Port Utilization and Port Errors Graphs
You can see the following information on port performance:
• Port Utilization Graph: Displays the received utilization (blue) and sent
utilization (purple) on each port.
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 might exist.
Bandwidth allocation can also be based on whether the connection is
operating in half-duplex or full-duplex mode.
• Port Errors Graph: Displays the total percentage of errors on each port.
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 Trends Graphs on
page 98 for a graph that shows per-port patterns over incremental instances in
time (by 60 seconds, 60 minutes, 24 hours, or 14 days).
Refer to Port Statistics on page 101
for details on the specific port errors
detected on each port.
OK Green Switch internal temperature is within the acceptable temperature range.
Faulty Red Switch internal temperature is above the upper temperature threshold.
