NQA Overview

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.

Configuring NQA

ICMP Echo Test Configuration Example

Network diagram

Figure 1-1 ICMP echo test network diagram

 

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.
