Field Name Field Description
MAC statistics Receive
the following:
Total octets
Gigabit Ethernet IQ PICs, the received octets count varies by interface type.
For more information, see
Unicast packets, Broadcast packets,
broadcast, and multicast packets.
CRC/Align errors
(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
If this value is ever nonzero, the PIC or a cable is probably malfunctioning.
MAC control frames
MAC pause frames
code.
Oversized frames
Jabber frames
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
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.
VLAN tagged frames
uses the TPID of 0x8100 in the frame to determine whether a frame is tagged
or not.
Code violations
reception error" or "invalid data symbol error."
