1090 CHAPTER 86: NQA CONFIGURATION
Figure 321 Relationship between NQA client and NQA server
The NQA server listens to test requests originated by the NQA client and makes a
response to these requests. The NQA server can respond to requests originated by
the NQA client only when the NQA server is enabled and the corresponding
destination address and port number are configured on the server. The IP address
and port number specified for a listening service on the server must be consistent
with those on the client.
You can create multiple TCP or UDP listening services on the NQA server, with
each listening service corresponding to a specified destination address and port
number.
NQA Test Operation NQA can test multiple protocols. A test group must be created for each type of
NQA test. Each test group can be related to only one type of NQA test. Each test
group has an administrator name and an operation tag. The administrator name
and the operation tag uniquely identify a test group.
After you create a test group and enter test group view, you can configure related
test parameters. Test parameters vary with the test type. For details, see the
configuration procedure below.
For optional parameters common to different types of tests, refer to “Configuring
Optional Parameters for NQA Tests” on page 1109.
To perform an HW test successfully, proceed as follows:
1 Enable the NQA client.
2 Create a test group and configure test parameters according to the test type.
3 Perform the NQA test through the related enable command.
4 View the test results through the related display or debugging command.

After you enable the NQA client, you can create multiple test groups to perform
tests. In this way, you do not need to enable the NQA client repeatedly.
Configuring NQA Tests
n
■ You need to configure the NQA client and NQA server for TCP, UDP, and jitter
tests, while you need to configure only the NQA client for other tests.
■ You are not recommended to perform TCP, UDP, or jitter test on the ports from
1 to 1023 (known ports). Otherwise, the NQA probes will fail or the
corresponding services of this known port will be unavailable.
