Term Definition
Packets Received • Total Packets Received Without Error - The total number of packets received that were without
Successfully 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.
Packets Received • Total - The total number of inbound packets that contained errors preventing them from being
with MAC Errors 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 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 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 overloaded with incoming
packets, and could not keep up with the inflow.
Total Ignored The total number of dropped packets including those that were aborted.
Frames
Total Deferred The total number of frames that could not be transmitted after multiple attempts because they
Frames encountered collisions.
