IP Troubleshooting Procedures
The General approach of the process of troubleshooting TCP/IP connectivity issues with the assumption that you will have access to the client and may not have access to the server. If the problem is determined to be a server issue, you contact the server administrator. If you are the server administrator you can apply the troubleshooting process in reverse server to client to further troubleshoot connectivity issues. To efficiently troubleshoot a TCP/IP connectivity problem it is necessary to identify a single pair of source and destination devices that are exhibiting the connectivity problem. When you've selected the two devices test to make sure that the problem is actually occurring between these two devices. Possible problems include these. Physical layer issue somewhere along the path. First hop Layer 3 connectivity issue local LAN segment. Layer 3 IP connectivity issue somewhere along the packet's path. According to the cisco site, below are some starting points they suggest. Try to ping from the source to destination device by IP address. If the ping fails verify that you are using the correct address and try the ping again. If the ping still fails go to the next section Troubleshooting Local Connectivity Problems proceed to Step. Try to ping from the source to the destination device by name. If the ping fails verify that the name is correctly spelled and that it refers to the destination device and then try the ping again. If the ping still fails go to the section Troubleshooting Domain Name Server Problems. If you can ping the destination by both name and address it appears that the problem is an upper layer problem.
