6.33.1 Establishing the Configuration Task
Before configuring the trap function, familiarize yourself with the applicable environment,
complete the pre-configuration tasks, and obtain the required data. This can help you complete
the configuration task quickly and accurately.
Applicable Environment
Trap messages are generated regardless of whether the NQA test is successful or fails. You can
control whether to send trap messages to the NM station by enabling or disabling the trap
function.
NQA supports three types of trap messages as defined in the DISMAN-PING-MIB.
l
Trap message sent when an NQA probe fails
It aims at checking 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.
l
Trap message sent when an NQA test fails
It aims at checking 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.
l
Trap message sent when an NQA test is successful
It aims at checking whether the test is successful.
If Echo packets are received during an NQA test, trap messages are sent to a specified NM
station.
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.
l
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.
l
For all the Jitter tests ( LSPJitter and PathJitter not included ), 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.
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.
Pre-configuration Tasks
Before configuring the trap function, complete the following tasks:
l
Configuring routes between the NQA client and the NM station
l
Creating an NQA test and configuring related parameters correctly
Data Preparation
To configure the trap function, you need the following data.
