delay-measure two-way send

Function

The delay-measure two-way send command configures on-demand two-way frame delay measurement.

By default, on-demand two-way frame delay measurement is not configured in an MA.

Format

delay-measure two-way send test-id test-id-value interval { 1000 | 10000 } count count-value

Parameters

Parameter	Description	Value
interval	Specifies the interval at which DMMs are sent.	Either 1000 or 10000 milliseconds
count count-value	Specifies the number of sent DMMs.	The value is an integer ranging from 1 to 60
test-id test-id-value	Specifies the ID of a test instance.	The value is an integer ranging from 1 to 4294967295.

Usage Guidelines

Usage Scenario

When the clocks of the MEPs at both ends of a link cannot be synchronized, you can run this command to implement singular or periodic on-demand two-way frame delay measurement.

Prerequisites

The delay-measure two-way command takes effect only after the following configurations are complete:

The CFM function is enabled globally by using the cfm enable command in the system view.
An MD is created by using the cfm md command in the system view.
An MA is created by using the ma command in the MD view.
Configure inward in the mep mep-id command to create an inward-facing MEP in an MA.
A remote MEP in the MA is created by using the remote-mep command in the MA view.
The local MEP in the MA is enabled to send CCMs by using the mep ccm-send enable command in the MA view.
The local MEP is enabled to receive CCMs from the remote MEP in the same MA by using the remote-mep ccm-receive enable command in the MA view.
A test instance is created by using the test-id command in the MA view.

Configuration Impact

After the configuration is complete, on-demand two-way frame delay measurement is implemented for links.

Precautions

To implement on-demand two-way frame delay measurement, you need to specify the RMEP ID or the destination MAC address, the interval at which DMMs are sent, and the measurement period.

If the local MEP has not learned the MAC address of the remote MEP, you must specify the destination MAC address for two-way frame delay measurement.
If the local MEP has learned the MAC address of the remote MEP, you can specify the remote MEP ID for two-way frame delay measurement.

Example

# Configure two-way frame delay measurement with the test instance ID of 1, DMM transmission interval of 10s, and measurement times of 60.
