Table 47 Ethernet statistics for port Statistics dot3StatsFrameTooLongs dot3StatsInternalMacReceiveErrors Description 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. 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.

Description
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.

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.
Errors—IfHCIn
For packet-oriented interfaces, the number of inbound packets that contained errors
preventing them from being delivered to a higher-layer protocol.
For character-oriented or fixed-length interfaces, the number of inbound transmission
units that contained errors preventing them from being deliverable to a higher-layer
protocol.
Octets—IfHCOut
The total number of octets transmitted out of the interface, including framing
characters.
