Statistics

The lower portion of the window provides the following transmit and receive statistics; note that the first four statistics are also graphically displayed in the pie charts.

Unicast

Displays 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

Displays 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 non-unicast field includes a count of broadcast packets — those 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 they contained no errors that would prevent transmission. Good packets are typically discarded to free up buffer space when the network becomes very busy; if this is occurring routinely, it usually means that network traffic is overwhelming the device. To solve this problem, you may need to re-configure your bridging parameters, or perhaps re-configure your network to add additional bridges. Consult the Cabletron Systems’ Network Troubleshooting Guide for more information.

These statistics are displayed in the pie chart, color-coded magenta.

Error

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

Unknown Protocol (Received only)

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

Packets Received (Received only)

Displays the number of packets received by the selected interface.

Transmit Queue Size (Transmit only)

Displays the number of packets currently queued for transmission from this interface. The amount of device memory devoted to buffer space, and the traffic level on the target network, determine how large the output packet queue can grow before the 9H42x-xx module will begin to discard packets.

Packets Transmitted (Transmit only)

Displays the number of packets transmitted by this interface.
