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.
