2-22 Bridge Statistics

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.

The discarding of good packets indicates a very busy network. If a device

routinely discards packets, it usually means that network trafÞc is overwhelming

the device. A change in network conÞguration (such as the addition of a bridge or

switch) may help reduce network congestion.

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).

Unknown Protocol

Displays the number of packets received which were discarded because of an

unknown or unsupported protocol. The device bridge interface will discard the

packet and increment this counter if it canÕt recognize the packet.

Packets Received

Displays the number of packets received by this interface.

Transmit Queue Size

The number of packets currently queued by the device 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 device begins to discard packets.

Packets Transmitted

Displays the number of packets transmitted by this interface.
