-c option: count
<count> parameter: value: numeric: “[n ... ]n”
number of packets to send
-s option: size
<size> parameter: value: numeric: “[n ... ]n”: bytes
size of packet to send
-w option: wait
<wait> parameter: value: numeric: “[n ... ]n”: seconds

DESCRIPTION: To verify the operational status of the Ethernet interface the command
“ping” is used. This command tests the network connection and target
server’s ability to respond.
If no other parameters are specified, four requests will be sent. This
can be changed with the parameter “-c”. The typical size of a ping
packet can be changed with the parameter “-s” and the time between
requests, which is typically one second, can be changed with the pa-
rameter “-w”.
Reponses to the “ping” command are dependent on the performance
of the network.
USAGE: Send four packets
COMMAND / RESPONSE:
ping 192.192.158.7

packets
COMMAND / RESPONSE:
