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 pre-
venting them from being deliverable to a higher-layer protocol.
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 Frame Check Sequence (FCS) with an inte-
gral 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 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 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 over-
loaded with incoming packets, and could not keep up with the inflow.
Received Packets not forwarded
Total - A count of valid frames received which were discarded (i.e. fil-
tered) by the forwarding process.
Local Traffic Frames - The total number of frames dropped in the for-
warding process because the destination address was located off of this
port.
802.3x Pause Frames Received - A count of MAC Control frames
received on this interface with an opcode indicating the PAUSE opera-
tion. This counter does not increment when the interface is operating in
half-duplex mode.
Unacceptable Frame Type - The number of frames discarded from this
port due to being an unacceptable frame type.
