The nqa command creates an NQA test and enters the NQA test view.
The undo nqa command deletes the configured NQA test.
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 case-sensitive character string. The length of a name without spaces ranges from 1 to 32 characters. The length of a name with spaces ranges from 3 to 34 characters. If a name contains spaces, the name must be enclosed with quotation marks (for example, "admin for test"). |
| test-name | Specifies the name of an NQA test instance. | The value is a case-sensitive character string. The length of a name without spaces ranges from 1 to 32 characters. The length of a name with spaces ranges from 3 to 34 characters. If a name contains spaces, the name must be enclosed with quotation marks (for example, "name for test"). |
| 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. Therefore, operators can collect network operation indexes in real time, such as total delay of HTTP, TCP connection delay, DNS resolution delay, file transfer delay, FTP connection delay, and DNS resolution error rate.
To check these performance indexes, you can create NQA test instances. The two ends in 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 including the running test instance will be deleted. In this scenario, you cannot perform any operation on each test instance.
Precautions
The undo nqa test-instance admin-name test-name command cannot delete a running NQA test instance.
The undo nqa all-test-instance command deletes all NQA test instances (including the running test instances).
