Statistics

Type

Displays the interface type of the selected port: ethernet-csmacd, fddi, or atm. Note that there is no type distinction between Ethernet and Fast Ethernet.

The lower portion of the window provides the following transmit and receive statistics; note that the Þrst 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 Þeld includes a count of broadcast packets Ñ 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 trafÞc is overwhelming the device. To solve this problem, you may need to re-conÞgure your bridging parameters, or perhaps re-conÞgure 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 trafÞc level on the target network, determine how large the output packet queue can grow before the SmartSwitch 7000 will begin to discard packets.
