threshold

Function

The threshold command sets thresholds for the round-trip delay and one-way transmission delay.

The undo threshold command deletes the thresholds.

By default, no threshold is configured.

Parameters

Parameter	Description	Value
owd-sd thresholdOwdSD	Specifies the threshold for a one-way (from the source to the destination) delay.	It is an integer ranging from 1 to 60000. The unit is determined by the timestamp unit configured using the timestamp-unit command.
rtd thresholdRtd	Specifies the threshold for a round-trip delay.	The value is an integer ranging from 1 to 60000. The unit is determined by the timestamp unit configured using the timestamp-unit command.
jitter-ds thresholdJitDS	Specifies the threshold for a one-way transmission (from the destination to the source) jitter.	The value is an integer ranging from 1 to 60000. The unit is determined by the timestamp unit configured using the timestamp-unit command.
jitter-sd thresholdJitSD	Specifies the threshold for a one-way (from the source to the destination) jitter.	The value is an integer ranging from 1 to 60000. The unit is determined by the timestamp unit configured using the timestamp-unit command.
owd-ds thresholdOwdDS	Specifies the threshold for a one-way transmission (from the destination to the source) delay.	The value is an integer ranging from 1 to 60000. The unit is determined by the timestamp unit configured using the timestamp-unit command.

Usage Guidelines

Usage Scenario

To set delay thresholds after NQA is configured, run the threshold command.

The conditions for alarm generation are as follows:

If the one-way delay from the destination to the source exceeds the parameter thresholdOwdDS, the nqaJitterStatsOWDThresholdNotificationDS alarm is generated.
If the one-way delay from the destination to the source is less than the parameter thresholdOwdDS, the one-way delay is within an allowable range, and no alarm is generated.
If the one-way delay from the source to the destination exceeds the parameter thresholdOwdSD, the nqaJitterStatsOWDThresholdNotificationSD alarm is generated.
If the one-way delay from the source to the destination is less than the parameter thresholdOwdSD, the one-way delay is within an allowable range, and no alarm is generated.
If the round-trip delay exceeds the parameter thresholdRtd, the nqaJitterStatsRTDThresholdNotification alarm is generated.
If the round-trip delay is less than the parameter thresholdRtd, the round-trip delay is within an allowable range, and no alarm is generated.

Prerequisites

Before using the send-trap command, run the test-type command to specify a test type.

Precautions

If parameters need to be changed during the running of the test instance, the system prompts you whether to terminate the test instance. Press "Y" or "N" as required.

If you press "Y", the test instance is terminated and parameters changed. The settings take effect after being committed. To restart the test instance, run the start command.
If you press "N", the test instance keeps running, and the parameters fail to be modified.
