55
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 the action to be triggered. The default action is none.
none: Specifies the action of displaying results on the terminal display.
trap-only: Specifies the action of displaying results on the terminal display and meanwhile sending
SNMP trap messages to the NMS.
Usage guidelines
You cannot edit a reaction entry after it is created. To change the attributes in a reaction entry, use
the undo reaction command to delete the entry, and then configure a new one.
Only successful probe packets are monitored. Statistics about failed probe packets are not collected.
Examples
# Create reaction entry 1 for monitoring the average destination-to-source jitter of UDP jitter packets,
and set the upper limit to 50 milliseconds and the lower limit to 5 milliseconds. Before the NQA
operation starts, the initial state of the reaction entry is invalid. After the operation, the average
destination-to-source jitter is checked against the threshold range. If it exceeds the upper limit, the
state of the reaction entry is set to over-threshold. If it is below the lower limit, the state is set to
below-threshold. Once the state of the reaction entry changes, a trap message is generated and sent
to the NMS.

# Create reaction entry 2 for monitoring the destination-to-source jitter of UDP jitter probe packets,
and set the upper limit to 50 milliseconds, and the lower limit to 5 milliseconds. Before the NQA
operation starts, the initial state of the reaction entry is invalid. After the operation, the
destination-to-source jitter is checked against the threshold range. If the total number of threshold
violations reaches or exceeds 100, the state of the entry is set to over-threshold. Otherwise, the state
of the entry is set to below-threshold. Once the state of the reaction entry changes, a trap message is
generated and sent to the NMS.

Use reaction checked-element { owd-ds | owd-sd } to configure a reaction entry for monitoring the
one-way delay.
Use undo reaction to delete the specified reaction entry.
