Using the STS16-20 Chassis View

The following three informational Þelds appear in the upper portion of the window:

Description

The interface description for the currently selected interface.

Address

The MAC (physical) address of the selected interface.

Type

The interface type of the selected port.

The lower portion of the window provides the following transmit and receive statistics. The Þrst four statistics are also displayed in pie charts.

Unicast

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

Non-Unicast

The number of packets transmitted to or received from this interface that had a destination address that is recognized by more than one device on the network segment. The multicast 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

The number of packets which were discarded even though they contained no errors that would prevent transmission. These statistics are displayed in the pie chart, color-coded magenta.

Good packets are typically discarded to free up buffer space when the network becomes very busy. If this occurs routinely, it usually indicates that network trafÞc is overwhelming the device. To solve this problem, you may need to reconÞgure your bridging parameters, or perhaps reconÞgure your network to add additional bridges or switches. Refer to the Network Troubleshooting Guide for details.

Error

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

Unknown Protocol (Received Packets only)

The number of packets received which were discarded because they were created under an unknown or unsupported protocol.

Packets Received (Received Packets only)

The number of packets received by the selected interface.
