interval for an interface on the device.
History Indexes can include: 100 Mbps segment with samples
taken every 30 seconds, 100 Mbps segment with samples
taken every 1800 seconds, 10 Mbps segment with samples
taken every 30 seconds, or 10 Mbps segment with samples
taken every 1800 seconds.
Refresh Time Interval
Interval at which data displayed to the screen is refreshed.
Sample Index
An index that uniquely identifies the particular sample this entry
represents among all samples associated with the same history
control entry. This index starts at 1 and increases by one as
each new sample is taken.
Interval Start
Value of sysUpTime at the start of the interval over which this
sample was measured.
Drop Events
Total number of events in which packets were dropped by the
probe due to lack of resources during this sampling interval.
This number is not necessarily the number of packets dropped,
it is just the number of times this condition has been detected.
Octets
Total number of octets of data (including those in bad packets)
received on the network (excluding framing bits but including
FCS octets).
Packets

that were directed to the broadcast address.

include packets addressed to the broadcast address.
