function.
NQA supports three types of trap messages as defined in the DISMAN-PING-MIB.

NQA also supports the sending of trap messages to the NM station when the uni-directional
transmission delay or the round-trip transmission delay exceeds the threshold.

Trap messages carry information such as destination IP address, operation status, destination IP
address of the test packet, minimum RTT, maximum RTT and total RTT, number of sent probe
packets, number of received packets, RTT square sum, and time of the last successful probe.

Trap message sent when an NQA probe fails
This message checks whether the probe Echo packets are received.
If the number of packets that have no responses reaches the upper limit, trap messages are
sent to a specified NM station.
Trap message sent when an NQA test fails
This message checks whether the test fails.
If the number of the times that a test fails exceeds the limit, trap messages are sent to a
specified NM station.
Trap message sent when an NQA test is successful
This message checks whether the test is successful.
If Echo packets are received during an NQA test, trap messages are sent to a specified NM
station.
For all tests supporting traps, if the round-trip transmission delay exceeds the threshold and
the trap function is enabled, trap messages are sent to the NM station with the specified IP
address.
For all the Jitter tests, if the uni-directional transmission delay exceeds the threshold and
the trap function is enabled, trap messages are sent to the NM station with the specified IP
address.
