Chapter 4 Troubleshooting Diagnosing Problems port. Use the show interfaces privileged EXEC command to check the port or interface error-disabled, disabled, or shutdown status on both sides of the connection. If needed, re-enable the port or the interface. Ping End Device Check the end device by pinging from the directly connected switch first, 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 How to Clear the Switch IP Address and Configuration • If a remote device does not autonegotiate, configure the duplex settings on the two ports to match. The speed parameter can adjust itself even if the connected port does not autonegotiate. Autonegotiation and NIC Cards Problems sometimes occur between the switch and third-party network interface cards (NICs). By default, the switch ports and interfaces are set to autonegotiate.
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. See Figure 4-1 to find the serial number on your switch. You can also use the show version privileged EXEC command to get the switch serial number.
