loss-measure single-ended send

Function

The loss-measure single-ended send command enables on-demand single-ended packet loss measurement.

By default, on-demand single-ended packet loss measurement is disabled.

Format

loss-measure single-ended send test-id test-id interval { 1000 | 10000 } count count-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.
interval	Specifies the interval at which Loss Measurement Messages (LMMs) are sent.	The value is 1000 or 10000.
count count-value	Specifies the number of the single-ended frame loss measurement operations.	The value is an integer ranging from 1 to 60.

Usage Guidelines

Usage Scenario

On-demand OAM refers to OAM actions which are initiated via manual intervention for a limited time to carry out diagnostics. On-demand OAM can result in singular or periodic OAM actions during the diagnostics time interval. Single-ended LMMs can be used for packet loss measurement in on-demand OAM.

To implement singular or periodic packet loss measurement, you can run this command.

Prerequisites

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

Run the cfm version standard command in the system view to set the CFM version to IEEE Standard 802.1ag-2007.
CFM has been enabled globally using the cfm enable command in the system view.
Run the cfm md command in the system view to create an MD.
An MA is created through the ma command in the MD view.
Outward MEPs are supported in VLL, VPLS, and VLAN scenarios, and inward MEPs are supported in VPLS and VLL scenarios. Creates an MEP based on the MEP type.
Run the mep mep-id command with inward specified in the MA view to create an inward-facing MEP.
Run the mep mep-id command with outward specified in the MA view to create an outward-facing MEP.
Run the remote-mep command in the MA view to create an RMEP in the MA.
Run the mep ccm-send enable command in the MA view to enable the 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.
A test instance has been created using the test-id command in the MA view.

Configuration Impact

After the configuration is complete, on-demand single-ended frame loss measurement is implemented.

Precautions

Configuring on-demand single-ended frame loss measurement involves the setting of the remote MEP ID or destination MAC address, interval at which LMMs are sent, and measurement period.

If the local MEP has not learned the MAC address of the remote MEP, you must specify the destination MAC address for single-ended frame loss measurement.
If the local MEP has learned the MAC address of the remote MEP, you can specify the remote MEP ID for single-ended frame loss measurement.

Example

# Enable single-ended frame loss measurement and set the measurement interval to 10 seconds, measurement times to 60, and test instance to 1.
