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 1518 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.
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.
This does not include multicast packets.
Transmit Packets Discarded The total number of outbound packets that were discarded even though no
errors were detected that would prevent the packets from being delivered to a
higher-layer protocol.
A possible reason for discarding a packet could be to free up buffer space.
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 buf
fer 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 had 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 dif
ferent 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).
