The most common errors occur when the endpoint is not installed or is installed improperly. If this is the case, you will see error CHR0200: “The TCP connection attempt timed out,” or CHR0204: “No partner program is waiting to accept this TCP sockets connection.”
If you see either of these errors, check the endpoint computers included in the Diagnosis and ensure the endpoint is installed and running. The endpoint documentation includes advice for ensuring the endpoint is running and for restarting it, if necessary. For more information, see Section 1.7, NetIQ Performance Endpoints.
Equally, you may see CHR0401: “Vivinet Diagnostics could not discover a Performance Endpoint near phone or voice gateway %1 with subnet mask %2.” This error may occur when you run a Diagnosis using telephones as Target Devices. For such diagnoses, Vivinet Diagnostics still attempts to locate endpoints to run diagnostic testing. If you have not installed endpoints in the subnets where the IP phones are located, or in the same subnet as a POTS phone’s voice gateway, you will see this message. Just install an endpoint in the subnet indicated in the message and run the Diagnosis again.
Occasionally Vivinet Diagnostics detects an error in an endpoint computer’s high-precision timers and generates error CHR0359. If you see this error, run the Diagnosis again.
Other types of common errors invalidate or impede the Diagnosis unless you make configuration changes. For example, when one of the endpoints is powered off while the Diagnosis is running, your results will show CHR0200. Similarly, error CHR0125 indicates an endpoint included in the Diagnosis is an older endpoint version and does not support the necessary diagnostic testing performed by Vivinet Diagnostics. Install the latest version of the endpoint on the affected computer. For more information, see Section 1.7, NetIQ Performance Endpoints.
If you installed Performance Endpoints on computers running Microsoft Vista, you will get the following error when performing endpoint-to-endpoint diagnoses between those computers:
Layer 2 Trace could not be performed starting from a Phone or Endpoint because the MAC Address is unknown. Check the Error Log for further details.
The built-in security in Microsoft Vista prevents Vivinet Diagnostics from completing a Diagnosis between endpoints. Performance Endpoints are not supported on Microsoft Vista.
In the unlikely event you are unable to synchronize the clocks on both endpoint computers, it is possible you will not get performance results for certain call quality metrics. However, Vivinet Diagnostics will not report an error if your clocks are not synchronized. You will notice only that expected results do not appear in the Results tab. If synchronization seems to be the problem, rerun the Diagnosis.
If you receive endpoint errors, save your Diagnosis configuration first, and then debug the endpoint problem.
