The UDP Jitter Test Result Is "Failed", "No Result", or "Packet Loss"
Context
The UDP jitter test result displayed in the display nqa
results command output can be failed, no result, or packet loss. In the command output,
- If the Completion field is displayed as failed, the test fails.
- If the Completion field is displayed as no result, the test has no result.
- If the lost packet ratio field is not 0%, packet loss occurs.
This fault is commonly caused by one of the following:
- A drop record exists in the UDP jitter test result.
- A busy record exists in the UDP jitter test result.
- A timeout record exists in the UDP jitter test result.
- The TTL expires.
- The parameter frequency is incorrect.
- The parameter fail-percent is incorrect.
Generally, the following commands are used in the NQA test instance view. Only the display commands can be used in any view.
Procedure
- Run the display nqa-agent admin-name test-name [ verbose ] command on the NQA client or run the display this command
in the NQA test instance view to check whether the TTL is configured.
- If the TTL is configured, you can run the ttl number command in the NQA test instance view to set the value of the TTL to 255. If the fault persists after the TTL is set to 255, go to Step 2.
- If the TTL is not configured, you can run the ttl number command in the NQA test instance view to set the value of the TTL to 255. If the fault persists after the TTL is set to 255, go to Step 2.
- Run the display nqa-agent admin-name test-name [ verbose ] command on the NQA client or run the display this command
in the NQA test instance view to check whether the parameter frequency is configured.
- If the parameter frequency is set, compare the value of the frequency with that of the (interval x probe-count x jitter-packetnum). To ensure that the UDP Jitter test instance can be complete normally, the value of the frequency must be larger than that of the (interval x probe-count x jitter-packetnum). If the value of the frequency is smaller than that of the (interval x probe-count x jitter-packetnum), run the frequency interval command in the NQA test instance view to increase the value of the frequency.
- If the frequency is not set or the fault persists after a proper frequency value is set, go to Step 3.
- Run the display nqa-agent admin-name test-name [ verbose ] command on the NQA client or run the display this command
in the NQA test instance view to check whether the parameter fail-percent is set.
If the parameter fail-percent is set, run the undo fail-percent command in the NQA test instance view to delete the parameter fail-percent.
