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.
Procedure
Step 1 Run the display ip routing-table command on the NQA client to check whether the route along
the test path exists.
l If the route exists, run the ping command to check whether devices can successfully ping
each other.
– If devices can successfully ping each other, go to Step 2.
– If devices cannot successfully ping each other, see The Ping Operation Fails.
l If the route does not exist, run the corresponding command to reconfigure the route.
Step 2 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 source IP address
is configured.
l If the source IP address is configured, run the display ip interface brief on the NQA client
to check whether the interface configured with the source IP address exists.
– If the interface exists, run the display ip routing-table command on the NQA server to
check whether the route to the source IP address exists.
– If the route exists, run the ping command to check whether the source IP address is
reachable.
