The nqa command creates an NQA test instance and enters the NQA view.
The undo nqa command deletes an NQA test instance.
nqa test-instance admin-name test-name
undo nqa { test-instance admin-name test-name | all-test-instance }
| Parameter | Description | Value |
|---|---|---|
| admin-name | Specifies the administrator of an NQA test instance. | The value is a string of 1 to 32 characters without question marks (?), spaces, or hyphens (-).
NOTE:
If the string is enclosed in double quotation marks (" "), the string can contain spaces. |
| test-name | Specifies the name of an NQA test instance. | The value is a string of 1 to 32 characters without question marks (?), spaces, or hyphens (-).

| all-test-instance | Specifies all NQA test instances. | - |
Usage Scenario
The NQA is an integrated network test function. NQA test instances can accurately detect network running status, collect test statistics, and reduce costs.
NQA measures the performance of different protocols running on the network. NQA allows enterprise users to collect network operation indexes in real time, such as total delay of the HTTP, TCP connection delay, DNS resolution delay, file transmission delay, FTP connection delay, and DNS resolution error ratio.
To check these performance indexes, you can create NQA test instances. The two ends of an NQA test are called the NQA client and NQA server. The NQA client is responsible for initiating an NQA test. After receiving packets, the NQA server sends response messages to the NQA client. You can learn about the running status of a corresponding network according to the returned packets.
Configuration Impact
After the undo nqa all-test-instance command is run, all NQA test instances except the running test instance will be deleted.
Precautions
A running test instance cannot be deleted.
