The Status column in the main pane identifies the
channel consuming the most bandwidth.
The preview pane displays up to five of the most
active channels. For each channel, you can view
bandwidth utilization (%) and transmission rates
(packets per second). This information is
continuously updated.
2. To view channel details, do one of the following:
• To focus on a particular channel, tap the desired
hyperlink in the preview pane.

The Channel Utilization screen is displayed. On this
screen, you can view (in graphic and tabular form)
the types of traffic (for example, FCS Errors or
Retries) seen on the network and the percentage of
bandwidth each traffic type is consuming.
Note that you can look at a different channel’s
statistics. To do this, select the desired channel from
the Channel box.
You can also tap the graph and look at statistics for
a particular time period. The statistics for the time
period you select are also given in the accompanying
table. To change the sampling frequency (default = 5
