The following sections discuss the fields on the DEVICE STATISTICS
screen and provide instructions for using them.
DEVICE STATISTICS
The DEVICE STATISTICS counter mode field at the top of the screen
(Figure 4-9 shows an sample screen in the TOTAL counter mode) displays
the method used for compiling device statistics. The method is selected
from the corresponding counter mode field located at the bottom of the
screen.
The MicroMMAC-T compiles and displays statistics from three separate
counter modes:
• ACCUMULATE: This mode lets you initiate a new statistic count for
a specified time period (procedure described below).
• DELTA: This mode automatically displays statistics describing
network performance since the last screen refresh (3 to10 seconds).
