R3721-F3210-F3171-HP High-End Firewalls High Availability Command Reference-6PW101

74
lower-threshold: Lower threshold, which ranges from 0 to 3600000. It must not be greater than the upper
threshold.
Description
Use reaction checked-element { owd-ds | owd-sd } to configure a reaction entry for monitoring the
one-way delay. You cannot edit a reaction entry. To change the attributes in a reaction entry, use the
undo reaction command to delete this entire entry and start over.
Use the undo reaction command to delete a specified reaction entry.
By default, no reaction entry for monitoring the one-way delay is configured.
Only successful probe packets are monitored. The data of a failed probe packet is not counted.
No actions can be configured for a reaction entry of monitoring one-way delays. The monitoring results
and statistics, however, can be displayed by the display nqa reaction counters and display nqa statistics
commands.
Examples
# Create reaction entry 1 for monitoring the destination-to-source delay of every UDP jitter probe packet.
Set the upper threshold to 50 milliseconds and lower threshold to 5 milliseconds. Before the NQA test
group starts, the initial state of the reaction entry is invalid. The destination-to-source delay is calculated
after the response to the probe packet arrives. If the delay is out of the threshold range, the state of the
reaction entry is set to over-threshold; otherwise, the state is set to below-threshold. Once the state of the
reaction entry changes, a trap message is generated and sent to the network management server.

Parameters
item-number: ID for a reaction entry, which ranges from 1 to 10.
threshold-type: Specifies a threshold type.
accumulate accumulate-occurrences: Total number of lost packets in a test. It ranges from 1 to 15000 for
UDP jitter tests.
action-type: Specifies what action to be triggered to react to certain measurement conditions and it
defaults to none.
none: Specifies to only record events for terminal display, and not to send any trap messages.
