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.

Packets Received with MAC Errors

Total - The total number of inbound packets that contained errors
preventing them from being deliverable to a higher-layer proto-
col.

Jabbers Received - The total number of packets received that
were longer than 1518 octets (excluding framing bits, but includ-
ing FCS octets), and had either a bad Frame Check Sequence
(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.

Fragments/Undersize Received - The total number of packets
received that were less than 64 octets in length (excluding fram-
ing 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 Frame
Check Sequence (FCS) with a non-integral number of octets.

Rx 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 Frame
Check Sequence (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.

Received Packets not forwarded
