display cfm mp-info

Function

The display cfm mp-info command displays information about CFM objects on a specified interface or in a VLAN.

Format

display cfm mp-info [ interface interface-type interface-number ] [ level md-level ] [ inward | outward ] [ vlan vlanid | no-associated-vlan ]

Parameters

Parameter	Description	Value
interface-type interface-number	Displays CFM information on a specified interface. interface-type specifies the interface type. interface-number specifies the interface number.	-
level md-level	Specifies the level of an MD.	The value is an integer that ranges from 0 to 7. By default, the value is 0.
inward	Indicates the inward-facing MEP. An inward-facing MEP sends 802.1ag packets through all interfaces in a VLAN associated with an MA, except the interface on which the MEP is configured. That is, the inward-facing MEP broadcasts 802.1ag packets in the VLAN associated with the MA.	-
outward	Indicates the outward-facing MEP. An outward-facing MEP sends 802.1ag packets through an interface on which the MEP is configured.	-
vlan vlanid	Displays CFM information in a specified VLAN.	The value is an integer that ranges from 1 to 4094.
no-associated-vlan	Indicates the MP that is not associated with a VLAN.	-

Usage Guidelines

Usage Scenario

You can use the display cfm mp-info command to view information about CFM objects and the relationship between MPs on the interface so that you can configure MEPs correctly.

Prerequisites

CFM has been enabled globally using the cfm enable (system view) command.

Precautions

IEEE 802.1ag has two versions: IEEE 802.1ag Draft 7 and IEEE Standard 802.1ag-2007. This command can be used only on the device running IEEE Standard 802.1ag-2007.

Multiple MEPs can be configured and multiple MIPs can be generated on an interface; however, the levels of MEPs or MIPs must be the same. If the configuration is incorrect, CCM leak occurs or LBR or LTR messages cannot be sent correctly.

Example

# Display information about the specified interface, MD level, MEP type, and VLAN.

<HUAWEI> display cfm mp-info interface gigabitethernet 0/0/1

The total number of MPs is : 1              
The number of MEPs is : 1. The number of MIPs is : 0.

**Table 1** Description of the **display cfm mp-info** command output
Item	Description
Interface Name	Name of the interface.
MD Name	Name of the MD. To set the name of the MD, run the cfm md command.
MD Name Format	Format of the MD name: no-md-name dns mac-address string To set the format of the MD name, run the cfm md command.
Level	Level of the MD, MA, or MP. The value ranges from 0 to 7. A higher level indicates a higher priority. To set the MD level, run the cfm md command.
MA Name	Name of the MA. To set the name of the MA, run the ma command.
MEP ID	ID of the MEP. To set the ID of the MEP, run the mep mep-id command.
CCM Send	Whether the MEP is enabled to send CCMs: enabled disabled To set the parameter, run the mep ccm-send enable command.
Direction	Type of the MEP: inward outward To set the type of the MEP, run the mep mep-id command.
VLAN ID	ID of the VLAN associated with an MA. To set the ID of the VLAN associated with an MA, run the map command.
VSI Name	Name of the VSI associated with an MA.
L2VC ID	ID of the L2VC associated with an MA.
MAC Address	MAC address of the MEP or MIP. NOTE: An MP's MAC address can be a bridge MAC address or the MAC address of the interface where the MP is configured. The MAC address depends on the configured MP address model: If the shared MP address model is configured, an MP uses a bridge MAC address as its own MAC address. If the independent MP address model is configured, an MP uses the MAC address of the interface where the MP is configured.
MEP Pe-vid	VLAN ID in the outer tag of a VLAN frame.
MEP Ce-vid	VLAN ID in the inner tag of a VLAN frame.
MEP Vid	ID of a VLAN.
Alarm Status	Type of alarm: unexpectedMEGLevel: The MD level carried in a CCM sent by the RMEP was different from that specified on the MEP. unexpectedMEP: The trap about inconsistency between the MD level carried in a CCM sent by the RMEP and that specified on the MEP was cleared. mismerge: An MD or MA name carried in a CCM sent by the RMEP was different from that specified on the MEP. 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 time 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 RMEP sent a CCM carrying the RDI flag with the value of 1 to the MEP.
Alarm AIS	Whether the alarm reporting function of a specific alarm indication signal (AIS) is enabled: enable disable
Alarm RDI	Whether the alarm reporting function of a specific remote defect indication (RDI) is enabled: enable disable
