Table 22-5 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 (G-Series, CE-Series, and ML-Series only.) Number of multicast
frames received error free
ifInBroadcastPkts (G-Series, CE-Series, and ML-Series only.) The number of
packets, delivered by this sublayer to a higher (sub)layer, that
were addressed to a broadcast address at this sublayer
ifInDiscards (G-Series, CE-Series, and ML-Series only.) The number of
inbound packets that were chosen to be discarded even though no
errors had been detected to prevent their being deliverable to a
higher-layer protocol
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 (G-Series, CE-Series, and ML-Series only.) Number of multicast
frames transmitted error free
ifOutBroadcastPkts (G-Series, CE-Series, and ML-Series only.) The total number of
packets that higher-level protocols requested be transmitted, and
that were addressed to a broadcast address at this sublayer,
including those that were discarded or not sent
ifOutDiscards (G-Series only) The number of outbound packets that were
chosen to be discarded even though no errors had been detected
to prevent their being transmitted
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 frame check errors, that is, there is an
integral number of octets, but an incorrect FCS
dot3StatsSingleCollisionFrames (Not supported by E-Series or G-Series.) Number of successfully
transmitted frames that had exactly one collision
dot3StatsMutlipleCollisionFrames (Not supported by E-Series or G-Series.) Number of successfully
transmitted frames that had multiple collisions
dot3StatsDeferredTransmissions (Not supported by E-Series or G-Series.) Number of times the
first transmission was delayed because the medium was busy
dot3StatsLateCollisions (Not supported by E-Series or G-Series.) Number of times that a
collision was detected later than 64 octets into the transmission
(also added into collision count)
