Description
The total number of packets received that were less than 64 octets long
(excluding framing bits but including FCS octets) and were otherwise well
formed.
The total number of packets received that were more than 1518 octets long
(excluding framing bits but including FCS octets) and were otherwise well
formed.
The total number of packets received that were less than 64 octets long
(excluding framing bits but including FCS octets) and had either a bad Frame
Check Sequence (FCS) with an integral number of octets (FCS Error) or a bad
FCS with a nonintegral number of octets (Alignment Error). It is entirely normal
for etherStatsFragments to increment because it counts both runts (which are
normal occurrences due to collisions) and noise hits.
The best estimate of the total number of collisions on this Ethernet segment.
The total count since the statistics tab was first opened. The elapsed time for the
cumulative counter is displayed at the bottom of the graph dialog box.
The cumulative count divided by the cumulative elapsed time.
The minimum average for the counter for a given polling interval over the
cumulative elapsed time.
The maximum average for the counter for a given polling interval over the
cumulative elapsed time.
The average for the counter over the last polling interval.
If you haven't already done so, enable RMON by choosing RMON > Options
from the Device Manager menu bar.
Right click on the port you want to graph.
Select Enable Rmon History.
From the Device Manager menu bar, choose Graph > Port.
