Token Ring Statistics

A.C. Errors

The count detected by the management station of frames (Protocol Data Units or PDUs) containing errors in the A or C bits.

Abort Sequences

The management station’s count of abort sequences detected on the ring, which were issued by ring stations during transmission.

Internal Errors

The number of recoverable internal errors detected by the management station, indicating a ring station in marginal operating condition.

Lost Frames

The number of frames detected by the management station that were transmitted on the ring, but did not return to the transmitting station because the Timer Return to Repeat (TRR) timer expired.

Congestion Errors

The number of times the management station has not been able to copy a PDU addressed to it because of a lack of internal buffering.

FC Errors

The management station’s count of PDU detected on the ring with the A bits already set to 1, which indicates a possible electrical line disturbance, or a duplicate address on the ring.

Token Errors

The number of times the ring’s active monitor detected an error that required the transmission of a token.

Frequency Errors

The number of times that the management station has detected that the incoming frequency differs from the expected frequency by more than allowed.

Soft Errors

The total number of soft errors the management station has detected.

Hard Errors Fields

If a particular type of hard error is detected by the management station, “Detected” will be displayed in the appropriate hard error field. If no hard errors are detected, the field will display “None.”

Signals Lost

These errors occur if the management station has detected a loss of signal condition, which can be the result of a broken ring, a faulty wiring concentrator, or a receiver or transmitter malfunction.
