1. R = Read Only; CoR = Clear on Read; W = Write; R/W = Read/Write
2. When sending in large frames, the counters can only deal with certain limits. The behavior of the
LongErrors and VeryLongErrors counters is as follows: VeryLongErrors counts frames that are
2*MaxFrameSize, dependent on where the MaxFrameSize variable is set. If MaxFrameSize sets greater
than half of the available count in RxOctetsBad (2^14-1), VeryLongErrors is never incremented, but
LongErrors is incremented. This is due to a limitation in the counter size, which means that an accurate
count will not occur in the RxOctetsBAD counter if the frame is larger than 2^14-1. MaxFrameSize is
determined by the settings in the

Frames bigger than the maximum allowed, with
both OK CRC and the integral number of octets
Default maximum allowed is 1518 bytes
untagged and 1522 bytes tagged, but the value
can be changed by a register
Frames bigger than the larger of
2*MaxFrameSize and 50000 bits are not
counted here, but counted in the VeryLongError
counter.
Frames bigger than the maximum allowed, with
either a bad CRC or a non-integral number of
octets. The default maximum allowed is 1518
bytes untagged and 1522 bytes tagged, but the
value can be changed by a register.
Frames bigger than the larger of
2*MaxFrameSize and 50000 bits are not
counted here, but counted in the VeryLongError
counter.
Number of Pause MAC control frames received
This statistic register increments on any valid
64byte Pause frame with valid CRC and will also
increment on 64byte Pause Frames with an
invalid CRC if bit 5 of the
Control ($ Port_Index + 0x19)”
Number of MAC control frames received with an
op code different from 0001 (Pause)
Frames bigger than the larger of
2*MaxFrameSize and 50000 bits
The total number of packets received that are
less than 64 octets in length, but longer than or
equal to 96 bit times.
Note: RxRuntErrors is not supported in the
IXF1110. Any runt or short packets received are
not counted in this register.
Note: The “ShortRuntsThreshold” Register
controls the byte count used to determine the
difference between Runts and Shorts, and
therefore controls which counter is incremented
for a given frame size. This counter is only
updated after receipt of two good frames.
