Managing and Displaying Ethernet CFM Information
This is an example of the output from the show ethernet cfm smep command when Ethernet AIS has
been enabled:
Router# show ethernet cfm smep
SMEP Settings:
--------------
Interface: GigabitEthernet1/0/3
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
Using Multicast Ethernet Loopback
You can use the ping privileged EXEC command to verify bidirectional connectivity of a MEP, as in
this example:
Router# ping ethernet multicast domain CD vlan 10
Type escape sequence to abort.
Sending 5 Ethernet CFM loopback messages to 0180.c200.0037, timeout is 5 seconds:
Reply to Multicast request via interface FastEthernet1/0/3, from 001a.a17e.f880, 8 ms
Total Loopback Responses received: 1

mpid id {vlan vlan-id | port}
Clear MEPs with matching domain and VLAN ID out of AIS defect
condition.
clear ethernet cfm ais link-status interface
interface-id
Clear a SMEP out of AIS defect condition.
clear ethernet cfm error Clear all CFM error conditions, including AIS.
Table 15-2 Displaying CFM Information
Command Purpose
show ethernet cfm domain [brief] Displays CFM domain information or brief domain information.
show ethernet cfm errors [configuration |
domain-id]
Displays CFM continuity check error conditions logged on a device since
it was last reset or the log was last cleared. When CFM crosscheck is
enabled, displays the results of the CFM crosscheck operation.
show ethernet cfm maintenance-points local
[detail | domain | interface | level | mep | mip]
Displays maintenance points configured on a device.
