Network Quality Analyzer (NQA) analyzes
network performance, services and service quality by sending test packets, and
provides you with network performance and service quality parameters such as
jitter, TCP connection delay, FTP connection delay and file transfer rate.
With the NQA test results, you can:
1)
Know network performance in time and then take
corresponding measures.
2)
Diagnose and locate network faults.
I. Network diagram
Figure 1-1 ICMP echo test network diagram
II. Networking and configuration
requirements
Use NQA to perform ICMP-echo test to see whether
the NQA client (Switch A) can send packets to the specified destination (Switch
B) and test the roundtrip time of the packets.

In a UDP jitter
test, a group of probe packets are sent in a probe, and this group of packets
corresponds to one history record. Therefore, to know the results of a UDP
jitter test, you are recommended to use the display nqa result command
to view the probe results, rather than the display nqa history command
to view the history record.
