To put a MEP out of LCK condition, enter the ethernet cfm lck stop mpid local-mpid domain
domain-name vlan vlan-id privileged EXEC command. To put an interface out of LCK condition, enter
the ethernet cfm lck start interface interface-id direction {inward | outward} privileged EXEC
command.
EXAMPLE
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
Step 18
ethernet cfm lck start mpid local-mpid
domain domain-name vlan vlan-id [drop
l2-bpdu]
(Optional) Put a MEP in LCK condition.
• The mpid local-mpid domain domain-name
vlan vlan-id identify the MEP.
• (Optional) drop l2-bpdu specifies that the
switch should drop all data frames, all Layer 3
control traffic, and all Layer 2 BPDUs except
CFM frames for that MEP. If not entered, the
switch drops only data frames and Layer 3
control frames.
Step 19
ethernet cfm lck start interface interface-id
direction {up | down} [drop l2-bpdu]
(Optional) Put an interface in LCK condition.
• 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-bpdu specifies 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 20
show ethernet cfm smep [interface
interface-id]
Verify the configuration.
Step 21
show ethernet cfm error Display received ETH-LCK frames.
Step 22
copy running-config startup-config (Optional) Save your entries in the configuration
file.
