Level of OutputField DescriptionField Name
extensiveReceive and Transmit statistics reported by the PIC's MAC subsystem.
• Total octets and total packets—Total number of octets and packets. For
Gigabit Ethernet IQ PICs, the received octets count varies by interface type.
• Unicast packets, Broadcastpackets, and Multicast packets—Number of unicast,
broadcast, and multicast packets.
• CRC/Align errors—Total number of packets received that had a length
(excluding framing bits, but including FCS octets) of between 64 and 1518
octets, inclusive, and had either a bad FCS with an integral number of octets
(FCS Error) or a bad FCS with a nonintegral number of octets (Alignment
Error).
• FIFO error—Number of FIFO errors reported by the ASIC on the PIC. If this
value is ever nonzero, the PIC is probably malfunctioning.
• MAC control frames—Number of MAC control frames.
• MAC pause frames—Number of MAC control frames with pause operational
code.
• Oversized frames—Number of frames that exceed 1518 octets.
• Jabber frames—Number of frames that were longer than 1518 octets (excluding
framing bits, but including FCS octets), and had either an FCS error or an
alignment error. 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 in which any packet exceeds 20
ms. The allowed range to detect jabber is from 20 ms to 150 ms.
• Fragment frames—Total number of packets that were less than 64 octets in
length (excluding framing bits, but including FCS octets), and had either an
FCS error or an alignment error. Fragment frames normally increment because
both runts (which are normal occurrences caused by collisions) and noise
hits are counted.
• Code violations—Number of times an event caused the PHY to indicate “Data
reception error” or “invalid data symbol error.”
