HP FlexFabric 12500 Series Network Management And Monitoring Command Reference page 63

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 total 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.
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 undo
reaction to delete the entry first and reconfigure 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,
setting 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,
setting 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 exceeds 100 (included), 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.
