Statistics Window Fields

The following informational and statistics Þelds appear in the interface Statistics window.

Three informational Þelds appear in the upper portion of the window:

Description

Describes the interface description for the currently selected port.

Address

Displays the MAC (physical) address of the selected port.

Type

Displays the interface type of the selected port.

The following transmit and receive statistics Þelds are displayed in the lower portion of the window. The Þrst four statistics are also graphically displayed in a pie chart. The statistics are read directly from the device, and are updated with each poll from SPECTRUM Element Manager to the device.

Unicast

Displays the number of packets transmitted to, or received from, this interface that had a single, unique source or destination address. These statistics are displayed in the pie chart (color-coded green).

Non-Unicast

Displays the number of packets transmitted to, or received from, this interface that had a source or destination address that is recognized by more than one device on the network segment. The non-unicast Þeld includes a count of broadcast packetsÑthose that are recognized by all devices on a segment. These statistics are displayed in the pie chart (color-coded dark blue).

Discarded

Displays the number of packets which were discarded even though no errors were detected to prevent transmission. One possible reason for discarding such a packet could be to free up buffer space.

Discarding good packets indicates a very busy network. If a device routinely discards packets, it usually means that network trafÞc is overwhelming the device, perhaps because the device is performing poorly.

These statistics are displayed in the pie chart (color-coded hot pink).

Error

Displays the number of packets received or transmitted that contained errors. These statistics are displayed in the pie chart (color-coded red).
