Command Line Interface 49
Table 37 Ethernet statistics for port
Statistics Description
dot3StatsInternalMacTransmitErrors A count of frames for which transmission on a particular
interface fails due to an internal MAC sublayer transmit error.
A frame is only counted by an instance of this object if it is not
counted by the corresponding instance of either the
dot3StatsLateCollisions object, the
dot3StatsExcessiveCollisions object, or the
dot3StatsCarrierSenseErrors 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 transmission
errors on a particular interface that are not otherwise counted.
dot3StatsFrameTooLongs A count of frames received on a particular interface that
exceeds the maximum permitted frame size.
The count represented by an instance of this object is
incremented when the frameTooLong status is returned by the
MAC service to the LLC (or other MAC user).
Received frames for which multiple error conditions obtained
are, according to the conventions of IEEE 802.3 Layer
Management, counted exclusively according to the error status
presented to the LLC.
dot3StatsInternalMacReceiveErrors 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 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 received errors
on a particular interface that are not otherwise counted.

Table 38 Interface statistics for port
Statistics Description
Octets—IfHCIn The total number of octets received on the interface, including framing characters.
UcastPkts—IfHCIn The number of packets, delivered by this sublayer to a higher sublayer, which were
not addressed to a multicast or broadcast address at this sublayer.
BroadcastPkts—IfHCIn The number of packets, delivered by this sublayer to a higher sublayer, which were
addressed to a broadcast address at this sublayer.
MulticastPkts—IfHCIn The total number of packets, delivered by this sublayer. These are the packets that
higher-level protocols requested to be transmitted, and which were addressed to a
multicast address at this sublayer, including those that were discarded or not sent.
For a MAC layer protocol, this includes both group and functional addresses.
Discards—IfHCIn The number of inbound packets which were chosen to be discarded even though no
errors were detected to prevent their being delivered to a higher-layer protocol. One
possible reason for discarding such a packet could be to free up buffer space.
