Parameter
-a ip-address: Specifies the source IP address to send ICMP ECHO-REQUEST packet. This IP address
must be a local interface IP address.
-c count: Specifies how many times the ICMP ECHO-REQUEST packet will be sent. The count
argument is the times, which ranges from 1 to 4,294,967,295 and defaults to 5.
-d: Specifies the socket to be in DEBUGGING mode. By default, the socket is in non-DEBUGGING
mode.
-f: Specifies to discard a packet directly instead of fragmenting it if its length is greater than the
maximum transmission unit (MTU) of the interface.
-h ttl: Specifies the time to live (TTL) value of the ICMP ECHO-REQUEST packets in the range 1 to 255.
By default, the TTL value is 255.
-i interface-type interface-number: Specifies the interface that sends ICMP ECHO-REQUEST packets
by its interface type and number. After the interface is specified, the TTL of the ICMP ECHO-REQUEST
packet is set to 1 to test the directly-connected device (the IP address of the device is in the same
network segment as that of the interface).
ip: Specifies the device to support IPv4. By default, the device supports IPv4.
-n: Specifies to directly regard the host argument as an IP address without performing domain name
resolution. By default, the host argument is first regarded as an IP address; if it is not an IP address,
domain name resolution is performed.
-p pattern: Specifies the padding byte pattern of the ICMP ECHO-REQUEST packets. The pattern
argument is a byte in hexadecimal. For example, -p ff fills a packet with all ffs. By default, the system fills
a packet with 0x01, 0x02, and so on, until 0x09; then it repeats this procedure from 0x01 again.
-q: Specifies to display only the statistics without the details. By default, all the information including the
details and statistics will be displayed.
-s packetsize: Specifies the size (in bytes) of each ICMP ECHO-REQUEST packet (excluding the IP
and ICMP headers). The packetsize argument ranges from 20 to 32,000 and defaults to 56 bytes.
