Frame Size Distribution View is available as a chart or a table. For the chart, the Bar
and
Pie buttons toggle the type of graphic display. The Pause/Resume button allows
you to pause or resume real-time update of the graph.
For both the chart and the table, each range of frame sizes is expressed as a
percentage of the total number of frames counted.
When using an NDIS module, the byte count in Frame Size Distribution view
includes the 4 bytes of the Frame Check Sequence; however, for other views, these
4 bytes are not counted for each packet. Therefore, the total-byte counters in other
views will be different than total-byte counters in Frame Size Distribution view.

Protocol Distribution as a chart can be viewed in many different ways, depending

•
Protocol Buttons select the types of protocol distribution you want to see. There
are four protocol buttons that change the protocols you are viewing in the
graph.
•
Frame/Byte Buttons select to view the distribution by byte count or frame count,
or can be used to select distribution relative to network capacity. There are three
buttons that control how the protocols are counted when displayed in the graph
