NQA Test Operation 
An NQA test operation is as follows: 
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 
For TCP, UDP jitter, UDP echo or voice tests, you need to configure the NQA server on the peer 
device. 
Follow these steps to enable the NQA server: 
Task  Remarks 
Configuring 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; 
After the test, you can view test results using the display or debug commands. 
Complete these tasks to configure NQA client:
