

Purpose
Selects a LAN port to configure.
Ensures that there is no IP address assigned to the LAN
port.
(Optional) On the selected LAN port, restricts the
channel-group command to the EtherChannel protocol
configured with the channel-protocol command.
Removes the restriction.
