loss-measure enable mid-point

Function

The loss-measure enable mid-point command enables packet loss measurement on a mid-point.

The undo loss-measure enable mid-point command disables packet loss measurement on a mid-point.

By default, packet loss measurement is disabled on a mid-point from an IP Flow Performance Measurement (IP FPM) instance.

Format

loss-measure enable mid-point [ time-range time-range | continual ]

loss-measure enable mid-point [ time-range time-range ]

undo loss-measure enable mid-point [ continual ]

Parameters

Parameter	Description	Value
time-range time-range	Specifies a time range from packet loss measurement on a mid-point.	The value is an integer that can be 5, 10, 15, or 30, in minutes. The default value is 10 minutes.
continual	Indicates proactive delay measurement.	-

Usage Guidelines

Usage Scenario

The IP FPM performance statistics serve as a reliable reference for assessing IP network performance and therefore are useful for fault diagnosis and service statistics. To diagnose network faults and locate faulty nodes when network performance deteriorates, run the loss-measure enable mid-point command.

Prerequisites

An IP FPM model has been established, including configuring a DCP and MCP, binding a TLP to a physical interface, and creating a target flow and IP FPM instance.

Precautions

If a master/slave switchover is performed, or the device is restarted, packet loss measurement on a mid-point will become invalid. You must reconfigure the function.

Example

# Enable packet loss measurement on a mid-point in an IP FPM instance, the time range from packet loss measurement on a mid-point is 30 m.
