RMON Ethernet History Statistics
Item Description
Index
The index that uniquely identifies the entry in the History Control
Configuration table.
Sample Index
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.
Interval Start The time when the polling (sampling) interval started.
Drop Events
The number of events during the sampling interval in which packets
were dropped on the interface because of lack of resources. This
number does not specify the number of packets that were dropped
but the number of times the packets were dropped.
Octets
The number of data octets (including those in bad packets) received
on the interface (excluding framing bits, but including FCS octets)
during the sampling interval.
Packets
The number of packets received on the interface (including bad
packets, broadcast packets, and multicast packets) during the
sampling interval.
Broadcast Packets
The number of broadcast packets received on the interface during
the sampling interval. These packets were directed to the broadcast
addresses.
Multicast Packets
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 packets addressed to a
broadcast addresses.)
CRC Errors
The number of packets received on the interface during the
sampling interval that have a length (excluding framing bits, but
including FCS octets) of between 64 and 1518 octets. That had
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).
Under Size Packets
The number of packets received on the interface during the
sampling interval that were less than 64 octets in length (excluding
framing bits, but including FCS octets) and that were well formed.
Over Size Packets
The number of packets received on the interface during the
sampling interval that were more than 1518 octets in length
(excluding framing bits, but including FCS octets) and that were well
formed.
