display cfm mp-info

Function

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

Format

display cfm mp-info [ interface { interface-name | interface-type interface-number } ] [ level md-level ] [ inward | outward ] [ vlan vlanid | vsi vsi-name | no-associated-vlan | mpls l2vc [ peer-ip-value ] l2vc-id { raw | tagged } ]

Parameters

Parameter	Description	Value
interface interface-type interface-number	Specifies the type and number of an interface. The interface type can be Ethernet, Eth-Trunk, or GE.	-
level md-level	Specifies the level of an MD.	The value is an integer ranging from 0 to 7. The default value is 0.
inward	Indicates an inward-facing MEP that sends 802.1ag packets through all interfaces (except the interface on which the MEP resides) in the VLAN associated with the MA. That is, an inward-facing MEP broadcasts 802.1ag packets in the VLAN associated with the MA.	-
outward	Indicates an outward-facing MEP that sends 802.1ag packets through the interface on which the MEP resides.	-
vlan vlanid	Specifies the ID of a VLAN.	The value is an integer ranging from 1 to 4094.
vsi vsi-name	Specifies the name of a VSI.	The value is a string of 1 to 31 case-sensitive characters, spaces not supported. When double quotation marks are used around the string, spaces are allowed in the string.
no-associated-vlan	Indicates an MP that is not associated with a specified VLAN.	-
mpls	Displays CFM information in a specified Multiprotocol Label Switching Layer 2 Virtual Circuit (MPLS L2VC).	-
l2vc l2vc-id	Displays CFM information in a specified Multiprotocol Label Switching Layer 2 Virtual Circuit (MPLS L2VC).	The value is an integer ranging from 1 to 4294967295.
peer-ip-value	Specifies the IP address.	The value is in dotted decimal notation.
raw	Indicates the raw Virtual Leased Line (VLL) packet encapsulation that enables a device to remove VLAN tags from packets.	-
tagged	Indicates the tagged VLL packet encapsulation that enables a device to add VLAN tags to packets.	-

Usage Guidelines

Usage Scenario

Multiple MEPs can be configured on an interface, and multiple MIPs can be generated. However, the levels of the MEPs or MIPs must be the same. If MEPs are incorrectly configured, a CCM leak occurs or LBR or LTR messages cannot be correctly sent. You can run the display cfm mp-info command to view information about the CFM objects on an interface to obtain the relationship between MPs on the interface, which helps you configure MEPs correctly.

Prerequisites

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

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 mp-info** command output
Item	Description
The total number of MPs is	the total number of MPs.
The number of MIPs is	The number of MIP.
The number of MEPs is	The number of MEP.
MD Name	Name of the MD.
MD Name Format	Format of the MD name: no-md-name. dns. mac-address. string.
Level	Level of the MD, MA, or MP. The value ranges from 0 to 7. A larger level indicates a higher priority.
MA Name	the name of ma.
MEP ID	ID of the MEP.
MEP Pe-vid	Outer tag of the VLAN frame.
MEP Ce-vid	Inner tag of the VLAN frame.
MEP Vid	VLAN ID of the VLAN frame.
VLAN ID	ID of the VLAN associated with the MA.
VSI Name	Name of the VSI associated with the MA.
L2VC ID	ID of the L2VC associated with the MA.
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.
L2TPV3 Tunnel Name	Name of the L2TPv3 tunnel.
L2TPV3 Local Connection Name	Name of the L2TPv3 local connection.
Interface Name	Name of the interface.
CCM Send	Whether the function of sending CCMs is enabled: enabled. disabled.
Direction	Type of the MEP: inward. outward.
MAC Address	MAC address of the MP. An MP's MAC address can be a bridge MAC address or the MAC address of the interface on which the MP resides, depending on the configured MP MAC address model: If the shared MAC address model is configured, an MP uses a bridge MAC address as its own MAC address. If the individual MAC address model is configured, an MP uses the MAC address of the interface on which the MP resides.
