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 bridge 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.

pw-id pw-id: Specifies a PW by its ID in the range of 1 to 4294967295.
dot1p dot1p-value: Specifies an 802.1p priority for CCM frames. The value range for the dot1p-value argument is 0 to 7. The default value is 7.
Usage guidelines
The two-way LM function measures the frame loss between the source and target MEPs by using CCMs. The source MEP calculates the number of lost frames according to the counter values of two consecutive CCMs received (the current CCM and the previous CCM).
To view the bridge MAC address of the target MEP, execute the display lacp system-id command on the target MEP.
For the two-way LM function to take effect, you must configure it on both the local and peer devices.
If the device supports hardware CC, you can specify the target MEP only by its MAC address. You cannot specify the target MEP by its ID.
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 two-way LM settings for a source MEP, disable two-way LM and then reconfigure the function for the source MEP.
The two-way LM detection interval is the CCM interval. Before configuring two-way LM, configure the CCM interval field value to be greater than 2.
One-way LM and two-way LM cannot be configured at the same time for one source MEP. If you have configured short-period one-way LM or continual one-way LM, you can configure two-way LM only after you disable continual one-way LM or short-period one-way LM ends. If you have configured two-way LM, you can configure short-period one-way LM or continual one-way LM only after disable two-way LM.
To display the two-way LM result, use the display cfd dlm history command on the device where the source MEP or target MEP resides.
Examples
# Enable the continual two-way LM function to measure the frame loss between source MEP 1101 and target MEP 2001 in service instance 1.
<Sysname> system-view
[Sysname] cfd dlm continual service-instance 1 mep 1101 target-mep 2001

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.
You can implement two-way DM by using the following test types:
· Continual two-way DM.
· Short-period two-way DM.
· Scheduled two-way DM.
You can configure only one of the test types for a source MEP. To change the test type, you must stop the ongoing test and then start a new test.
To view the bridge MAC address of the target MEP, execute the display lacp system-id command on the target MEP.
If the device supports hardware CC, you can only specify the target MEP by its MAC address. You cannot specify the target MEP by its ID.
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.
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.

Parameters
dot1p-based: Counts packets by 802.1p priority.
port-based: Counts packets by interface.
Usage guidelines
To obtain accurate test results, 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 when configuring the cfd slm, cfd slm continual, and cfd dlm continual commands. If the frame counting mode is port-based, do not specify the dot1p dot1p-value option when configuring the cfd slm, cfd slm continual, and cfd dlm continual commands.
If LM has been configured for a MEP, the frame counting mode on the interface where the MEP resides cannot be modified.
This command can be configured only in MPLS Layer 2 VPNs.

Usage guidelines
The short-period one-way LM function measures the frame loss between the source and target MEPs by using LMM frames and LMR frames.
You can implement one-way LM by using the following test types:
· Continual one-way LM.
· Short-period one-way LM.
· Scheduled one-way LM.
You can configure only one of the test types for a source MEP. To change the test type, you must stop the ongoing test and then start a new test.
To view the bridge MAC address of the target MEP, execute the display lacp system-id command on the target MEP.
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.
Short-period one-way LM and continual two-way LM cannot be configured at the same time for one source MEP. If you have configured short-period one-way LM, you can configure continual two-way LM only after the short-period one-way LM ends. If you have configured continual two-way LM, you can configure short-period one-way LM only after you disable continual two-way LM.
Examples
# Enable the short-period one-way LM function to measure the frame loss between source MEP 1101 and target MEP 2001 in service instance 1.

number number: Specifies the number of SLM frames to be sent at a time. The value range for the number argument is 1 to 100, and the default is 10. After the number of SLM frames are sent, a frame loss measurement is performed.
Usage guidelines
The continual single-ended synthetic LM function measures the frame loss between the source and target MEPs by using SLM frames and SLR frames.
You can implement single-ended synthetic LM by using the following test types:
· Continual single-ended synthetic LM.
· Short-period single-ended synthetic LM.
· Scheduled single-ended synthetic LM.
You can configure only one of the test types for a source MEP. To change the test type, you must stop the ongoing test and then start a new test.
To view the bridge MAC address of the target MEP, execute the display lacp system-id command on the target MEP.
This function is supported only in EVPN VPWS and MPLS VPWS networks.
To display the continual single-ended synthetic LM result, use the display cfd synthetic-slm history command on the device where the source MEP resides.
Examples
# Enable the continual single-ended synthetic LM function to measure the frame loss between source MEP 1101 and target MEP 2001 in service instance 1.
