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.
