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.
