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 threshold violations in a test. It ranges from 1 to
15000 for UDP jitter tests.
average: Packet average round-trip time in a test.
threshold-value: Specifies threshold values in milliseconds.
upper-threshold: Upper threshold, which ranges from 0 to 3600000.
lower-threshold: Lower threshold, which ranges from 0 to 3600000. It must not be greater than the upper
threshold.
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.
trap-only: Specifies to record events and send SNMP trap messages.
Description
Use reaction checked-element rtt to configure a reaction entry for monitoring packet round-trip time. 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 packet round-trip time is configured.
Only successful probe packets are monitored. The data of a failed probe packet is not counted.
Examples
# Create reaction entry 1 for monitoring the average round-trip time of UDP jitter probe packets. 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. After each test, the average packet round-trip time
is checked. If it is out of the threshold range, the state is set to over-threshold; otherwise, the state is set
to below-threshold. Once the reaction entry state changes, a trap message is generated and sent to the
network management server.
