Current Utilization—The percentage of bandwidth usage for the port you are currently viewing. This value indicates the general traffic level on the individ- ual port. Ideally, this figure should be below 60%, which indicates that the port is responsible for a rea- sonable amount of traffic relative to the entire ring.

High utilization values suggest that you should adjust the network topology by reducing load on that port by segmentation.

Frames Forwarded—A running average of the pro- portion of the received frames that are forwarded. This value is expressed as a percentage of all received frames, based on a sampling interval of 20 seconds.

Broadcast Frame Bandwidth—A running average of the broadcast frame bandwidth. This value is expressed as a percentage of theoretical maximum bandwidth availability, based on a sampling interval of 20 seconds.

Error Frames—This field displays a running average of the percentage of error frames with CRC errors and is based on a sampling interval of 20 seconds.

Port Statistics (Traffic)

The TR Port Statistics (Traffic) screen provides a more detailed display of statistics for the port you are view-

ing. A typical TR Port Statistics (Traffic) screen appears in Figure 6-4.

The TR Port Statistics (Traffic) screen displays this information:

Unit ID—The identifying number of the unit you are viewing.

Port ID—The identifying number of the port you are viewing.

Frames Received—The total number of frames that have been received by the port including frames with errors.

Frames Transmitted—The total number of frames transmitted by the port, including frames with errors.

Multicasts Received—The number of frames suc- cessfully received with a multicast destination address. This number does not include frames
