When we use Huawei NE series routers, we sometimes encounter problems. How can these problems be solved? We provide the Troubleshooting Guide to help you.
If you encounter the UDP Jitter Test Result Is "Failed", "No Result" or "Packet Loss", perform the following steps:
1. 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.
2. Run the display this command in the NQA test instance view to check whether the parameter frequency is configured.
§ If the parameter frequency is configured, compare the value of the frequency and that of the (interval*probe-count*jitter-packetnum). To ensure that the UDP Jitter test instance can be complete normally, the value of the frequency must be greater than that of the (interval*probe-count*jitter-packetnum). If the value of the frequency is smaller than that of the (interval*probe-count*jitter-packetnum), you run the frequency interval command in the NQA test instance view to increase the value of the frequency.
§ If the frequency is not configured or the fault persists after the frequency is set to proper value, go to Step 3.
3. Run the display this command in the NQA test instance view to check whether the parameter fail-percent is configured.
§ If the fail-percent is configured, run the undo fail-percent command in the NQA test instance view to delete the fail-percent. If the fault persists after the fail-percent is deleted, go to Step 4.
§ If the fail-percent is not configured, go to Step 4.
4. If the fault persists, collect the following information and contact technical support personnel.
