Packets RX and TX > 1518 Octets
- The total number of packets (including bad packets) received
or transmitted that were longer than 1518 octets in length (excluding framing bits but including FCS
octets).
Octets Received
- The total number of octets of data (including those in bad packets) received 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 should be sampled before and after a common interval.
Packets Received 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 Received 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 Received 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).
Packets Received 256-511 Octets
- The total number of packets (including bad packets) received
that were between 256 and 511 octets in length inclusive (excluding framing bits but including FCS
octets).
Packets Received 512-1023 Octets
- The total number of packets (including bad packets) received
that were between 512 and 1023 octets in length inclusive (excluding framing bits but including FCS
octets).
Packets Received 1024-1518 Octets
- The total number of packets (including bad packets)
received that were between 1024 and 1518 octets in length inclusive (excluding framing bits but
including FCS octets).
Packets Received > 1518 Octets
- The total number of packets received that were longer than
1522 octets (excluding framing bits, but including FCS octets) and were otherwise well formed.
Total Packets Received Without Errors
- The total number of packets received that were without
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.
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 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 20ms. The allowed range to detect jabber is
between 20ms and 150ms.
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).
