Table 1 Parameter description

Parameter	Description	Value Range
–help	Displays the parameters supported by the ping command.	N/A

-c CNT	Specifies the number of execution times. The default value is 3.	1-65535
-f	Pings an IPv4 address in implicit mode. The default parameter configuration is equivalent to -c 15 -i 0.2.	N/A

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.

Run ping 192.168.1.3.
