CH A P T E R 4 Troubleshooting • Diagnosing Problems, page 4-1 • Clearing the Switch IP Address and Configuration, page 4-4 • Finding the Switch Serial Number, page 4-5 Diagnosing Problems The LEDs on the front panel provide troubleshooting information about the switch. They show power-on self-test (POST) failures, port-connectivity problems, and overall switch performance. You can also get statistics from the CLI or from an SNMP workstation.
Appendix 4 Troubleshooting Diagnosing Problems Switch LEDs You must have physical access to the switch to do this. Look at the port LEDs for troubleshooting information about the switch. See the “LEDs” section on page 1-7 for a description of the LED colors and their meanings. Switch Connections Bad or Damaged Cable Always examine the cable for marginal damage or failure.
Appendix 4 Troubleshooting Diagnosing Problems • Verify that you are using the correct cable type. See Appendix B, “Connector and Cable Specifications,” for more information. • Look for loose connections. Sometimes a cable appears to be seated, but is not. Disconnect the cable and then reconnect it. SFP Module Port Issues Use only Cisco SFP modules on the switch. Each Cisco module has an internal serial EEPROM that is encoded with security information.
Appendix 4 Troubleshooting Clearing the Switch IP Address and Configuration Switch Performance Speed, Duplex, and Autonegotiation If the port statistics show a large amount of alignment errors, frame check sequence (FCS), or late-collisions errors, this might mean a speed or duplex mismatch. A common issue with speed and duplex is when the duplex settings are mismatched between two switches, between a switch and a router, or between the switch and a workstation or server.
Appendix 4 Troubleshooting Finding the Switch Serial Number To reset the switch: 1. At the switch prompt, enter enable, and press Return or Enter. 2. At the privileged EXEC prompt, switch#, enter setup, and press Return or Enter. The switch displays the prompt to run the initial configuration dialog. The switch now behaves like an unconfigured switch. You can configure the switch by using the CLI setup procedure described in Appendix C, “Configuring the Switch with the CLI-Based Setup Program.
