Counter 32
The IXF1104 MAC
has two counters for
receive and transmit
that use different
naming conventions
for the total Octets
and Octets Bad.
These counters must
be combined to meet
the RMON definition
for this statistic.
etherStatsPkts Counter32
RxUCPkts/TxUCPkts
RxBCPkts/TxBCPkts

Counter 32
The IXF1104 MAC
has three counters
for the etherStatsPkts
that must be
combined to give the
total packets as
defined by the
RMON specification.

Counter 32
The IXF1104 MAC
has two counters for
the alignment and
CRC errors for the
RX side only.
The IXF1104 MAC
has a CRC Error
counter for the TX
side.

Counter 32
The IXF1104 MAC
has two counters,
one for Runt errors
and one for
ShortErrors.
NOTE: The RMON specification requires that this is, “The total number of events where packets were dropped
by the probe due to a lack of resources. This number is not necessarily the number of packets dropped;
it is the number of times this condition is detected." The
“RX FIFO Overflow Frame Drop Counter Ports
0 - 3 ($0x594 – 0x597)" and “TX FIFO Overflow Frame Drop Counter Ports 0 - 3 ($0x621 – 0x624)" in
the IXF1104 MAC support this and increment when either an RX FIFO or TX FIFO overflows. If any
IXF1104 MAC programmable packet filtering is enabled, the
“RX FIFO Errored Frame Drop Counter
Ports 0 - 3 ($0x5A2 - 0x5A5)" and “TX FIFO Errored Frame Drop Counter Ports 0 - 3 ($0x625 – 0x629)"
increment with every frame removed in addition to the existing frames counted due to FIFO overflow.
