Diagnosing Problems

The switch LEDs provide troubleshooting information about the switch. They show boot fast failures,
port-connectivity problems, and overall switch performance. You can also get statistics from Web UI, the
CLI, or an SNMP workstation. See the appropriate configuration guide, or the documentation that came with
your SNMP application for details.

Switch Boot Fast

Contact your Cisco TAC representative if your switch does not successfully boot.
