Description
The total number of good packets received that were directed to a multicast
address. This number does not include packets directed to the broadcast
address.
address. This does not include multicast packets.
The number of inbound packets that were discarded even though no errors were
detected to prevent their being delivered to a higher-layer protocol. A possible
reason for discarding a packet could be to free up buffer space.
The total number of inbound packets that contained errors preventing them from
being deliverable to a higher-layer protocol.
The total number of packets received that were longer than 1518 octets
(excluding framing bits, but including FCS octets), and included either a bad
frame check sequence (FCS) with an integral number of octets (FCS Error) or a
bad FCS with a nonintegral number of octets (alignment error). This definition of
jabber is different from 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.
The total number of packets received that were less than 64 octets in length with
ERROR CRC (excluding framing bits but including FCS octets).
The total number of packets received that were less than 64 octets in length with
GOOD CRC (excluding framing bits but including FCS octets).
The total number of packets received with a length (excluding framing bits, but
including FCS octets) of between 64 and 1518 octets, inclusive, but included a
bad frame check sequence (FCS) with a nonintegral number of octets.
The total number of packets received with a length (excluding framing bits, but
including FCS octets) of between 64 and 1518 octets, inclusive, but included a
bad frame check sequence (FCS) with an integral number of octets.
The total number of frames discarded because this port was overloaded with
incoming packets, and could not keep up with the inflow.
A count of MAC control frames received on this interface with an opcode
indicating the PAUSE operation. This counter does not increment when the
interface is operating in half-duplex mode.
The number of frames discarded from this port due to being an unacceptable
frame type.
The total number of octets of data (including those in bad packets) transmitted
on the network (excluding framing bits but including FCS octets). This object can
be used as a reasonable estimate of Ethernet utilization. If greater precision is
desired, the etherStatsPkts and etherStatsOctets objects must be sampled
before and after a common interval.
The total number of packets (including bad packets) received that were 64
octets in length (excluding framing bits but including FCS octets).
