whether any errors were discovered in those frames,
display the Health screen (Figure 4-3):

Figure 4-3. Health Details
This screen enables you to look at the status of frames
transmitted across the link since AutoTest began. As you
can see, NetTool provides a breakout of the types of
errors it discovers. These detailed error statistics can help
you isolate device- and network-related problems.
The Health screen shown in Figure 4-3 displays
cumulative activity since you last ran AutoTest. You may
also want take a look at what is going on now and
simultaneously view the health of frames on both sides of
a connection.
To do this:
1. Select Toolkit from the Main menu.
2. From the Toolkit menu, select Health to display the
screen shown in Figure 4-4:

3. To change the view, move the cursor to Util or Bcast,
then press SELECT.
For example, selecting Util changes the view to
broadcast traffic, collision levels, or errors coming
from either device to which NetTool is connected.
