The nqa-jitter tag-version command sets the packet version for a jitter test instance.
The undo nqa-jitter tag-version command restores the default configuration.
| Parameter | Description | Value |
|---|---|---|
| version-number | Specifies the packet version for a jitter test instance. | The value can be 1 or 2. The default value is 1. |
Usage Scenario
Version 1 does not support unidirectional packet loss statistics. Version 2 produces more accurate packet statistics, which helps network administrators to locate network faults and detect malicious attacks towards the network. After version 2 and collecting the packet loss across a unidirectional link are enabled, you can view the packet loss across the link from the source end to the destination end, from the destination end to the source end, or in an unknown direction in the test results. Therefore, configuring version 2 is recommended.
Precautions
No matter the version number of the jitter test packet is 1 or 2, you need to configure the NQA server. Otherwise, the UDP jitter test instance will fail due to timeout.
