the NMS.

reaction checked-element { jitter-ds | jitter-sd }

Use reaction checked-element { jitter-ds | jitter-sd } to configure a reaction entry for monitoring one-way

jitter in the NQA operation.

Use undo reaction to delete the specified reaction entry.

Default

No reaction entry for monitoring one-way jitter is configured.

Parameters

item-number: Assigns an ID to the reaction entry, in the range of 1 to 10.

jitter-ds: Specifies the destination-to-source jitter of each probe packet as the monitored element (or

performance metric).

jitter-sd: Specifies source-to-destination jitter of each probe packet as the monitored element.

threshold-type: Specifies a threshold type.

accumulate accumulate-occurrences: Checks the maximum number of threshold violations in the

operation. The value is in the range of 1 to 14999 for the UDP jitter operation, and 1 to 59999 for the

voice operation.

average: Checks the average one-way jitter.

threshold-value: Specifies threshold range in milliseconds.

upper-threshold: Specifies the upper limit in the range of 0 to 3600000.

lower-threshold: Specifies the lower limit in the range of 0 to 3600000. It must not be greater than the

upper limit.

action-type: Specifies what action to be triggered. The default action is none.

none: Specifies the action of only displaying results on the terminal display.
