Interface Performance Statistics/Bar Graphs

With the statistics and accompanying bar graphs to the right of the interface description ﬁelds, you can view the performance of your device interfaces at one glance.

You can select the attributes of the statistics and graphs by using two menu buttons directly above the graphs. These menu buttons work in conjunction to determine what the statistics or graphs will display, as follows:

1.Click on the right menu button to select the base units to display in the

statistics and graphs: , , or .

2.Once you have selected the base units, click on the left menu button to specify further measurement parameters. (The options from this menu will vary depending on the base units you have selected.)

After you select a new display mode, the statistics and graphs will refresh to reﬂect the current choice, as described below.

NOTE

Bar graphs are only available when Load is the selected base unit.

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 Errors	Packets received by the device interface that contained
	errors that prevented them from being 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 to a higher layer protocol (e.g., to free up
	buffer space in the device).
