Run the ping command by setting a destination IP address to check whether the network connection to the destination IP address is normal.
If the destination IP address is unreachable, the system displays a message indicating that the request times out.
If no route is available to the destination IP address, an error message is displayed.
This command can be used only after the TCP/IP protocol stack is enabled.
