The Station List and Station Map
The Station Command Menu
You can also use the mouse to bring up a command menu, which will allow you
to access Statistics or Timer Statistics specific to the selected station, as well as
remove the station from the ring, and invoke the Station Alarm Limits window.
If you double-click the left mouse button with the cursor positioned over the
desired station, the pop-up command menu will appear with the following
options.
Statistics
Click on this option to bring up the Station Statistics window if a ring station is
selected, or the TR Mgmt Station Statistics window if the MicroMMAC-T
Management Station is selected. Refer to the Token Ring Statistics chapter for
information on these windows.
Timer Statistics
Click on this option to bring up the Station Timer Statistics Window if a ring
station is selected, or the Timer Statistics window for the MicroMMAC-T's
onboard management station, if it is selected. Refer to the Token Ring Statistics
chapter for information on these windows.
Remove
Click on this option to remove the selected station from the ring so that it can
perform a loopback test. When you click this 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 manufacturer of the adapter card. Cabletron 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.
Note that you cannot remove the MicroMMAC-T Management Station from the
ring, so this option is grayed-out when the MicroMMAC-T is selected.
Alarm Limits
Click this selection to bring up the Station Alarm Limits window to set alarms at
individual ring stations. Refer to the Token Ring Alarms chapter for full
information on setting station alarm limits.
Performance Graph
Click this selection to invoke the Station Port Performance Graph, which allows
you to visually track the performance of the selected station. Refer to the Token
Ring Statistics chapter for details on the Station Port Performance Graph.
