Packets RX and TX 2048-4095 Octets: The total number of packets (including bad packets)
received that were between 2048 and 4095 octets in length inclusive (excluding framing bits but
including FCS octets).
Packets RX and TX 4096-9216 Octets: The total number of packets (including bad packets)
received that were between 4096 and 9216 octets in length inclusive (excluding framing bits but
including FCS octets).
Total Packets Received Without Errors
Unicast Packets Received: The number of subnetwork-unicast packets delivered to a higher-layer
protocol.
Multicast Packets Received: The total number of good packets received that were directed to a
multicast address. Note that this number does not include packets directed to the broadcast address.
Broadcast Packets Received: The total number of good packets received that were directed to the
broadcast address. Note that this does not include multicast packets.
Total Packets Received with MAC Errors
Jabbers Received: The total number of packets received that were longer than 1518 octets
(excluding framing bits, but including FCS 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 that
this definition of jabber is different than 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.
Undersize Received: The total number of packets received that were less than 64 octets in length
with GOOD CRC(excluding framing bits but including FCS octets).
Fragments Received: The total number of packets received that were less than 64 octets in length
with ERROR CRC(excluding framing bits but including FCS octets).
Alignment Errors: The total number of packets received that had a length (excluding framing bits,
but including FCS octets) of between 64 and 1518 octets, inclusive, but had a bad FCS with a
non-integral number of octets.
FCS Errors: The total number of packets received that had a length (excluding framing bits, but
including FCS octets) of between 64 and 1518 octets, inclusive, but had a bad FCS with an integral
number of octets
Overruns: The total number of frames discarded as this port was overloaded with incoming packets,
and could not keep up with the inflow.
Total Packets Transmitted (Octets)
Packets Transmitted 64 Octets: The total number of packets (including bad packets) received that
were 64 octets in length (excluding framing bits but including FCS octets).
Packets Transmitted 65-127 Octets: The total number of packets (including bad packets) received
that were between 65 and 127 octets in length inclusive (excluding framing bits but including FCS
octets).
Packets Transmitted 128-255 Octets: The total number of packets (including bad packets)
received that were between 128 and 255 octets in length inclusive (excluding framing bits but
including FCS octets).
Packets Transmitted 256-511 Octets: The total number of packets (including bad packets)
received that were between 256 and 511 octets in length inclusive (excluding framing bits but
including FCS octets).
