5-4 The Station List Window
Viewing Station Timer Statistics
To view Station Timer Statistics:
1. Click on the Timer Statistics radio button at the bottom left of the window.
2. Double-click on the station for which you want to view Timer Statistics. The
station will be highlighted to show it is selected, and the Station Timer
Statistics window will appear.
For a complete explanation of this window, refer to The Station Timer Statistics
Window
, in the Token Ring Statistics chapter of this guide.
Note that you can also view Timer Statistics for the MicroMMAC-T Management
Station via this method.
Removing a Station from the Ring
When you use the Remove radio button, the MicroMMAC-T sends a Remove
MAC Frame to the selected station. Upon receiving this frame, the station will
perform a loopback test to verify that its MAC adapter is functioning correctly.
If the station fails the loopback test, it will stay off the ring. If it passes the test, its
actions will depend on the adapter’s manufacturer. Cabletron DNI cards (and
some others) will reinsert into the ring automatically. IBM adapters (and others)
will remove themselves from the ring until the station is re-booted.
Note that you cannot remove the MicroMMAC-T Management Station from the
ring.
To remove a station from the monitored ring:
1. Click on the Remove radio button in the lower left of the window.
2. Double-click on the station which you want to remove from the ring. The
station will be highlighted to show it is selected. The selected station will be
removed from the ring network, and the port will switch to Link condition.
Setting Station Alarms
Using the Alarm Limits radio button you can invoke the Station Alarm Limits
window, where you can configure and set alarms that will notify your
management station of specified levels of errors reported by individual stations
on your ring network.
