Displaying Port Status
•RX_Q Overflows - number of incoming packets dropped by the port due to a lack of buffers. This entry shows status only; it is not selectable. After a reboot, the ATX tries to automatically re-allocate the Small Buffers among the ports so that the total number of RX_Q Overflows is minimized.
•Ring State - either opened, closed, or ring failure. This entry shows status only; it is not selectable.
•Ring Status - normally No Problems Detected. This entry shows status only; it is not selectable. If there are ring problems, one of the following will be displayed:
-Ring Recovery - This could be a normal state, indicating that a new station has just inserted into the ring and temporarily broken it. The ring should be back to normal in seconds. If it is not, check for stuck relays on a passive MAU, DB9 connectors plugged into the video port, mismatched ring speed (some stations at 4, some at 16), or poor wiring or connections.
-Single Station - The module’s Token Ring port is the only station it sees on the ring.
-Auto Removal - There is a serious problem with the connection, which resulted in the Token Ring port removing itself from the ring. Check the conditions listed under Ring Recovery.
-Lobe Wire Fault - The cable between the ATX and the MAU is defective causing the loopback test to fail. Therefore, the Token Ring port isn’t inserted into the ring.
-Soft Error - Historically indicates that an error has occurred. This can be caused by inserting a new station into the ring. Since this value represents a historical set, it may not necessarily indicate a current error condition.
-Hard Error - This frequently occurs when a new station is inserted into the ring; it can be ignored.
-Transmitting Beaconing - As state similar to Ring Recovery. Follow the guidelines above.
-Signal Loss - The Token Ring port is unable to communicate with the ring.
