The nqa-jitter tag-version command sets the packet version for a UDP Jitter test instance.
The undo nqa-jitter tag-version command restores the default packet version for a UDP Jitter test instance.
By default, the packet version of a UDP Jitter test instance is 1.
| Parameter | Description | Value |
|---|---|---|
| version-number | Specifies the packet version for a UDP Jitter test instance. | The value can be 1 or 2. |
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.
Configuration Impact
If the packet version of a UDP Jitter test instance has been configured, running the nqa-jitter tag-version command will override the previous configuration.
Precautions
No matter the version number of the UDP Jitter test packet is 1 or 2, you need to run the nqa-server udpecho command to configure the NQA server. Otherwise, the UDP Jitter test instance will fail due to timeout.
