channel-protocol

Use the channel-protocol interface configuration command to restrict the protocol used on a port to
manage channeling. Use the no form of this command to return to the default setting.

Command Modes Interface configuration
Command History Release

Usage Guidelines Use the channel-protocol command only to restrict a channel to LACP or PAgP. If you set the protocol
by using the channel-protocol command, the setting is not overridden by the channel-group interface
configuration command.
You must use the channel-group interface configuration command to configure the EtherChannel
parameters. The channel-group command also can set the mode for the EtherChannel.
You cannot enable both the PAgP and LACP modes on an EtherChannel group.
PAgP and LACP are not compatible; both ends of a channel must use the same protocol.
Examples
This example shows how to specify LACP as the protocol that manages the EtherChannel:
Switch(config-if)# channel-protocol lacp
You can verify your settings by entering the show etherchannel [channel-group-number] protocol
privileged EXEC command.
