The index that uniquely identifies the entry in the History Control Configuration
table.
An index that uniquely identifies the particular polling sample that this entry
represents among all polling samples associated with the same entry in the
History Control Configuration table. This index starts at 1 and increases by one
as each new polling sample is taken.
The time when the polling (sampling) interval started.
The number of events during the sampling interval in which packets were
dropped on the interface because of the lack of resources. This number does not
specify the number of packets that were dropped but the number of times the
packets were dropped.
The number of data octets (including those in bad packets) received on the
interface (excluding the framing bits, but including the FCS octets) during the
sampling interval.
The number of packets received on the interface (including the bad packets, the
broadcast packets, and the multicast packets) during the sampling interval.
The number of broadcast packets received on the interface during the sampling
interval. These packets were directed to the broadcast addresses.
The number of multicast packets received on the interface during the sampling
interval. These packets were directed to the multicast addresses. (This number
does not include the packets addressed to a broadcast addresses.)
The number of packets which are received on the interface during the sampling
interval, have a length (excluding the framing bits, but including the FCS octets)
between 64 and 1518 octets, and have either a bad frame check sequence
(FCS) with an integral number of octets (FCS error) or a bad FCS with a non
integral number of octets (alignment error).
The number of packets which are received on the interface during the sampling
interval, less than 64 octets in length (excluding the framing bits, but including
the FCS octets), and were well formed.
The number of packets which are received on the interface during the sampling
interval, more than 1518 octets in length (excluding the framing bits, but
including the FCS octets) and that were well formed.
The number of packets which are received on the interface during the sampling
interval, are less than 64 octets in length (excluding the framing bits, but
including the FCS octets), and have either a bad frame check sequence (FCS)
with an integral number of octets (FCS error) or a bad FCS with a non integral
number of octets (alignment error).
The number of packets which are received on the interface during the sampling
interval, are longer than 1518 octets in length (excluding the framing bits, but
including the FCS octets) , and have either a bad frame check sequence (FCS)
with an integral number of octets (FCS error) or a bad FCS with a non integral
number of octets (alignment error).
The best estimate of the number of collisions on the interface during the
sampling interval.
The best estimate of the mean physical layer network utilization on the interface
during the sampling interval, in hundredths of a percent.
