INTEL 82557 FAST ETHERNET PCI BUS CONTROLLER

Table 10. Statistical Counters (Contd.)
44
Receive Alignment Errors
This counter contains the number of frames that are both
misaligned (i.e., where CRS deasserts on a nonoctal boundary) and
contain a CRC error. The counter is updated, if needed, regardless
of the RU state. The ALNERRS counter is mutually exclusive to
the CRCERRS and SHRTFRM counters.
48
Receive Resource Errors
This counter contains the number of good frames discarded
because there were no resources available. Frames intended for a
host whose RU is in the No Resources state fall into this category.
If the 82557 is configured to Save Bad Frames and the status of
the received frame indicates that it is a bad frame, the RSCERRS
counter is not updated.
52
Receive Overrun Errors
This counter contains the number of frames known to be lost
because the local system bus was not available. If the traffic
problem persists for more than one frame, the frames that follow
the first are also lost; however, because there is no lost frame
indicator, they are not counted.
56
Receive Collision Detect (CDT)
Errors
This counter contains the number of frames that encountered
collisions during frame reception.
60
Receive Short Frame Errors
This counter contains the number of received frames that are
shorter than the minimum frame length.
The SHRTFRM counter is
mutually exclusive to the ALNERRS and CRCERRS counters and
has a higher priority (i.e., a short frame will always increment only
the SHRTFRM counter).
64
Dump Counters Completion
Status
The Statistical Counters are initially set to zero by
the 82557 after reset. They cannot be preset to
anything other than zero. The 82557 increments the
counters by internally reading them, incrementing
them
and
writing them back. This process is invisible to the
CPU and PCI bus. Refer to the
82557 User’s Manual
for additional information.
