Chapter Cisco MWR 2941 Router Command Reference, Release 15.1(3)MR
ethernet cfm mep crosscheck
Usage Guidelines Before you issue this command, you must configure a static list of MEPs using the mep crosscheck
mpid vlan command. To enable cross-checking after a device has booted up, you must issue the ethernet
cfm mep crosscheck enable command.
A no form of this command does not exist. Cross-checking is disabled when you issue the command with
the disable keyword.
In CFM IEEE, if a domain name has more than 43 characters, a warning message is displayed notifying
that the maintenance domain ID (MDID) will be truncated to 43 characters in continuity check messages
(CCMs) if “id <fmt> <MDID>” is not configured.
To view the results of a cross-check operation, use the show ethernet cfm maintenance-points remote
crosscheck command. To view errors in the cross-check operation, use the show ethernet cfm errors
command. Both commands are used in privileged EXEC mode.
Traps are generated after a cross-check operation is completed if cross-check traps are already enabled
and, if as the result of the cross-check operation, a condition warrants a trap to be sent.
An EVC is an association of two or more user network interfaces (UNIs). EVCs are not supported in
Cisco IOS Release 12.2(33)SXI2.
Examples The following example shows how to enable an Ethernet CFM MEP cross-check on a port MEP in
CFM IEEE:
Router# ethernet cfm mep crosscheck enable domain customerA port
The following example shows how to enable an Ethernet CFM MEP cross-check in CFM D1 at level 2
for VLAN IDs in the range of 3000 to 3375:
