Parameters
item-number: Specifies a reaction entry ID 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: Specifies 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: Specifies to check the average one-way jitter.
threshold-value: Specifies threshold values in milliseconds.
upper-threshold: Specifies the upper threshold in the range of 0 to 3600000.
lower-threshold: Specifies the lower threshold in the range of 0 to 3600000. It must not be greater than
the upper threshold.
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
Only successful probe packets are monitored. Failed probe packets are not counted.
Examples
# Create reaction entry 1 for monitoring the average destination-to-source jitter of UDP jitter packets. Set
the upper threshold to 50 milliseconds, and the lower threshold 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. If it exceeds the upper threshold, the state of the reaction entry is
set to over-threshold. If it is below the lower threshold, 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.
