Interpreting the Statistics
■
The Utilization graph scales automatically to display the percentage of 
bandwidth used on the port over the last hour and last 48 hours:
■
A bandwidth utilization of 0–25% indicates that the port is dealing 
with a light traffic load.
■
A bandwidth utilization of 26–85% indicates that the port is 
dealing with a normal traffic load.
■
A bandwidth utilization of 86–100% indicates that the port is 
dealing with a heavy traffic load. This could be caused by a fault in 
your network, or an inadequate network configuration.
■
The Total Errors graph scales automatically to display the total number 
of packets with errors that have been seen on the port over the last 
hour and last 48 hours.
■
The Packet Size Distribution graph displays the proportion of packets 
of certain sizes seen by the port over the last 30 seconds.
