The Station List and Station Map

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.
