Receive Packets Discarded 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.
Total Packets Received with
MAC Errors
The total number of inbound packets that contained errors preventing
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 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.
Fragments Received The total number of packets received that were less than 64 octets
in
length with
ERROR CRC (excluding framing bits but including FCS octets).
Undersize Received The total number of packets received that were less than 64 octets in
length with
GOOD CRC (excluding framing bits but including FCS octets).
Alignment Errors 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.
Rx FCS Errors 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.
Total Received Packets Not
Forwarded
The number of valid frames received that were discarded (that is,
filtered)
by the
forwarding process.
802.3x Pause Frames
Received
The number of MAC control frames received on the interface with an opcode
indicating the PAUSE operation.
This counter does not increment when the
interface is operating in half-duplex mode.
Total Packets Transmitted
(Octets)
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 yo need greater
precision, the etherStatsPkts and etherStatsOctets objects must be sampled
before and after a common interval.
Packets Transmitted 64
Octets
The total number of packets (including bad packets) received that were 64
octets in length (excluding framing bits but including FCS octets).
Packets Transmitted 65-127
Octets
The total number of packets (including bad packets) received that
were
between
65 and 127 octets in length inclusive (excluding framing bits but including FCS
octets).
Packets Transmitted 128-255
Octets
The total number of packets (including bad packets) received that
were
between
128 and 255 octets in length inclusive (excluding framing bits but including FCS
octets).
