the leds on the front panel provide troubleshooting information about the switch. they show failures in the power-on self-test (post), port-connectivity problems, and overall switch performance. for a full description of the switch leds, see the “leds”?section on page 2-8.

    you can also get statistics from the browser interface, from the command-line interface (cli), or from a simple network management protocol (snmp) workstation. refer to the software configuration guide, the switch command reference guide on cisco.com, or the documentation that came with your snmp application for details.
