Channel-Protocol - Cisco Catalyst 3750-X Command Reference Manual

Chapter 2 Catalyst 3750-X and 3560-X Switch Cisco IOS Commands

channel-protocol

Use the channel-protocol interface configuration command on the switch stack or on a standalone
switch to restrict the protocol used on a port to manage channeling. Use the no form of this command to
return to the default setting.
Syntax Description
lacp
pagp
Defaults No protocol is assigned to the EtherChannel.
Command Modes Interface configuration
Command History Release
12.2(53)SE2
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.
