CH A P T E R 4 Troubleshooting This chapter contains the following topics: • Diagnosing Problems, page 4-1 • Resetting the Switch to the Factory Default Settings, page 4-5 • Finding the Switch Serial Number, page 4-5 Diagnosing Problems The switch LEDs provide troubleshooting information about the switch. They show POST failures, port-connectivity problems, and overall switch performance. You can also get statistics from the device manager, the CLI, or an SNMP workstation.
Chapter 4 Troubleshooting Diagnosing Problems Switch Connections Bad or Damaged Cable Always examine the cable for marginal damage or failure. A cable might be just good enough to connect at the physical layer, but it could corrupt packets as a result of subtle damage to the wiring or connectors. You can identify this problem because the port has many packet errors or it constantly flaps (loses and regains link). • Exchange the copper or fiber-optic cable with a known good cable.
Chapter 4 Troubleshooting Diagnosing Problems • Verify the status of all ports. See Table 1-8 on page 1-10 for descriptions of the LEDs and their meanings. • Use the show interfaces privileged EXEC command to see if the port is error-disabled, disabled, or shut down. Re-enable the port if necessary. • Verify the cable type.
Chapter 4 Troubleshooting Diagnosing Problems Spanning Tree Loops STP loops can cause serious performance issues that look like port or interface problems. A unidirectional link can cause loops. It occurs when the traffic sent by the switch is received by the neighbor, but the traffic from the neighbor is not received by the switch. A broken cable, other cabling problems, or a port issue could cause this one-way communication.
Chapter 4 Troubleshooting Resetting the Switch to the Factory Default Settings Resetting the Switch to the Factory Default Settings Follow these steps to return your switch to the factory default settings. Note Resetting the switch deletes the configuration and reboots the switch. 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.
