CH A P T E R 4 Troubleshooting 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 1-4. You can also get statistics from the browser interface, from the command-line interface (CLI), or from a Simple Network Management Protocol (SNMP) workstation.
Chapter 4 Troubleshooting Diagnosing Problems Verify Switch POST Results As the switch powers on, it begins the POST, a series of tests that runs automatically to ensure that the switch functions properly. It might take several minutes for the switch to complete POST. When the switch begins POST, the system LED slowly blinks green. When POST completes, the system LED blinks amber. If POST fails, the system LED remains amber. If POST completes successfully, the system LED rapidly blinks green.
Chapter 4 Troubleshooting Diagnosing Problems Ethernet and Fiber Cables Make sure that you have the correct cable type for the connection: • For Ethernet, use Category 3 copper cable for 10 Mb/s unshielded twisted pair (UTP) connections. Use either Category 5, Category 5e, or Category 6 UTP for 10/100 or 10/100/1000 Mb/s connections. • For fiber-optic connectors, verify that you have the correct cable for the distance and port type.
Chapter 4 Troubleshooting Diagnosing Problems Use the show interfaces privileged EXEC command to verify the port or interface error-disabled, disabled, or shutdown status on both sides of the connection. If necessary, re-enable the port or the interface. Ping the End Device Verify the end device connection by first pinging it from the directly connected switch, and then work your way back port by port, interface by interface, trunk by trunk, until you find the source of the connectivity issue.
Chapter 4 Troubleshooting Clearing the Switch IP Address and Configuration To maximize switch performance and to ensure a link, follow one of these guidelines when you set or change the settings for duplex and speed: • Let both ports autonegotiate both speed and duplex. • Manually set the speed and duplex parameters for the ports on both ends of the connection. • If a remote device does not autonegotiate, configure the duplex settings on the two ports to match.
Chapter 4 Troubleshooting Finding the Switch Serial Number Finding the Switch Serial Number If you contact Cisco Technical Assistance, you need to know the serial number of your switch.
