Usage Guidelines

Usage Scenario

After an RMEP is configured, you can run the display cfm remote-mep command to check the configurations on the RMEP.

Example

The actual command output varies according to the device. The command output here is only an example.

**Table 1** Description of the **display cfm remote-mep** command output
Item	Description
The total number of RMEPs is	Number of RMEPs.
The status of RMEPS	the remote meps status.
MD Name	Name of the MD.
Level	Level of the MD. The level ranges from 0 to 7. A larger level indicates a higher priority.
MA Name	Name of the MA.
RMEP ID	ID of the RMEP.
Vlan ID	ID of the VLAN associated with the MA.
VSI Name	Name of the virtual switching instance (VSI) associated with the MA.
L2VC ID	ID of the Layer 2 virtual circuit (L2VC).
L2VPN Name	Name of the L2VPN associated with the MA.
CE ID	ID of the local CE associated with the MA.
CE Offset	ID of the remote CE associated with the MA.
MAC	MAC address of the RMEP.
CCM Receive	Whether the device is enabled to receive continuity check messages (CCMs) from the RMEP: disabled: indicates that the device is disabled from receiving CCMs from the RMEP. enabled: indicates that the device is enabled to receive CCMs from the RMEP.
Trigger-If-Down	Whether Ethernet CFM is associated with an interface: disabled: indicates that the restart function is disabled on the interface with an RMEP. enabled: indicates that the restart function is enabled on the interface with an RMEP. That is, when a MEP detects a connectivity fault between the MEP and the RMEP in the same MA, the system blocks the interface on which the MEP is configured and then unblocks it.
CFM Status	Running status of CFM: up: The CC link is running properly. down: No MEP is configured on the device or the interface on which the configured MEP resides is invalid. The reason why the interface is invalid is as follows: The interface board or subcard is not installed or has been restarted. The Eth-Trunk has no member interface or all member interfaces are Down. disable: No CFM is configured. That is, neither the local CC link is configured to send CCMs nor the remote CC link is configured to receive CCMs.
CFM Status	the status of CFM.
Alarm Status	Alarm status of CFM: unexpectedPeriod: The CCM interval carried in a CCM sent by the RMEP was different from that specified on the MEP. unexpectedMAC: The source MAC address carried in a CCM sent by the RMEP was different from the RMEP's MAC address specified on the MEP. LOC: The MEP received no CCM in a period of 3.5 times the interval at which CCMs were sent. exceptionalMACstatus: TLV information carried in a CCM sent by the RMEP within a specified interval showed that the interface connecting the RMEP to the MEP became abnormal. RDI: The MEP received a CCM with the remote defect indication (RDI) flag. none: No alarm was generated. If only an RMEP is configured on a device, the CFM status is Down. The status cannot trigger an alarm, and the field value is none.
