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.
Unless otherwise stated, all the following commands, except display commands that can be run in all views,
need to be run in the NQA test instance view.
Procedure
Step 1 Run the ping command on the NQA client to check whether the route to the destination address
is reachable.
l If the route to the destination address is reachable, go to Step 2.
l If the route to the destination address is unreachable, see the section The Ping Operation
Fails.
Step 2 Run the display this command in the system view on the NQA client to check whether the value
of the parameter "nqa-jitter tag-version" is 2. When the value of this parameter is set to 1 (the
default value), this parameter is not displayed in the configuration file. This parameter is
displayed in the configuration file when its value is set to 2.
l If the value of the parameter "nqa-jitter tag-version" is 2, go to Step 3.
l If the value of the parameter "nqa-jitter tag-version" is not 2, go to Step 4.
Step 3 Run the display nqa-server command on the NQA server to check whether the nqa-server
udpecho ip-address port-number command has been configured on the NQA server.
l If the nqa-server udpecho ip-address port-number command has been configured on the
NQA server and is in the Active state, go to Step 4.
l If the nqa-server udpecho ip-address port-number command is not configured on the NQA
server, run the command to configure the NQA server. Note that the IP address of the NQA
server must be identical with the destination IP address configured through the destination-
address ipv4 ip-address command on the NQA client. Also, the port number configured on
the NQA server must be identical with that configured through the destination-port port-
number command on the NQA client.
– If the fault is rectified, go to Step 5.
– If the fault persists, 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
