Chapter 2 Cisco IOS Commands for the Catalyst 4500 Series Switches
channel-protocol
channel-proto col
To enable LACP or PAgP on an interface, use the chan nel-protocol command. To disable the p rotocols,
use the no form of this command.
channel-protocol {lacp | pagp}
no channel-protocol {lacp | pagp}
Syntax Description
Defaults pagp
Command Modes Interface configur ation mode
Usage Guidelines You can also select the protocol using the chan nel-group command.
If the interface belongs to a channel, the no form of this command is rejected.
All ports in an EtherChannel must use the same protocol; you cannot run two protocols on one module.
PAgP and LACP are not compatible; both ends of a channe l must use the same protoc ol.
You can manually configure a sw itch with PA gP on one s ide and LACP on t he other side in the on mode .
You can change the protocol at any time, but this change causes all existing Ethe rChannels to reset to
the default channel mode for the new protoc ol. You can use the channel-protocol command to restrict
anyone from selecting a mode that is not applicable to the selected protocol.
Configure all ports in an EtherChannel to operate at the same speed and duplex mode (full duplex only
for LACP mode).
For a complete list of guidelines, refer to the “Configuring EtherChannel” section of the Catalyst 4500
Series Switch Cisco IOS Software Con figuration Guide.
Examples This example shows how to select LACP to manage channeling on the interface:
Switch(config-if)# channel-protocol lacp
Switch(config-if)#
lacp Enables LACP to manage channeling.
pagp Enables PAgP to manage cha nneling.
