Statistics are displayed in three ways:
•
By count (i.e., the number detected of each for the selected interval).
•
By rate (i.e., the number of each per second, as averaged over the selected
interval).

•
Graphically, as a percentage of each with respect to total network load

frames rate of 75% during a delta interval indicates that of all frames processed
by the selected interface, 75% were transmitted by that interface).

You can view performance for three different intervals:
•
Absolute
— Counts recorded since the selected module was last started.
•
Cumulative
— Counts recorded since the Performance window was opened.
•
Delta
— Counts recorded during a single polling interval that is set for
