Usage Guidelines
-
The ping command is used to check whether the destination IP address is reachable.
-
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.
