Counter 32
The IXF1104 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
RxMCPkts/TxMCPkts
Counter 32
The IXF1104 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 has two
counters for the
alignment and CRC

only.
The IXF1104 has a
CRC Error counter
for the TX side.

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 support this and increment when either an RX FIFO or TX FIFO overflows. If any IXF1104
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.
