channel-group

Configures a physical interface to an EtherChannel.

Syntax

channel-group number mode on
no channel-group

Parameters

number
Number of the channel group. Valid range is from 1 to 255.
mode
Specifies the EtherChannel mode of the interface.
on
This is the default. Specifies that all EtherChannels that are not running LACP remain in this mode.

Modes

Interface config mode

Usage Guidelines

An EtherChannel in the on channel mode is a pure EtherChannel (static-lag) and can aggregate a maximum of 64 ports.

Only one port can be mapped with one channel-group.

This command requires that a group is already present.

MTU must not be configured.

The speed of member-ports should be same as that of the current port.

When the last physical interface is deleted from an EtherChannel, the EtherChannel is not removed. To remove the interface from the channel group, use the no interface port-channel command.

Message Reason
Error: Invalid configuration, port-channel 2 not present. Trying to configure the channel-group without creating the port-channel
Error: already mapped to port-channel 1. Trying to configure the channel-group which is already mapped to the port-channel
Error: MTU needs to be unconfigured before adding an interface to port-channel. Trying to add interfaces to the port-channel without removing MTU configuration
Error: speed configuration not allowed when interface is already member of a port-channel. Trying to configure speed when the interface is already a port-channel member

Examples

The following example configures the physical interface from the Ether Channel.

device# configure terminal
device(config)# interface ethernet 1/1
device(config-if-eth-1/1)# channel-group 1 mode on
device(config-if-eth-1/1)# no shutdown
device(config-if-eth-1/1)# end 

device# show running-configuration
interface ethernet 1/1
channel-group 1 mode on
no shutdown
