Viewing the Error Table | Cabletron Systems TRMMIM guide

Ring Map

The calculation mode you select will be used to determine the statistics values displayed in the Quick Info Pop-upwindow (see page 3-6), the Error Table (see page 3-14), and in the Find feature which displays the stations with the lowest and highest occurrences of certain statistical values (see page 3-28).

To set the calculation mode:

1.Click on at the top of the Ring Map window.

2.Drag down to Set Calculation Mode, and release. The Set Calculation Mode window, Figure 3-7, will appear.

3.Click to select the desired mode of calculation: Rate, Cumulative, or Delta.

4.Click on OK to accept the calculation mode, or Cancel to exit without changing the calculation mode.

To refresh the cumulative statistics and begin re-calculating them, bring up the Set

Calculation Mode window, click on , and then on .

Viewing the Error Table

The Error Table provides a ranking of ring stations according to the total number of errors or the total of an individual error type detected by each station. Stations are listed hierarchically, from greatest to least; each station is identiﬁed by MAC address as well as rank.

In addition to the ranking and selected error statistic, the table also provides the total number of frames and bytes processed by each station.

Error table rankings are determined based on the calculation mode currently in effect, and statistical values are displayed in that mode; note that changing the calculation mode may also change the ranking, since the values used for ranking will be different. Only the top ten stations will appear in the list; stations reporting identical numbers of errors — including 0 — are listed in an arbitrary order.
