loss-measure ratio-threshold

Function

The loss-measure ratio-threshold command configures the alarm and clear alarm thresholds of the packet loss ratio for a measurement instance on the MCP.

The undo loss-measure ratio-threshold command restores the default setting.

By default, the alarm and clear alarm thresholds of the packet loss ratio are not configured for a measurement instance on the MCP. That is, no alarm is generated for packet loss.

Format

loss-measure ratio-threshold upper-limit upper-limit lower-limit lower-limit

undo loss-measure ratio-threshold

Parameters

Parameter	Description	Value
upper-limit upper-limit	Specifies the alarm threshold for the packet loss ratio.	The value is a string of 1 to 10 digits and in the range of 0.000001 to 100. The value is accurate to six decimal places, in percentage.
lower-limit lower-limit	Specifies the clear alarm threshold for the packet loss ratio.	The value is a string of 1 to 10 digits and in the range of 0.000001 to 100. The value is accurate to six decimal places, in percentage. lower-limit must be smaller than or equal to upper-limit.

Usage Guidelines

Usage Scenario

After the alarm and clear alarm thresholds of the packet loss ratio are configured for a measurement instance on the MCP:

If the packet loss ratio in five consecutive measurement intervals exceeds the alarm threshold, the MCP reports the hwIpfpmLossRatioExceed alarm to the NMS to notify the link fault in real time.
If the packet loss ratio in five consecutive measurement intervals falls below the clear alarm threshold, the MCP reports the hwIpfpmLossRatioRecovery alarm to the NMS to notify link recovery in real time.

To facilitate operation and maintenance, you are advised to run this command to configure the alarm and clear alarm thresholds of the packet loss ratio for a measurement instance on the MCP according to network performance.

Precautions

If you run the loss-measure ratio-threshold command multiple times, only the latest configuration takes effect.

This command only configures the alarm and clear alarm thresholds of the packet loss ratio for a measurement instance on the MCP. The hwIpfpmLossRatioExceed and hwIpfpmLossRatioRecovery alarms are triggered only when the alarm and clear alarm functions are enabled and the packet loss ratio in five consecutive measurement intervals reaches the threshold.

Example

# Set the alarm and clear alarm thresholds of the packet loss ratio to 10% and 5.5% for measurement instance 1.
