ASAP Ethernet Statistics Parameters (continued)
Meaning
The total number of packets (including bad packets) received
that were between 256 and 511 bytes in length inclusive
(excluding framing bits but including FCS bytes).
The total number of packets (including bad packets) received
that were between 512 and 1023 bytes in length inclusive
(excluding framing bits but including FCS bytes).
The total number of packets (including bad packets) received
that were between 1024 and 1518 bytes in length inclusive
(excluding framing bits but including FCS bytes).
The number of inbound packets which were chosen to be
discarded even though no errors had been detected to prevent
their being deliverable to a higher-layer protocol. One possible
reason for discarding such a packet could be to free up buffer
space.
The number of outbound packets which were chosen to be
discarded even though no errors had been detected to prevent
their being transmitted. One possible reason for discarding such
a packet could be to free up buffer space.
The number of inbound packets (or transmission units) that
contained errors preventing them from being deliverable to a
higher-layer protocol.
A count of frames received on a particular interface that exceed
the maximum permitted frame size.
The total number of packets (including bad packets, broadcast
packets, and multicast packets) received.
The number of outbound packets (or transmission units) that
could not be transmitted because of errors.
A count of frames for which reception on a particular interface
fails due to an internal MAC sublayer receive error. A frame is
only counted by an instance of this object if it is not counted by
the corresponding instance of either the
dot3StatsFrameTooLongs object, the
dot3StatsAlignmentErrors object, or the dot3StatsFCSErrors
object. The precise meaning of the count represented by an
instance of this object is implementation-specific. In particular,
an instance of this object may represent a count of receive
errors on a particular interface that are not otherwise counted.
