Statistics
The selected interface number and its description are displayed at the top of the
Statistics window. The column on the left side of the window displays each
statistic’s name, total count, and percentage; the column on the right displays the
peak value for each statistic, and the date and time that peak occurred. Note that
peak values are always Delta values; see
Viewing Total, Delta, and Accumulated
, on
, for more information.
The Ethernet statistics are as follows:
Bytes
Displays the total number of bytes contained in packets processed on the network
segment. This number includes bytes contained in error packets.
Packets
Displays the total number of packets processed on the network segment. Again,
this number includes error packets.
Drop Events
This field indicates the number of times packets were dropped because the device
could not keep up with the flow of traffic on the network. Note that this value
does not reflect the number of packets dropped, but only the number of times
packets were dropped.
% Load
Displays the network segment load during the sample interval, in hundredths of
a percent; this percentage reflects the network segment load compared to the
theoretical maximum load (10/100 Mbps) of an Ethernet network.
Packet Type
Multicast
Indicates the number of good packets processed on the network
segment that were destined for more than one address. Note that
this total does not include broadcast packets.
Broadcast
Indicates the number of good packets processed on the network
segment that had the broadcast (FF-FF-FF-FF-FF-FF) destination
address.
Unicast
Indicates the number of good packets processed on the network
segment that were destined for a single address.
The percentages displayed to the right of the numerical values for these fields
indicate what percentage of good packets transmitted on the network segment
were multicast, broadcast, and unicast; these percentages will add up to 100. The
pie chart in the center of the window provides a graphical view of the percentage
breakdown; colors in the pie chart correspond to colors in the percentage display
boxes. Values listed to the right of the pie chart indicate peak delta values
recorded since the statistics screen was launched, and the date and time they
occurred.
