Chapter 2 Catalyst 3560 Switch Cisco IOS Commands channel-protocol 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. channel-protocol {lacp | pagp} no channel-protocol Syntax Description lacp pagp Configure an EtherChannel with the Link Aggregation Control Protocol (LACP). Configure an EtherChannel with the Port Aggregation Protocol (PAgP). Defaults No protocol is assigned to the EtherChannel. Command Modes Interface configuration Command History Release 12.1(19)EA1 Modification This command was introduced. 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.
