Clicking on the Update button, located in the upper left corner of the blocked-
off Station Table area, causes the program to update the contents of the
Station Table.
The button located directly to the right of the Update button in the upper left
corner of the blocked-off Station Table area, is a two-selection button that
affects the display of statistical information listed in the table. This is a
current-state display button, with the readout identifying whichever selection
is currently selected. Selecting Totals displays the Frames statistics as totals
since the TRBMIM was initialized. Selecting Deltas displays the difference
between the current totals value and the value at the time of the last update.
The button located directly to the right of the Totals/Deltas button is a two-
selection button that affects the display of the station addresses, toggling the
format between MAC (Physical) and Canonical (Ethernet) address formats.
This button is an alternate-state display button, with the readout identifying
whichever format is currently selected.
Each of these address formats consists of six pairs of BCD numbers, each pair
separated by a colon, with the whole representing an 89-bit binary value. The
distinction between these formats is that the Canonical address format sends
the binary bits low-order bit Þrst, while the MAC address format sends the
binary bits high-order bit Þrst. Consequently, a pair having a binary value of
10111000 will be represented by a Canonical address of B8, whereas the
MAC-format version of that same value will be read as a binary value of
00011101, listed as a MAC value of 1D.
In addition, there are three selection buttons located in the lower left corner of
the blocked-off table area. Each of these buttons provides access to a different
station-related function pertaining to whichever station entry in the table is
highlighted when the button is selected, as follows:
The Station Detail button opens the Station Detail view, which is described
in Token Ring Station Detail View, starting on page 3-38. (You can also open
this same view by double-clicking on a station entry in the table, itself.)
The Station Alarms button opens the Station Alarms dialog box, which is
described in Station Alarms Dialog Box, starting on page 3-40.
