Term Definition
Receive Packets The number of inbound packets which were chosen to be discarded even though no errors had
been detected to prevent their being deliverable to a higher-layer protocol. One possible
Discarded
reason for discarding such a packet could be to free up buffer space.
Packets Received • Total Packets Received with MAC Errors - The total number of inbound packets that

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 20–150 ms.
