Configuring EtherChannels

Router# show interfaces fastethernet 5/6 etherchannel

Port state	= Down Not-in-Bndl
Channel group	= 12		Mode =	Desirable-Sl	Gcchange = 0
Port-channel	=	null	GC =	0x00000000	Pseudo port-channel = Po1
2
Port index	=	0	Load =	0x00	Protocol = PAgP

Flags: S - Device is sending Slow hello. A - Device is in Auto mode.

d - PAgP is down.

Timers: H - Hello timer is running.

S - Switching timer is running.

Local information:

C - Device is in Consistent state. P - Device learns on physical port.

Q - Quit timer is running.

I - Interface timer is running.

			Hello	Partner	PAgP	Learning	Group

Age of the port in the current state: 04d:18h:57m:19s

This example shows how to verify the configuration of port channel interface 2 after the LAN ports have been configured:

Router# show etherchannel 12 port-channel

Port-channels in the group:

----------------------

Port-channel: Po12

------------

Age of the Port-channel		= 04d:18h:58m:50s
Logical slot/port	= 14/1		Number of ports = 0
GC	= 0x00000000		HotStandBy port = null
Port state	= Port-channel Ag-Not-Inuse

Configuring the LACP System Priority and System ID

The LACP system ID is the combination of the LACP system priority value and the MAC address of the router.

To configure the LACP system priority and system ID, perform this task:

	Command	Purpose
Step 1
	Router(config)# lacp system-priority	(Optional for LACP) Valid values are 1 through 65535.
	priority_value	Higher numbers have lower priority. The default is 32768.
	Router(config)# no lacp system-priority	Reverts to the default.
Step 2
	Router(config)# end	Exits configuration mode.
Step 3
	Router# show lacp sys-id	Verifies the configuration.

This example shows how to configure the LACP system priority:

Router# configure terminal

Router(config)# lacp system-priority 23456

Router(config)# end
