NQA Test Operation
An NQA test operation involves the following steps:
1) The NQA client constructs packets with the specified type, and sends them to the peer device.
2) Upon receiving the packet, the peer device replies with a response with a timestamp.
3) The NQA client computes the packet loss rate and RTT based on whether it has received the
response and the timestamp in the response.
NQA Configuration Task List
To perform TCP, UDP jitter, UDP echo or voice tests, configure the NQA server on the peer device.
Complete the following task to enable the NQA server:

Required for TCP, UDP echo, UDP jitter and voice
tests
To perform an NQA test successfully, make the following configurations on the NQA client:
1) Enable the NQA client;
2) Create a test group and configure test parameters according to the test type. The test parameters
may vary with test types;
3) Start the NQA test.
To view test results about the test, use the display or debug commands.
