	Command	Purpose
Step 18
	ethernet cfm lck start interface interface-id	(Optional) Apply the LCK condition to an interface.
	direction {up down} [drop l2-bpdu]	• interface interface-id—Specify the interface to be put
		in LCK condition.
		• direction inward—The LCK is in the direction toward
		the relay; that is, within the switch.
		• direction outward—The LCK is in the direction of
		the wire.
		• (Optional) drop l2-bpduspecifies that all Layer 2
		BPDUs except CFM frames, all data frames, and all
		Layer 3 control traffic are dropped for that MEP. If not
		entered, only data frames and Layer 3 control frames
		are dropped.
Step 19
	show ethernet cfm smep [interface interface-id]	Verify the configuration.
Step 20
	show ethernet cfm error	Display received ETH-LCK frames.
Step 21
	copy running-config startup-config	(Optional) Save your entries in the configuration file.

To remove the LCK condition from MEP, enter the ethernet cfm lck stop mpid local-mpiddomain domain-namevlan vlan-idprivileged EXEC command. To put an interface out of LCK condition, enter the ethernet cfm lck start interface interface-iddirection {inward outward} privileged EXEC command.

This is an example of the output from the show ethernet cfm smep command when ethernet LCK has been enabled:

Switch# show ethernet cfm smep SMEP Settings:

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

Interface: GigabitEthernet0/3

LCK-Status: Enabled

LCK Period: 60000 (ms)

Level to transmit LCK: Default

AIS-Status: Enabled

AIS Period: 60000 (ms)

Level to transmit AIS: Default

Defect Condition: AIS

Managing and Displaying Ethernet CFM Information

Use the following commands in the privileged EXEC mode to clear Ethernet CFM information.

Table 1		Clearing CFM Information
	Command		Purpose
	clear ethernet cfm ais domain domain-name		Clear MEPs with matching domain and VLAN ID out of AIS defect
	mpid id {vlan vlan-id port}		condition.
	clear ethernet cfm ais link-status interface		Clear a SMEP out of AIS defect condition.
	interface-id
	clear ethernet cfm error		Clear all CFM error conditions, including AIS.
