Statistics
Frame Size (Bytes) Packets
The Frame Size (Bytes) Packets Þelds indicate the number of packets (including
error packets) processed by the network segment that were of the noted length,
excluding framing bits but including frame check sequence bits. Packet sizes
counted are:
¥ 64
¥ 65-127
¥ 128-255
¥ 256-511
¥ 512-1023
¥ 1024-1518
The percentages displayed to the right of the numerical values for these Þelds
indicate what percentage of all packets transmitted on the network segment were
of the noted size. Unless the network segment has experienced a signiÞcant
number of runts and/or giants (which are not counted in this group), these
percentages will add up to 100. The pie chart in the center of the window provides
a graphical view of the percentage breakdown; colors in the pie chart correspond
to colors in the percentage display boxes. Values listed to the right of the pie chart
indicate peak delta values recorded since the statistics screen was launched, and
the date and time they occurred.
Viewing Total, Delta, and Accumulated Statistics
By using the Total, Delta, and Accum radio buttons located at the bottom of each
Statistics window, you can choose whether to view the total statistics count (since
the last time the device was initialized), the statistics count during the last polling
interval, or a fresh accumulation of statistics begun when the Accum button was
selected. The polling interval is user-conÞgurable; see the UserÕs Guide for
information on setting polling intervals.
