Interface Performance Statistics/Bar Graphs
The statistical values (and, where available, the accompanying bar graphs) to the
right of the interface description fields provide a quick summary of interface
performance. You canselect the statisticalvalue youwant to display andthe units
in which you want those values displayed by using the two menu fields directly
above the interface display area, as follows:
1. In the right-most menu field, click on the down arrow and select the unit in
which you wish to display the selected statistic: Load, Raw Counts, or Rate.
2. Once you have selected the base unit, click on the down arrow in the left-most
field to specify the statistic you’d like to display. Note that the options available
from this menu will vary depending on the base unit you have selected.
After youselect a new display mode,the statistics (and graphs,where applicable)
will refresh to reflect the current choice, as described below.
Raw Counts
The total count of network traffic received or transmitted on the indicated
interface since device counters were last reset. Raw counts are provided for the
following parameters:
In Octets Octets received on the interface, including framing
characters.
In Packets Packets (both unicast and non-unicast) received by the
device interface and delivered to a higher-layer protocol.
In Discards Packets received by the device interface that were
discarded even though no errors prevented them from
being delivered toa higher layerprotocol (e.g.,to free up
buffer space in the device).
In Errors Packets received by the device interface that contained
errors that prevented them from being delivered to a
higher-layer protocol.
In Unknown Packets received by the device interface that were
discarded because of an unknown or unsupported
protocol.
Out Octets Octets transmitted by the interface, including framing
characters.
NOTE
Bar graphs are only available when Load is the selected base unit; if you select Raw
Counts or Rate, the Bar Graph column will be removed from the interface display.
