You can use the ping command to verify that computers on the Ethernet network can communicate with other computers on the network.
To use the ping command, you must have a computer configured to use the TCP/IP protocol and at least one other computer connected to the network.
To verify the computers can communicate on the network using the ping command:
- Open a Command Prompt window (cmd) on the computer.
-
Type the ping command. Use the format ping <address>, where <address> is the IP address or domain name of the computer you want to ping. (For example: 198.81.196.2, www.jci.com, or NAE 008066050FFC.)
-
Press Enter.
If you receive a reply, the computers are communicating on the network.
If you do not receive a reply, try pinging your own computer address.
-
If you can ping your own address but not any other addresses, the problem is with the network. Check the Link light on the network card.
-
If you cannot get a reply from your own address, the problem is probably with the network card in your computer or with the TCP/IP properties. Check the network card in your computer, and verify the TCP/IP properties.
