The ping command is used to verify the internal IP configuration on a local host. The Wikipedia Page has good information on it. The figure shows the first step in the testing sequence. ![]() I don't know if I explained it very well, but it was the best I could do. You did not explain what is the IP address of the loopback on your Catalyst 2960 but I assume that it is in a different subnet than 10.0.33.0/24 (just as it should be). This would provide the information to local applications, while disabling the ability for somebody else on a LAN to access whatever server software you set up as local. Both prompts can be used to get the Loopback address of our machine. You can specify the server software to transfer information via the loopback address and your client software could listen in on the loop back address. Step 1: Open the Command Prompt in Windows OS by pressing the Windows Key+R and typing cmd into the input box. This can be seen when you have a server-client model application installed on the local computer, but you do not want that information to be accessible remotely. ![]() It can also be used to specify to your applications that you do not want your information to leave the host computer. If you suspect that your NIC is not working on a physical level, this makes a very good test. When you do this you are testing to make sure that your information can go down to layer 1 and back up. When you test your NIC, this can be done via "ping 127.0.0.1". ![]()
