Interpreting the Statistics
■
The Utilization graph scales automatically to display the percentage
of bandwidth used on all ports of the Switch over the last 30
seconds:
■
A bandwidth utilization of 0–25% (green bar on the graph)
indicates that the ports are dealing with a light traffic load.
■
A bandwidth utilization of 26–85% (yellow bar on the graph)
indicates that the ports are dealing with a normal traffic load.
■
A bandwidth utilization of 86–100% (red bar on the graph)
indicates that the ports are 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 ports of
the Switch over the last 30 seconds.
