LAN Interface Card Statistics
Chapter 5 49
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 identifies 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.
Multiple Collision Frames A count of successfully transmitted frames on a particular
interface for which transmission is inhibited by more than one collision.
Deferred Transmissions A count of frames for which the first transmission attempt on a
particular interface is delayed because the medium is busy. The count
represented by an instance of this object does not include frames involved in
collisions.
Late Collisions The number of times that a collision is detected on a particular interface
later than 512 bit-times into the transmission of a packet.
Excessive Collisions A couple of frames for which transmission on a particular interface fails
due to excessive collisions.
Internal MAC Transmit Errors A count of frames for which transmission on a particular
interface fails due to an internal MAC sublayer transmit error.
Carrier Sense Errors The number of times that the carrier sense condition was lost or never
asserted when attempting to transmit a frame on a particular interface.
Frames Too Long Account of frames received on a particular interface that exceed the
maximum permitted frame size.
