NQA/4/NQA_JITTER_JITTER_THRESHOLD_SD

Message

NQA/4/NQA_JITTER_JITTER_THRESHOLD_SD: The JITTER-SD of the NQA entry exceeded the configured threshold. (OwnerIndex=[OwnerIndex], TestName=[TestName], TargetAddressType=[TargetAddressType], TargetAddress=[TargetAddress], Threshold=[Threshold], Index=[Index], RttMax=[RttMax], MaxDelaySD=[MaxDelaySD], MaxDelayDS=[MaxDelayDS], JITTEROverThresholdsSD=[JITTEROverThresholdsSD])

Description

Indicates that the jitter of a test exceeded the set threshold. The threshold could be set by the user. The threshold jitter-sd command could modify the threshold.

Parameters

Parameter Name	Parameter Meaning
OwnerIndex	Indicates the administrator of an NQA test instance.
TestName	Indicates the name of an NQA test instance.
TargetAddressType	Indicates the type of the destination address.
TargetAddress	Indicates the destination address.
Threshold	Indicates the user-defined threshold of an NQA test instance.
Index	Indicates the index of the result table.
RttMax	Indicates the maximum RTT.
MaxDelaySD	Indicates the OWD from the source to the destination.
MaxDelayDS	Indicates the OWD from the destination to the source.
JITTEROverThresholdsSD	Indicates the number of times that the JITTER from the source to the destination exceeds the threshold.

Possible Causes

This alarm occurs in the NQA test.

Cause 1: The threshold value was too small.

Cause 2: The network was busy.

Procedure

1. Run the display cpu-usage command in the system view to check whether the CPU has an excessive load.

If so, go to Step 3.
If not, go to Step 2.

2. In the NQA test view, run the display this command to know the current threshold. Then run the threshold jitter-sd command to modify the threshold as required. The recommended value is 20 ms. Perform the test again to check whether the alarm is cleared.

If so, go to Step 4.
If not, go to Step 3.

3. Collect alarm information and configuration information, and then contact technical support personnel.

4. End.
