Parameter Description
Transmitted Errors The number of outbound packets that could not be transmitted
because of errors.
Received Unicast Packets The number of subnetwork-unicast packets delivered to a higher-
layer protocol.
Transmitted Unicast The total number of packets that higher-level protocols requested
Packets be transmitted to a subnetwork-unicast address, including those
that were discarded or not sent.
Received Discarded The number of inbound packets which were chosen to be
Packets 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.
Transmitted Discarded The number of outbound packets which were chosen to be
Packets 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.
Received Multicast The number of packets, delivered by this sub-layer to a higher
Packets (sub-)layer, which were addressed to a multicast address at this
sub-layer.
Transmitted Multicast The total number of packets that higher-level protocols requested
Packets be transmitted, and which were addressed to a multicast address
at this sub-layer, including those that were discarded or not sent.
Received Broadcast The number of packets, delivered by this sub-layer to a higher
Packets (sub-)layer, which were addressed to a broadcast address at this
sub-layer.
Transmitted Broadcast The total number of packets that higher-level protocols requested
Packets be transmitted, and which were addressed to a broadcast address
at this sub-layer, including those that were discarded or not sent.
Received Unknown The number of packets received via the interface which were
Packets discarded because of an unknown or unsupported protocol.
Etherlike Statistics
Single Collision Frames The number of successfully transmitted frames for which
transmission is inhibited by exactly one collision.
Multiple Collision Frames A count of successfully transmitted frames for which transmission
is inhibited by more than one collision.
Late Collisions The number of times that a collision is detected later than 512 bit-
times into the transmission of a packet.
Excessive Collisions A count of frames for which transmission on a particular interface
fails due to excessive collisions. This counter does not increment
when the interface is operating in full-duplex mode.
Deferred Transmissions A count of frames for which the first transmission attempt on a
particular interface is delayed because the medium was busy.
Frames Too Long A count of frames received on a particular interface that exceed
the maximum permitted frame size.
Alignment Errors The number of alignment errors (missynchronized data packets).
FCS Errors A count of frames received on a particular interface that are an
integral number of octets in length but do not pass the FCS check.
This count does not include frames received with frame-too-long
or frame-too-short error.
SQE Test Errors A count of times that the SQE TEST ERROR message is generated
by the PLS sublayer for a particular interface.
Carrier Sense Errors The number of times that the carrier sense condition was lost or
never asserted when attempting to transmit a frame.
