Statistics: Received and Transmitted Ethernet Frames
6-34
The graph shows the frames Port 1 has received over a period
since the switch’s last reset or since someone has last set the
counters to zero.
4. Select Transmit statistics to display a screen similar to
Figure 6-31, showing the frames transmitted by Port 1.
Figure 6-31 Transmitted Frames Graph for Port 1
Expect transmit errors to be very small. The switch may receive
a number of bad frames, but the switch must drop those and
send only good frames.

The sample graphs show the types of frames received or transmitted
by a switch or its individual ports since the last time the counters or
the switch were reset. The software keeps count of the number of
frames and creates a graph. The counters and the graph dynamically
increment as the switch processes frames over a period of time.
When the individual counters reach a maximum of 2
32
(over 4
billion), then the counters reset to zero. Because each counter resets
independently; your graph may become inaccurately skewed;
therefore, you need to reset the counters to get a new baseline on
frame statistics.
