				The IXF1104 has two
				counters for receive
				and transmit that use
		RxOctetsTotalOK		different naming
	Counter	RxOctetsBad		conventions for the
etherStatsOctets			Counter 32	total Octets and
	32	OctetsTransmittedOK
				Octets Bad. These
		OctetsTransmittedBad		counters must be
				combined to meet
				the RMON definition
				for this statistic.
				The IXF1104 has
		RxUCPkts/TxUCPkts		three counters for the
				etherStatsPkts that
etherStatsPkts	Counter32	RxBCPkts/TxBCPkts	Counter 32	must be combined to
		RxMCPkts/TxMCPkts		give the total packets
				as defined by the
				RMON specification.
etherStatsBroadcastPkts	Counter32	RxBCPkts/TxBCPkts	Counter 32	Same as RMON
				specification
etherStatsMulticastPkts	Counter32	RxMCPkts/TxMCPkts	Counter 32	See table note 2
				The IXF1104 has two
				counters for the
		RxAlignErrors		alignment and CRC
				errors for the RX side
etherStatsCRCAlignErrors	Counter32	RxFCSErrors	Counter 32
				only.
		TxCRCError		The IXF1104 has a
				CRC Error counter
				for the TX side.
		RxRuntErrors		The IXF1104 has two
etherStatsUndersizedPkts	Counter32	RxShortErrors	Counter 32	counters, one for
		Rx Statistics ONLY		Runt errors and one
				for ShortErrors.
etherStatsOversizePkts	Counter32	RxLongErrors	Counter 32	Same as RMON
		TxExcessiveLength Drop		specification

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.
