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.

Example

Run ping 192.168.1.3.

Output

Ping a TFTP server IP address.

OHOS:/$ ping 192.168.1.3
