Field Description
SampleIndex Indicates the sample number. As history samples are taken,
they are assigned greater sample numbers
Utilization Estimates the percentage of a link’s capacity that was used
during the sampling interval.
Octets The number of octets received on the link during the
sampling period.
Pkts The number of packets received on the link during the
sampling period.
BroadcastPkts The number of packets received on the link during the
sampling interval that destined for the packet address.
MulticastPkts The number of packets received on the link during the
sampling interval that are destined for the multicast address.
This doe not include the broadcast packets.
DropEvents The number of received packets that were dropped due to
system resource constraints.
CRCAlignErrors The number of packets received during a sampling interval
that were between 64 and 1518 octets long. This length
included Frame Check Sequence (FCS) octets but not
framing bits. The packets had a bad FCS with either an
integral number of octects (FCS Error), or a non-integral
number of octets (Alignment Error).
UndersizePkts The number of packets received during the sampling interval
were less than 64 octets long (including FCS octets, but not
framing bits.
OversizePkts The number of packets received during the sampling interval
were longer than 1518 octets (including FCS octets, but not
framing bits, and were otherwise well formed.
Fragments The number of packets received during the sampling interval
were less than 64 octets long (including FCS octets, but not
framing bits. The packets had a bad FCS with either an
integral number of octects (FCS Error), or a non-integral
number of octets (Alignment Error).
Collisions The best estimate of the number of collisions on an Ethernet
segment during a sampling interval.
