Broken—No cable attached.

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 through segmentation.

Frames Forwarded—A running average of the pro- portion of the received frames 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.
