loss-measure single-ended-synthetic send interval

Function

The loss-measure single-ended-synthetic send interval command enables single-ended on-demand synthetic loss measurement (SLM).

By default, this function is disabled.

Format

loss-measure single-ended-synthetic send test-id test-id interval { 100 | 1000 } [ sending-count count-value ] [ time-out time-out-value ]

Parameters

Parameter	Description	Value
test-id test-id	Specifies the ID of a test instance.	The value is an integer ranging from 1 to 4294967295.
100	Specifies the interval.	-
1000	Specifies the interval.	-
sending-count count-value	Specifies the times that SLMs are sent within each measurement period.	The value is an integer ranging from 1 to 1000. The default value is 10.
time-out time-out-value	Specifies the timeout period during which the device waits for a reply.	The value is an integer ranging from 1 to 10, in seconds. The default value is 5s.

Usage Guidelines

Usage Scenario

When implementing frame loss measurement (LM), Maintenance Association End Points (MEPs) exchange ETH-LM frames. However, single-ended frame LM cannot collect accurate frame loss statistics on a point-to-multipoint or multipoint-to-multipoint network. To resolve this issue, configure single-ended on-demand SLM.

Prerequisites

Ensure that the following commands have been run:

IEEE Standard 802.1ag-2007 of Connectivity Fault Management (CFM) has been specified using the cfm version standard command in the system view.
The CFM function has been enabled globally using the cfm enable (system view) command in the system view.
A Maintenance Domain (MD) has been created using the cfm md command in the system view.
A Maintenance Association (MA) has been created using the ma command in the MD view.
An inward-facing MEP has been created using the mep mep-id command.
A test instance has been created using the test-id command.
A Remote Maintenance Association End Point (RMEP) has been created using the remote-mep command in the MA view.
The local MEP has been enabled to send CCMs to the RMEP in the MA using the mep ccm-send enable command in the MA view.
The local MEP has been enabled to receive Continuity Check Message (CCM) from the remote MEP in the same MA using the remote-mep ccm-receive enable command in the MA view.

Example

# Configure single-ended SLM with the test ID of 1, SLM frame transmission interval of 1s, SLM frame transmission times of 10, and timeout period waiting for a reply of 5s in VLL networking.
