    Running an RFC 2544 Benchmarking Test

    Use this procedure to run an RFC 2544 benchmarking test on the BTI805, BTI821, or BTI822 devices.

    The tests specified in RFC 2544 are useful to determine whether an Ethernet service complies with service level agreements. These tests apply to EPLINE and EVPLINE services only.

    1. Right-click a service in the Network tree and select RFC 2544 >Run Tests.

      The Rfc 2544 dialog appears.

    2. Select the test parameters as follows:
      • Throughput— This is always selected. The other tests require the throughput test to be enabled. The throughput test measures the maximum rate that can be processed within the specified Acceptable Loss constraint.
      • Frame Loss Ratio— Select to run the frame loss ratio test. This test measures the frame loss ratios for different ingress traffic rates.
      • Latency— Select to run the Latency test.
      • Endpoint— Select the endpoint of the circuit where the test is to be initiated.
      • Frame Size 1 through Frame Size 6— Select the six different frame sizes to use for the test(s).
      • Cos Type— Select the class of service type from the pulldown menu. Select EPU (EVC per UNI) if you want to use the EVC class of service. Select MANUAL if you want to manually specify the class of service.
      • Cos Level— Select the class of service level if the Cos Type is set to MANUAL.
    3. Select the Details tab to configure the detailed test settings.

    4. Select the throughput test parameters as follows:
      • Oper-Way— Select DUAL_ENDED to generate test traffic from both ends, or LOOPBACK to loop back the test traffic at the remote end.
      • Max. Trial Times— Specify the maximum number of trials to run. The minimum value for this parameter is 5.
      • Acceptable Loss— Specify the percentage of frames that can be lost (and the outcome still considered to be acceptable). If this is set to 0, the throughput test measures the maximum rate that can be processed with no loss of frames.
      • Max. Rate— Specify the starting traffic rate (Mbps) for the test.
      • Duration— Specify the duration of the test in seconds.
      • S. Trial— Specify the number of successive trials that must be successful before the test at the current frame size is stopped. A trial is successful if the number of lost frames is within the Acceptable Loss constraint.
    5. Select the frame loss ratio test parameters as follows:
      • Oper-Way— Select DUAL_ENDED to generate test traffic from both ends, or SINGLE_ENDED to generate test traffic from one end, or LOOPBACK to loop back the test traffic at the remote end.
      • Granularity— Specify the percentage of the maximum frame rate to step down for each successive trial. The maximum frame rate is the frame rate that achieves 100% link utilization for the frame size being used. The rate is stepped down from the maximum frame rate successively if frame loss occurs.
      • Duration— Specify the duration of the test in seconds.
      • S. Trial— Specify the number of successive trials that have no lost frames before the test at the current frame size is stopped.
    6. Select the latency test parameters as follows:
      • Oper-Way— Select DUAL_ENDED to generate test traffic from both ends, or LOOPBACK to loop back the test traffic at the remote end.
      • Duration— Specify the duration of the test in seconds.
    7. Select Background Traffic to enable background traffic in the latency tests.
    8. Click Run.

      You can monitor the status of the test through the View >Server >Tasks window.

    9. View the test results when the test is finished.
      1. Right click the service in the Network tree and select RFC 2544 >Show Results.

        This command retrieves the most recent, completed RFC 2544 tests from the NE and lists them in the Rfc Test Result List.

        Note: Once PSM retrieves the test results, it stores them in its local database and makes them available for display (even if the test results are subsequently deleted from the NE).

      2. Select the test you want to view and click Open.

        A new tab opens showing the test that you have selected.

      3. Click the chevron in the upper right corner to view the test results.

        The test results are organized as shown in the following figure:

      4. To see the results of a specific test, click the associated chevron.

        For example, these are the results of the throughput test:

    10. To export the test data to an Excel file, click Export and save the file.
