User Guide

1. From the Home panel, go to TEST,
The test configuration panel is displayed.
2. Go to Performance objectives,
3. Select RFC 2544.
Note: You must enable the RFC 2544 test before you are allowed to enter in this
menu.
4. Enter the thresholds for Minimun throughput (%), Maximum latency, Maximum
frame loss (%), Minimum frame burst (fr), Maximum recovery time.
Note: Each specific test has to be individually enabled before you can set the per-
formance objective for it.
7.1.7. Getting Test Results
The RFC 2544 provides a description of the way test results must be presented to the
user. Normally, these results are displayed as tables. Each row represents the test
frame length or bit rate and columns are usually test results like throughput, latency or
others.
The RFC 2544 results can be evaluated as pass or fail. Failed results are represented
with red color. One test is considered to fail it at least one test result fails. The whole
RFC 2544 fails if one particular test result fails. The global Pass / Fail can be checked
at any moment, even before the end of the test from the Summary panel.
Once the test has been configured, it can be started at any time with the help of the run
button. You can wait to the test to finish but it is also possible to check partial test results
at any moment. To do that follow these steps:
1. From the Home panel, go to RESULTS,
The test port results panel is displayed.
2. Select either Port A or Port B to enter in the port specific results.
Note: If you have configured Test method to One-way (A > B), the RFC 2544
Back-to-back frames Sets a performance objective for the RFC 2544 back-to-back
frames test. The test is considered to fail if the back-to-back
frames result is smaller than the configured threshold and it
is considered to pass otherwise.
System recovery Sets the performance objective for the RFC 2544 system
recovery time test. The test fails if the system recovery time
result is longer than the threshold and passes otherwise.
