2.1 Network Connectivity Test Commands

2.1.1 ping
Syntax
ping [ -a ip-address | -c count | -d | -f | -h ttl | -i interface-type interface-number | -n | - p
pattern | -q | -r | -s packetsize | -t timeout | -tos tos | -v | ip ]* host-ip
ping ipx ipx-address [ -c count | -s packetsize | -t timeout ]*
ping clns nsap-address

Parameter
-a ip-address: Sets the source IP address to send the ICMP ECHO-REQUEST packets.
-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: Sets the socket to DEBUGGING mode. By default, it is non-DEBUGGING mode.
-f: Specifies to discard a packet directly instead of fragmenting it if its length is greater
than the MTU (maximum transmission unit) of the interface.
-h ttl: Sets the TTL (time to live) value of the echo request packets in the range of 1 to
255. By default, the TTL value is 255.
-i: Selects the specified interface to send the ICMP packets.
interface-type: Interface type.
interface-number: Inferface number.
-n: Specifies to 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 only
ff. 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 and not to display the details. By default, all
the information including the details and statistics will be displayed.
