RFC2544 Test Sequence Home
Select RFC2544/NE Test as the test type on the Menu to perform RFC-2544 tests.
Use the ' Loop Contro l' ( ) button to set a loop if necessary.
Left Column - Test Basics
Type : Determine the type of RFC2544 test to perform.
• An RFC2544 test tests a device by transmitting various frame lengths at
different rates to find the maximum throughput rate.
• An NE test stresses a NE at a variety of rates, which you define.
Run Continuously : N/A. The RFC2544 test will run continuously when this is set to
On.
• Once the test sequence is completed, the module will run the sequence again
without saving the test results. This allows RFC2544 to be used as a long
term test.
Estimated Test Time : View an estimation of how long it will take to run theselected
tests, in a days, hours, minutes format.54qaz\`z`QRFTG12Choose the Tests to Run
To select a throughput or NE test to run , press its button to turn it On. The
Estimated Test Time reflects the predicted test run time for the tests selected.
• You may run several tests in sequence.
Trial
Description
Set at On, the RFC2544 Trial Description runs before the main
test starts. If it fails, no further testing occurs.
Throughput This test uses a binary search to determine the maximum traffic
rate (expressed as a percentage) the DUT can pass without
losing any frames.
Latency Determines the round trip delay of the frame through the DUT.
Latency Mode :
• Standard follows the guidelines of RFC 2544, which
can take several hours for a complete test.
• Quick measures the round trip delay while it is
performing the Throughput test and takes no extra
time. Results from failed throughput tests are
discarded, and only the results from the highest
successful throughput test are kept and recorded.
Frame Loss Generates a table that shows the percentage of lost frames as a
function of frame rate, expressed as a percentage.
Back to
Back
Determines the maximum number of frames sent back to- back
at 100% frame rate that the DUT can process without losing
frames
DUT Type Select the type of far end device under test: ROUTER or
BRIDGE.
Multi-Port
View or set the port connections. RFC-2544 tests require the use of two ports. RFC
2544 may be run between two different ports such as:
XFP - SFP
XFP - RJ-45
SFP - SFP
SFP - RJ-45
