Table 14-4 Ethernet Threshold Variables (MIBs)
Variable Definition
iflnOctets Total number of octets received on the interface, including
framing octets
iflnUcastPkts Total number of unicast packets delivered to an appropriate
protocol
ifInMulticastPkts Number of multicast frames received error free (not supported by
E-Series)
ifInBroadcastPkts Number of packets, delivered by this sublayer to a higher
(sub)layer, which were addressed to a broadcast address at this
sublayer (not supported by E-Series)
ifInDiscards Number of inbound packets which were chosen to be discarded
even though no errors had been detected to prevent their being
deliverable to a higher-layer protocol (not supported by
E-Series)
iflnErrors Number of inbound packets discarded because they contain
errors
ifOutOctets Total number of transmitted octets, including framing packets
ifOutUcastPkts Total number of unicast packets requested to transmit to a single
address
ifOutMulticastPkts Number of multicast frames transmitted error free (not supported
by E-Series)
ifOutBroadcastPkts Total number of packets that higher-level protocols requested be
transmitted, and which were addressed to a broadcast address at
this sublayer, including those that were discarded or not sent (not
supported by E-Series)
ifOutDiscards Number of outbound packets which were chosen to be discarded
even though no errors had been detected to prevent their being
transmitted (not supported by E-Series)
dot3statsAlignmentErrors Number of frames with an alignment error, that is, the length is
not an integral number of octets and the frame cannot pass the
Frame Check Sequence (FCS) test
dot3StatsFCSErrors Number of frames with framecheck errors, that is, there is an
integral number of octets, but an incorrect FCS
dot3StatsSingleCollisionFrames Number of successfully transmitted frames that had exactly one
collision
dot3StatsMutlipleCollisionFrame Number of successfully transmitted frames that had multiple
collisions
dot3StatsDeferredTransmissions Number of times the first transmission was delayed because the
medium was busy
dot3StatsExcessiveCollision Number of frames where transmissions failed because of
excessive collisions
dot3StatsLateCollision Number of times that a collision was detected later than 64 octets
into the transmission (also added into collision count)
