Port Utilization
You can choose which types of network traffic to display and in what format:
• Types of traffic—By default, all traffic is displayed for all interfaces. Click
the links above the display area to display all traffic, errors, received traffic,
or transmitted traffic.
• Formats—Click the buttons below the display area to view the data in
Chart Mode or Grid Mode.
• Chart details—When displaying a chart, position your mouse pointer over
a bar or a point on the chart to view the data.
As you monitor the usage on the ports, note whether the percentage is what you
expect during that given time of network activity. If usage is high when you
expect it to be low, a problem can exist. Bandwidth allocation can also be based
on whether the connection is operating in half-duplex or full-duplex mode.
These are some of the reasons for errors received on or sent from the switch ports:
• Bad cable connection
• Defective ports
• Software problems
• Driver problems
Data is collected at each 60-second system refresh.
Refer to
Monitor Trends on page 170 for a graph to view per-port patterns over
incremental instances in time (by 60 seconds, 1 hour, 1 day, or 1 week).
Refer to
Monitor Port Statistics on page 171 for details on the specific port errors
detected on each port.
