ethernet cfm mep crosscheck
To enable cross-checking between the list of configured remote maintenance endpoints (MEPs) of a domain and MEPs learned through continuity check messages (CCMs), use the ethernet cfm mep crosscheck command in privileged EXEC mode or global configuration mode. To disable cross-checking, use the ethernet cfm mep crosscheck disable command.

Syntax Description
enable |
Indicates that cross-checking will occur. |
disable |
Indicates that cross-checking will not occur. |
level level-id |
Indicates a maintenance level for configuration. Integer from 0 to 7 that identifies the maintenance level. |
, level-id - level-id |
(Optional) Integer values from 0 to 7. The comma must be entered to separate level ID ranges. The hyphen is required to separate starting and ending level ID values that are used to define each range of IDs. |
vlan vlan-id |
Indicates a VLAN for cross-checking. Integer from 1 to 4094 that identifies the VLAN. |
level-id - level-id |
Integer values from 0 to 7. The hyphen is required to separate starting and ending level ID values that are used to define the range of IDs. |
any |
|
evc evc-name |
String that associates an Ethernet virtual connection (EVC) to the service instance. Maximum: 100 bytes. |
domain domain-name |
Specifies the domain where the destination MEP resides. Maximum:154 characters. |
service |
Specifies the maintenance association (MA) within the domain. |
short-ma-name |
The short-name identifier for the MA service. The domain name and short MA name combined cannot exceed 48 bytes. |
icc icc-code meg-id |
ITU Carrier Code (ICC) (maximum: 6 characters) and unique maintenance entity group (MEG) ID Code (UMC) (maximum: 12 characters). |
number ma-number |
The MA number. Range: 0 to 65535. |
vlan-id vlan-id |
The primary VLAN ID. Range: 1 to 4094. |
vpn-id vpn-id |
The VPN ID. Range: 1 to 32767. |

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 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.
Examples
The following example shows how to enable an Ethernet CFM MEP cross-check on an MEP in CFM IEEE:
Device# ethernet cfm mep crosscheck enable domain customerA service zzz
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 from 3000 to 3375:
Device# ethernet cfm mep crosscheck enable level 2 vlan 3000-3375
