Parameters
service-instance instance-id: Specifies a service instance by its ID in the range of 1 to 32767.
mep mep-id: Specifies the source MEP by its ID in the range of 1 to 8191.
target-mac mac-address: Specifies the target MEP by its MAC address, which is in the format of H-H-H.
target-mep target-mep-id: Specifies the target MEP by its ID in the range of 1 to 8191.
dot1p dot1p-value: Specifies an 802.1p priority for DMM frames. The value range for the dot1p-value argument is 0 to 7. The default value is 7.
number number: Specifies the number of DMM frames to be sent. The value range for the number argument is 2 to 10, and the default is 5.
interval interval: Specifies the DMM frame sending interval, in seconds. The value takes 1, 10, 60, or 600. The default value is 1.
Usage guidelines
Short-period two-way DM sends a configurable number of DMM frames at a configuration interval. It measures the two-way frame delay between the source and target MEPs after receiving DMR frames.
Two types of two-way DM are available: short-period two-way DM and continual two-way DM. They cannot be configured at the same time for one source MEP. If you have configured continual two-way DM, you can configure short-period two-way DM only after you disable continual two-way DM. If you have configured short-period two-way DM, you can configure continual two-way DM only after the short-period two-way DM ends.
Examples
# Configure short-period DM to test the two-way frame delay between source MEP 1101 and target MEP 2001 in service instance 1.

Parameters
service-instance instance-id: Specifies a service instance by its ID in the range of 1 to 32767.
mep mep-id: Specifies the source MEP by its ID in the range of 1 to 8191.
target-mac mac-address: Specifies the target MEP by its MAC address, which is in the format of H-H-H. The MAC address cannot be a MAC address of a local MEP or a non-unicast MAC address.
target-mep target-mep-id: Specifies the target MEP by its ID in the range of 1 to 8191.
dot1p dot1p-value: Specifies the 802.1p priority of DMM frames to be sent. The value range for the dot1p-value argument is 0 to 7, and the default is 7. The larger the value, the higher the priority.
interval interval: Specifies the interval for sending DMM frames, in seconds. The value for the interval argument can be 1, 10, 60, or 600, and the default is 1.
Usage guidelines
Continual two-way DM continually sends DMM frames at a configurable interval. It measures the two-way frame delay between the source and target MEPs after receiving the returned DMR frames.
To modify continual two-way DM settings for a source MEP, disable continual two-way DM and then reconfigure the function for the source MEP.
Two types of two-way DM are available: short-period two-way DM and continual two-way DM. They cannot be configured at the same time for one source MEP. If you have configured continual two-way DM, you can configure short-period two-way DM only after you disable continual two-way DM. If you have configured short-period two-way DM, you can configure continual two-way DM only after the short-period two-way DM ends.
To display the continual two-way DM result, use the display cfd dm two-way history command on the device where the source MEP resides.
Inward-facing MEPs created in an Ethernet network do not support continual two-way DM.
Examples
# Configure continual two-way DM to test the two-way frame delay between source MEP 1101 and target MEP 2001 in service instance 1.
<Sysname> system-view
[Sysname] cfd dm two-way continual service-instance 1 mep 1101 target-mep 2001

Parameters
size size-value: Specifies the size of the buffer used to store the auto-detection result, in the range of 1 to 100 (in terms of auto-detection times). The default value is 5, which means the buffer stores the results of the recent five auto-detections.
Usage guidelines
This command enables the source MEP to send LTMs when it fails to receive CCMs from the target MEP within 3.5 times the sending interval. The destination of the LTMs is the target MEP, and the TTL field value is 255. Based on the returned LTRs, the fault source can be located on the faulty link.
If you disable automatic LTM sending, the content stored in the buffer will be removed.

Parameters
mep mep-id: Specifies the MEP ID, in the range of 1 to 8191.
service-instance instance-id: Specifies a service instance by its ID in the range of 1 to 32767.
inbound: Creates an inward-facing MEP.
Usage guidelines
In creating a MEP, the service instance you specified defines the MD and MA to which the MEP belongs.
You cannot create a MEP if the MEP ID is not included in the MEP list of the relevant service instance.
Configurations in Ethernet interface view take effect only on the current interface.
In an MPLS Layer 2 VPN:
· Only one inward-facing MEP can be configured for a CFD service instance.
· A MEP can only be configured on an AC interface to detect PW connectivity.
When configuring a MEP on a Layer 3 Ethernet subinterface, follow these restrictions and guidelines:
· To specify the VLAN ID, you must first configure the vlan-type dot1q vid vlan-id-list command and specify the same value for the vlan-id-list and vlan vlan-id parameters. For more information about the vlan-type dot1q vid vlan-id-list command, see VLAN termination commands in Layer 2—LAN Switching Command Reference.
· To specify the outer and inner VLAN IDs you must first configure the vlan-type dot1q vid second-dot1q command and set the same outer VLAN ID and the same inner VLAN ID in the two commands. For more information about the vlan-type dot1q vid second-dot1q command, see VLAN termination commands in Layer 2—LAN Switching Command Reference.

Parameters
meplist mep-list: Specifies a space-separated list of up to 10 MEP items. Each item specifies a MEP ID or a range of MEP IDs in the form of mep-id 1 to mep-id 2. The value range for the MEP ID is 1 to 8191. The mep-id 2 must be equal to or greater than mep-id 1.
service-instance instance-id: Specifies a service instance by its ID in the range of 1 to 32767.
Usage guidelines
A MEP list is a collection of local MEPs allowed to be configured and the remote MEPs to be monitored in the same MA.
Before creating a MEP list, create the relevant MD and service instance.
After you delete a MEP list, all local MEP configurations based on this list are deleted.

Parameters
service-instance instance-id: Specifies the service instance ID in the range of 1 to 32767.
ma-id: Creates an MA.
icc-based ma-name: Specifies that an MA is identified by an ICC. The ma-name argument is a string of 1 to 13 characters. An MD name must be compliant with the specifications in IEEE802.1ag-2007.
integer ma-num: Specifies that an MA is identified by an integer, where the ma-num argument is in the range of 0 to 65535.
string ma-name: Specifies that an MA is identified by a string, where the ma-name argument is string of 1 to 45 characters that can contain letters, numbers, and special characters such as grave accent (`), tilde (~), exclamation mark (!), at sign (@), number sign (#), dollar sign ($), percent (%), caret (^), ampersand (&), asterisk (*), brackets ({ }, ( ),[ ], < >), hyphen (-), underscore (_), plus (+), equal sign (=), vertical bar (|), colon (:), semicolon (;), quotation mark ('), comma (,), period (.), and slash (/).
vlan-based [ vlan-id ]: Specifies that an MA is identified by a VLAN ID, where the vlan-id argument is in the range of 1 to 4094. If you do not provide the vlan-id argument, the VLAN ID specified by vlan vlan-id is used. If the vlan vlan-id option is not provided, you must specify the vlan-id argument for the vlan-based [ vlan-id ] option.
ma-index index-value: Specifies an MA index in the range of 1 to 4294967295. If you do not specify this option, the system automatically assigns the smallest index number that is not in use. As a best practice, use the index automatically assigned by the system.
md md-name: Specifies the name of an MD. The md-name argument is a string of 1 to 43 characters that can contain letters, numbers, and special characters such as grave accent (`), tilde (~), exclamation mark (!), at sign (@), number sign (#), dollar sign ($), percent (%), caret (^), ampersand (&), asterisk (*), brackets ({ }, ( ),[ ], < >), hyphen (-), underscore (_), plus (+), equal sign (=), vertical bar (|), colon (:), semicolon (;), quotation mark (’), comma (,), period (.), and slash (/).
vlan vlan-id: Specifies the VLAN that the MA serves. The value range for the vlan-id argument is 1 to 4094.
xconnect-group group-name: Specifies the cross-connect group that the MA serves. The group-name argument is a case-sensitive string of 1 to 31 characters excluding hyphens (-).
connection connection-name: Specifies the cross-connect that the MA serves. The connection-name argument is a case-sensitive string of 1 to 20 characters excluding hyphens (-).
Usage guidelines
You must create the relevant MD before creating a service instance with the MD name.
Deleting a service instance also deletes the configurations related to that service instance.
Deleting a service instance not only removes the connection between the service instance and the relevant MA, but also deletes the MA.
When you create a service instance in an Ethernet network, follow these restrictions and guidelines:
· A service instance is indicated by an integer to represent an MA in an MD. An MA index uniquely identifies a specific MA in an MD. An MA index can be used in different MDs.
· With the vlan-based [ vlan-id ] or vlan vlan-id option, the command creates an MA carrying the VLAN attribute. If you do not specify the option, the command creates an MA carrying no VLAN attribute.
In an MPLS Layer 2 VPN, you must create the relevant cross-connect group and cross-connect or the relevant VSI before creating a service instance. For more information about cross-connect groups and cross-connects, see MPLS L2VPN in MPLS Configuration Guide.
The total number of characters of the ma-name and md-name arguments cannot exceed 45.

number number: Specifies the number of LMM frames to be sent. The value range for the number argument is 2 to 10, and the default is 5.
interval interval: Specifies the LMM frame sending interval, in seconds. The value takes 1, 10, 60, or 600. The default value is 1.
msec msec-interval: Specifies the LMM frame sending interval, in milliseconds. The value takes 100, 1000, 10000, 60000, or 600000. The default value is 1000.
Usage guidelines
Short-period LM sends a configurable number of LMM frames at a configuration interval. It measures the frame loss between the source and target MEPs after receiving LMR frames.
Before enabling short-period one-way LM in an MPLS Layer 2 VPN, you must configure the same frame counting mode on the source MEP and target MEP.
If the frame counting mode is dot1p-based, you must specify the dot1p dot1p-value option. If the frame counting mode is port-based, do not specify the dot1p dot1p-value option.
Two types of one-way LM are available: short-period one-way LM and continual one-way LM. They cannot be configured at the same time for one source MEP. If you have configured continual LM, you can configure short-period LM only after you disable continual LM. If you have configured short-period LM, you can configure continual LM only after the short-period LM ends.
Examples
# Configure short-period LM to measure the frame loss between source MEP 1101 and target MEP 2001 in service instance 1.
<Sysname> cfd slm service-instance 1 mep 1101 target-mep 2001

Usage guidelines
Continual LM continually sends LMM frames at a configurable interval. It measures the frame loss between the source and target MEPs after receiving LMR frames.
If the frame counting mode is dot1p-based, you must specify the dot1p dot1p-value option. If the frame counting mode is port-based, do not specify the dot1p dot1p-value option.
To modify continual LM settings for a source MEP, disable continual LM and then reconfigure the function for the source MEP.
Before enabling continual one-way LM in an MPLS Layer 2 VPN, you must configure the same frame counting mode on the source MEP and target MEP.
Two types of one-way LM are available: short-period one-way LM and continual one-way LM. They cannot be configured at the same time for one source MEP. If you have configured continual LM, you can configure short-period LM only after you disable continual LM. If you have configured short-period LM, you can configure continual LM only after the short-period LM ends.
To display the continual LM result, use the display cfd slm history command on the device where the source MEP resides.
Inward-facing MEPs created in an Ethernet network do not support continual one-way LM.
Examples
# Configure continual LM to measure the frame loss between source MEP 1101 and target MEP 2001 in service instance 1.
