LAN Interface Card Statistics
Inbound Unknown Protocols The number of packets received via the
interface which were discarded because of an unknown
or unsupported protocol.
Outbound Octets The total number of octets transmitted out of the
interface, including framing characters.
Outbound Unicast Packets The total number of packets that
higher-level protocols requested be transmitted to a
subnetwork-unicast address, including those that were
discarded or not sent.
Outbound Non-Unicast Packets The total number of packets that
higher-level protocols requested be transmitted to a
non-unicast (a subnetwork-broadcast or
subnetwork-multicast) address, including those that
were discarded or not sent.
Outbound Discards The number of outbound packets that were
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.
Outbound Errors The number of outbound packets that could not be
transmitted because of errors.
Outbound Queue Length The length of the output packet queue (in
packets)
RFC 1284 Ethernet-Like Interface Statistics
Index A value that uniquely identiļ¬es an interface to an
Ethernet-like medium.
Alignment Errors A count of frames received on a particular interface
that are not an integral number of octets in length and
do not pass the FCS check.
FCS Errors A count of frames received on a particular interface
that are not an integral number of octets in length and
do not pass the FCS check.
Single Collision Frames A count of successfully transmitted frames on a
particular interface for which transmission is inhibited
by exactly one collision.
