The RMON - Ether History Table window displays data for a selected
interface.
Index |
Integer that uniquely identifies a row in
the history table. |
Sample
Index |
Integer that uniquely identifies the
particular sample this entry represents among all samples associated with the same row of
the history table. This index starts at 1 and increases by one as each new sample is
taken. |
Interval
Start |
Value of sysUpTime (in the mib-II system
group) at the start of the interval over which this sample was measured. All of the
following fields are counters for statistics gathered during the corresponding sampling
interval. |
Drop
Events |
Number of events in which packets were
dropped by the monitor due to lack of resources. This is not necessarily the actual
count of packets dropped, but the number of times this condition has been detected. |
Octets |
Number of received octets of data
(including those in bad packets). |
Pkts |
Total number of packets received, including
bad packets, broadcast packets, and multicast packets. |
Broadcast
Pkts |
Number of good broadcast packets received. |
Multicast
Pkts |
Number of good multicast packets received. |
CRC
Align Errors |
Number of packets received of the proper
size (between 64 and 1,518 octets), but with either a CRC error or an alignment error (not
an integral number of octets). |
Undersize
Pkts |
Number of packets received that were well
formed but less than 64 octets long. |
Oversize
Pkts |
Number of packets received that were less
well formed but greater than 1,518 octets long. |
Fragments |
Number of packets received that were less
than 64 octets long and with either a CRC error or an alignment error (not an integral
number of octets). |
Jabbers |
Number of packets received that were
greater than 1,518 octets long and with either a CRC error or an alignment error (not an
integral number of octets). |
Collisions |
Best estimate of the total number of
collisions. |
Utilization |
Ratio between the total number of bits that
were actually transmitted to the number of bits that could have been transmitted. |
