CHAPTER 4: Traffic Measurement
The display will show a continuous reading of
traffic conditions on the network. Listed below are
explanations of the information that will appear
in the display window.
1sec Traffic
shows the average network
utilization over the last second and gives
an indication of current traffic levels.
Peak Traffic
is the highest one-second average
traffic over the duration of the test.
Collisions
shows the current collision rate over
the last second, expressed as a percentage
of total packets transmitted. Collisions are
counted when runt packets (shorter than a
valid minimum packet length) are detected.
The
Bar Graph
displays the instantaneous traffic
level, scaled from 0 on the left side of the
display to 60% on the right side.
For 10BASE-T networks, the bottom line will display
“No link pulse” whenever link to the hub is lost, and
will display “Wrong polarity” when reverse-polarity
link pulses are detected.
