Troubleshooting
The LEDs on the front panel of the Catalyst 2900 series XL switch 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 1-9.
You can also get statistics from the browser interface, from the command-line interface (CLI), or from an SNMP workstation. See the Catalyst 2900 Series XL and Catalyst 3500 Series XL Software Configuration Guide, the Catalyst 2900 Series XL and Catalyst 3500 Series XL Command Reference, or the documentation that came with your SNMP application for details.
