threshold, choose etherStatsCollisions from the Variable menu.
Table 9-15 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
ifInBroadcastPkts The number of packets, delivered by this sub-layer to a higher
(sub-)layer, which were addressed to a broadcast address at this
sub-layer
ifInDiscards The 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
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
ifOutBroadcastPkts The total number of packets that higher-level protocols requested
be transmitted, and which were addressed to a broadcast address
at this sub-layer, including those that were discarded or not sent
ifOutDiscards The number of outbound packets which were chosen to be
discarded even though no errors had been detectedto prevent
their being transmitted
dot3statsAlignmentErrors Number of frames with an alignment error, i.e., 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, i.e., there is an
integral number of octets, but an incorrect Frame Check
Sequence (FCS)
dot3StatsSingleCollisionFrames Number of successfully transmitted frames that had exactly one
collision
dot3StatsMutlipleCollisionFrame Number of successfully transmitted frames that had multiple
collisions
