	TABLE 55	Export configuration and statistics (Continued)
	Parameter		Definition
	CRC alignment errors		The total number of packets received that were from 64 – 1518 octets long, but had
			either a bad FCS with an integral number of octets (FCS Error) or a bad FCS with a
			non-integral number of octets (Alignment Error).
			The packet length does not include framing bits but does include FCS octets.
	Undersize pkts		The total number of packets received that were less than 64 octets long and were
			otherwise well formed.
			This number does not include framing bits but does include FCS octets.
	Fragments		The total number of packets received that were less than 64 octets long and had either
			a bad FCS with an integral number of octets (FCS Error) or a bad FCS with a
			non-integral number of octets (Alignment Error).
			It is normal for this counter to increment, since it counts both runts (which are normal
			occurrences due to collisions) and noise hits.
			This number does not include framing bits but does include FCS octets.
	Oversize packets		The total number of packets received that were longer than 1518 octets and were
			otherwise well formed.
			This number does not include framing bits but does include FCS octets.
			NOTE: 48GC modules do not support count information on oversized packets and
			report 0.
	Jabbers		The total number of packets received that were longer than 1518 octets and had either
			a bad FCS with an integral number of octets (FCS Error) or a bad FCS with a
			non-integral number of octets (Alignment Error).
			NOTE: This definition of jabber is different from the definition in IEEE-802.3 section
			8.2.1.5 (10BASE5) and section 10.3.1.4 (10BASE2). These documents define
			jabber as the condition where any packet exceeds 20 ms. The allowed range to
			detect jabber is between 20 ms and 150 ms.
			This number does not include framing bits but does include FCS octets.
			NOTE: 48GC modules do not support count information on jabbers and report 0.
	Collisions		The best estimate of the total number of collisions on this Ethernet segment.
	64 octets pkts		The total number of packets received that were 64 octets long.
			This number includes bad packets.
			This number does not include framing bits but does include FCS octets.
	65 to 127 octets pkts		The total number of packets received that were 65 – 127 octets long.
			This number includes bad packets.
			This number does not include framing bits but does include FCS octets.
	128 to 255 octets pkts		The total number of packets received that were 128 – 255 octets long.
			This number includes bad packets.
			This number does not include framing bits but does include FCS octets.
	256 to 511 octets pkts		The total number of packets received that were 256 – 511 octets long.
			This number includes bad packets.
			This number does not include framing bits but does include FCS octets.
	512 to 1023 octets pkts		The total number of packets received that were 512 – 1023 octets long.
			This number includes bad packets.
			This number does not include framing bits but does include FCS octets.
	1024 to 1518 octets		The total number of packets received that were 1024 – 1518 octets long.
	pkts		This number includes bad packets.
			This number does not include framing bits but does include FCS octets.
