Bridging

A. C. Errors

The A. C. Errors Þeld displays the number of A. C. errors detected by the selected port. These errors count protocol data units (PDUs) that contain errors in the A or C bits.

Abort Sequences

The Abort Sequences Þeld displays the number of abort sequences transmitted by the selected port.

Internal Errors

The Internal Errors Þeld displays the number of recoverable internal errors detected by the selected port.

Lost Frames

The Lost Frames Þeld displays the number of lost frames transmitted by the selected port that have not returned because the Timer Return to Repeat (TRR) expired.

Congestion Errors

The Congestion Errors Þeld displays the number of times the selected port has not been able to copy a protocol data unit (PDU) addressed to it because of a lack of internal buffering.

F. C. Errors

The F. C. Errors Þeld displays the number of protocol data units (PDUs) addressed to the selected station with the A bits already set to 1. This error indicates that a possible electrical line disturbance or a duplicate address has occurred on the ring.

Token Errors

The Token Errors Þeld displays the number of times that the selected station, acting as the active monitor, detected an error condition that needed a token transmitted.

Soft Errors

The Soft Errors Þeld displays the number of soft errors detected by the selected port.

Hard Errors

The Hard Errors Þeld displays the number of immediately recoverable fatal errors detected by the selected port.

Signal Loss

The Signal Loss Þeld displays the number of times that the selected port has detected the loss of a signal condition from the ring.
