Parameters
-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 ICMP echo request sending interface by its type and
number. With the interface specified, the TTL of packets are set to 1 automatically to test the
directly-connected device (the IP address of the device is in the same network segment with 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.
