Why Monitor the Switch
Any problem in your switch can affect a large proportion of your users.
Implementing a preventive approach to switch monitoring helps you to detect
problems early and to avoid potential problems.
With switch monitoring, you can gain visibility into the status and availability of
switch ports. You can actively monitor switch ports and quickly notify users if a
switch port or the switch fails.
When you access the device manager Dashboard and monitoring windows, you
can:
• Check the overall switch status and the switch vital signs.
• Verify connectivity for new users or devices.
• Check daily traffic patterns.
• Check for suspected problems by using the monitoring windows as a starting
point for further troubleshooting.
• Check for specific ports that could be causing problems.
• Get an overview of switch bandwidth usage and port statistics.
• View a history of switch activity.
Check the Front Panel LEDs
You can get a quick view of the overall condition of the switch by checking the
device manager Front Panel view (Figure 4-1).
