Troubleshooting Procedure
NOTE
Saving the results of each troubleshooting step is recommended. If your troubleshooting fails to correct
the fault, you will have a record of your actions to provide Huawei technical support personnel.
All the following commands, except the display commands, are used in the NQA test instance view. The
display commands can be used in any views.
Procedure
Step 1 Run the display nqa-agent admin-name test-name [ verbose ] command on the NQA client or
the display this command in the NQA test instance view to check whether the TTL is configured.
l 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.
l 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.
Step 2 Run the display nqa-agent admin-name test-name [ verbose ] command on the NQA agent or
the display this command in the NQA test instance view to check whether the parameter
frequency is configured.
l If the parameter frequency is configured, compare the value of the frequency and 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 greater than that of the (interval
x probe-count x jitter-packetnum). If the value of the frequency is less 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.
l If the frequency is not configured or the fault persists after a proper frequency value is set,
go to Step 3.
Step 3 Run the display nqa-agent admin-name test-name [ verbose ] command on the NQA agent or
the display this command in the NQA test instance view to check whether the parameter fail-
percent is configured.
l 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.
l If the fail-percent is not configured, go to Step 4.
Step 4 If the fault persists, collect the following information and contact Huawei technical support
personnel:
l Results of the preceding troubleshooting procedures
l Configuration files, log files, and alarm files of the devices
