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 total number of threshold violations in the
operation. The value range is 1 to 14999 for the ICMP jitter and UDP jitter operations, 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 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
