•
Broadcast Packets Received – Indicates the total number of
received good packets that were directed to the broadcast
address.
Indicates the number of inbound packets that were selected for discard
even though no errors preventing their delivery to a higher-layer protocol
had been detected. One potential reason for discarding such packets
would be to free up buffer space.
•
Total Packets Received with MAC Errors – Indicates the total
number of inbound packets containing errors that prevented
them from being delivered to a higher-layer protocol.
•
Jabbers Received – Indicates the number of received packets
that were longer than 1518 octets (excluding framing bits, but
including FCS octets), and had either a bad FCS with a non-
integral number of octets (Alignment Error) or a bad Frame
Check Sequence (FCS) with an integral number of octets (FCS
Error). It should be noted that this definition of a jabber is
different than that provided in IEEE-802.3 section 8.2.1.5
(10BASE5) and section 10.3.1.4 (10BASE2). These documents
define a jabber as any packet exceeding 20 ms. The allowed
range for detecting a jabber is between 20 ms and 150 ms.
•
Fragments/Undersize Received – Indicates the total number
of received packets that were less than 64 octets in length
(excluding framing bits but including FCS octets).
•
Alignment Errors – – Indicates the total number of received
packets that had a length (excluding framing bits, but including
FCS octets) of between 64 and 1518 octets inclusive, but that
also had a bad Frame Check Sequence (FCS) with a non-
integral number of octets.
•
FCS Errors – – Indicates the total number of received packets
that had a length (excluding framing bits, but including FCS
octets) of between 64 and 1518 octets inclusive, but that also
had a bad Frame Check Sequence (FCS) with an integral
number of octets.
•
Overruns – Indicates the total number of frames that were
discarded as this port was overloaded with incoming packets,
such that it could not keep up with the inflow.
•
Total Received Packets Not Forwarded – Indicates the count
of valid received frames that were discarded (that is, filtered) by
the forwarding process.
•
802.3x Pause Frames Received – Indicates the count of MAC
Control frames with an opcode indicating the PAUSE operation
that were received on this interface. This count does not change
when the interface is operating in half-duplex mode.
•
Unacceptable Frame Type – Indicates the number of frames
discarded from this port because they were of an unacceptable
frame type.
•
Total Packets Transmitted (Octets) – Indicates the total
number of octets of data received on the network (excluding
framing bits but including FCS octets and those in bad packets).
This parameter provides a reasonable estimate of Ethernet
utilization. If the user requires greater precision, the
etherStatsOctets and etherStatsPkts objects should be sampled
