Token Ring Statistics
3-22 Port Level Statistics
Frequency Errors
The number of times the selected station has detected that the incoming signal’s
frequency differed from the expected frequency by more than allowed.
Total Errors
The total number of errors accounted for by the selected port.
The Station Timer Statistics Window
At the Station Timer Statistics window ( Figure 3-12 ), you can view the number of
frames, errors, and bytes processed by the selected station port over a
user-defined time interval (allowable time settings are 1 second to 23 hours, 59
minutes, 59 seconds). The displayed statistics will automatically update within
the time interval you have set at the Interval text box at the bottom of the screen.
Figure 3-12. Station Timer Statistics Window
Two fields directly above the bar graphs identify the currently selected port by its
board and port number and its MAC address.
Bar charts graphically represent the elapsed, average, and peak times that frames,
bytes, and soft errors are passing through the port. These charts are color-coded to
allow you to quickly scan the display and obtain needed information concerning
the port’s activity level. See
Viewing Elapsed, Average, and Peak Activity
Levels , page 3-2 , for details about the Timer Statistics chart measurements.
You can also refresh the statistics at any time by clicking on the
Clear
button. This
will refresh the Station Timer Stats window to collect new network statistics. (The
time under the Clear button will also update, indicating the last time that the
Timer Stats box was cleared.)
