Removing a Station from the Ring

The Remove Station option on the Station Port menu allows you to remove a station from the ring so that it can perform a loopback test. When you select this option, the TRMMIM 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 manufacturer of the adapter card. Cabletron Token Ring DNI® cards (and some others) will reinsert into the ring automatically. IBM® adapter cards (and others) will remove themselves from the ring until the station is re-booted.

To remove a station:

1.Click mouse button 3 in the Port Index or Port Status box to display the Station Port menu.

2.Drag down to Remove Station and release.
