transmitted, ranging from 1 to 4,294,967,295. The default value is five.
-d: Configures the socket to be in DEBUGGING mode.
-f: Configures the packet to be dropped instead of being fragmented when the packet
length is larger than interface MTU.
-h ttl: Configures TTL value for echo requests to be sent, range from 1 to 255. The
default value is 255.
-i: Configures to choose packet sent on the interface.
interface-type: Specifies the interface type.
interface-number: Specifies the interface number.
-n: Configures to take the host parameter as IP address without domain name
resolution.
-p: pattern is the hexadecimal padding of ICMP echo-request, for example -p ff pads
the packet completely with ff. By default, the starting padding is 0x01, crescent, and the
ending padding is 0x09, and then repeat.

-s packetsize: Specifies the length of ECHO-REQUEST (excluding IP and ICMP packet
header) in bytes. The length of the echo-request packet defaults to 56 bytes.
-t timeout: Maximum waiting time after sending the echo-request (measured in ms).
The time defaults to 2000 ms.
-tos tos: Specifies TOS value for echo requests to be sent, range from 0 to 255. The
default value is 0.
-v: Displays other received ICMP packets (non echo-response). By default, no other

Description
Use the ping command to check the IP network connection and the reachability of the
host.
The ping command sends ICMP ECHO-REQUEST message to the destination. If the
network to the destination works well, then the destination host will send ICMP
ECHO-REPLY to the source host after receiving ICMP ECHO-REQUEST.
