This section will describe how to Save a RFC2544 Stress Test.
After performing a stress test, select STORAGE from the main stress test
screen. Select to SAVE the stress test data collected internally or
externally onto a flashdrive. For saving to flashdrive:
The files are placed into the LANDATA directory, under the name entered
on the LanExpert when the files were saved. The previous binary
file (username.STT) is still saved in the LANDATA directory. This .STT file
allows the LanExpert to recall the data at a later time from the unit.
The CSV files placed into the sub-directory with the user defined name
are as follows -
TPUT.CSV - this is the throughput stress test results. If no
throughput test was performed then this file does not exist. Each line of
the this file has the format <frame size, frames per second, %utilization>
(e.g. 64,12345678,99); NOTE - unlike the display the frames per second
data is always in units of 1fps (i.e. it NEVER has a K character on the end
and scaled in 1000’s).
LATENCY.CSV - this is the latency stress test results. If no
latency test was performed then this file does not exist. Each line of the
this file has the format <frame size, min, avg, max> (e.g. 64,5,5,6); NOTE -
unlike the display, the data is always in integer microseconds.
LOSS.CSV - this is the frame loss test results. If no frame loss
test was performed then this file does not exist. The first line has the
format 0,%,%,%.... where each % is the percentage frame rate for the
corresponding column. The remaining lines have the format <frame
size,loss rate,loss rate>. Where the loss rate is in integer percent (NOTE -
if the % character is missing then the data was not actually measured).
BTB.CSV - this is the back-to-back test results. If no back-to-
back test was performed then this file does not exist. Each line of this file
has the format <frame size, max frame burst>.
Use the Excel Macro RFC2544 Report Generator from the
website to make a Printable Stress Test Report.
NOTE - Stress test data saved (internal or external) using this version or
an earlier version can be recalled and then resaved with this version in
order to generate the CSV files.

WARNING: DO NOT SAVE DATA COLLECTED FROM AN ABORTED
STRESS TEST. Tests not actually performed might yield random data in
the CSV files.
WARNING: DO NOT DISCONNECT THE USB DRIVE UNTIL THE
<SAVING xxx%> TEXT GOES AWAY ON THE LANEXPERT
SCREEN.
THIS MIGHT TAKE SEVERAL SECONDS TO SAVE AND IT MIGHT
APPEAR “STUCK” BUT DO NOT UNPLUG USB. THE USB DRIVE
WILL NEED TO BE REFORMATTED IF YOU DO THAT.
