loss-measure single-ended send

Function

The loss-measure single-ended send command enables single-ended frame loss measurement.

By default, single-ended frame loss measurement is disabled.

Only the S5730-HI, S5731-H, S5731-S, S5731S-H, S5731S-S, S5732-H, S6720-HI, S6730-H, S6730S-H, S6730-S, and S6730S-S support this command.

Format

loss-measure single-ended send mep mep-id [ mac mac-address | remote-mep mep-id ] interval { 1000 | 10000 } count count-value

Parameters

Parameter	Description	Value
mep mep-id	Specifies the ID of a MEP.	The value is an integer in the range from 1 to 8191.
mac mac-address	Specifies the MAC address of an RMEP.	The value is in the format of H-H-H, where H is a hexadecimal number of 1 to 4 digits.
remote-mep mep-id	Specifies the ID of an RMEP.	The value is an integer in the range from 1 to 8191.
interval	Specifies the interval at which LMMs are sent.	The value is 1000 or 10000, in milliseconds.
count count-value	Specifies the single-ended frame loss measurement count.	The value is an integer in the range from 1 to 60.

Usage Guidelines

When the packet loss rate is detected on a link to evaluate the link performance, you can run this command to enable the remote device to receive LMMs.

Single-ended frame loss measurement is implemented for the link between the local MEP and an RMEP identified by an ID or a MAC address.

If the local MEP has not learned the MAC address of the RMEP, the MAC address of the RMEP must be specified to implement single-ended frame loss measurement.
If the local MEP has learned the MAC address of the RMEP, the ID of the RMEP can be used to implement single-ended frame loss measurement.

Prerequisites

The command takes effect only after the following configurations are completed:

Run the cfm version standard command in the system view to specify IEEE Standard 802.1ag-2007 for CFM.
Run the cfm enable (system view) command to enable CFM globally.
Run the cfm md command in the system view to create an MD.
Run the ma command in the MD view to create an MA.
Run the mep mep-id command in the MA view to create an inward-facing MEP.

If remote-mep mep-id is specified in the delay-measure one-way continual command, the following configurations must be completed:

Run the remote-mep command in the MA view to create an RMEP.
Run the mep ccm-send enable command in the MA view to enable the local MEP in the MA to send CCMs.
Run the remote-mep ccm-receive enable command in the MA view to enable the MEP to receive CCMs from the RMEP in the same MA.

Example

# In the VLAN scenario, enable single-ended frame loss measurement and set the RMEP ID to 2, measurement interval to 10 seconds, and measurement count to 60 times.
