5-4 Monitoring Ring and Station Statistics
Using the Reverse MAC Button
The Reverse MAC button, available in the Ring and Station Statistics window,
enables you to toggle between Token Ring and Ethernet MAC address formats.
Token Ring MAC addresses (the default address format in this window) are
displayed in the reverse bit order of Ethernet MAC addresses. The Ethernet MAC
format is the more recognizable format; therefore, the Reverse MAC button can be
used to enable the network manager to recognize the MAC addresses more easily.
To use the Reverse MAC button:
1. Highlight the station whose MAC address format you would like to change.
2. Click mouse button 1 on ; the station’s MAC address format will
be changed.
3. Repeat the process to toggle back to the original Token Ring MAC address
format.
Refreshing the Station List
Once it is displayed, the information in the station list is static, and will not reflect
changes to the ring. You can update the station list by clicking mouse button 1 on
, located at the bottom of the window. Using the Refresh button will
display the current configuration of your ring.
Monitoring Ring and Station Statistics
Ring and Station Statistics can be viewed in pie chart, graph, or meter form. The
ring statistics will reflect the activity of the entire ring, while the station statistics
will reflect only the station that is highlighted when you choose the chart, graph,
or meter you wish to display.
There are five pre-formatted pie charts you can display to view statistics specific
to the ring as a whole: general statistics, protocols, frame sizes, isolating errors,
and non-isolating errors. For viewing statistics specific to an individual station,
three pre-formatted charts are available: general statistics, isolating errors, and
non-isolating errors.
You can customize ring-specific or station-specific meters by using 29 available
ring-related variables, or 13 available station-related variables. With SPMA, you
can run up to 25 meters simultaneously.
NOTE
When you toggle the MAC address format, the neighbor and ring port addresses are not
affected; they will always be displayed in Token Ring format.
