AC Errors

Number of times a station received an Active Monitor Present (AMP) frame or a Standby Monitor Present (SMP) frame in which both the address recognized (A) bit and the frame copied (C) bit are set to 0, indicating that no station has recognized the destination address and copied the frame, and then receives another SMP frame in which both the address recognized bit and the frame copied bit are set to 0 without first receiving an AMP frame. This condition indicates a station that cannot set the address recognized and the frame copied bits properly.

Abort Transmit Errors

This counter is incremented when a station transmits an abort delimiter while transmitting.

Internal Errors

This counter is incremented when a station recognizes an internal error.

Lost Frame Errors

This counter is incremented when a station is transmitting and its TRR timer expires. This condition denotes a condition where a transmitting station in strip mode does not receive the trailer of the frame before the TRR timer goes off.

Receive Congestion

This counter is incremented when a station recognizes a frame addressed to its specific address, but has no available buffer space indicating that the station is congested.

Frame Copied Errors

This counter is incremented when a station recognizes a frame addressed to its specific address and detects that the FS field A bits are set to 1 indicating a possible line hit or duplicate address.

Token Errors

This counter is incremented when a station acting as the active monitor recognizes an error condition that needs a token transmitted.

Soft Errors

The number of Soft Errors the port has detected. It directly corresponds to the number of Report Error MAC frames that this port has transmitted. Soft Errors are those which are recoverable by the MAC layer protocols.
