Ping

Hello to everybody,
I'd like to ask you to explain me what is the reason to use the -l option
with ping command. What should be the result of this command and how to
interpret result. What can say the result of command : ping -l 1000 -c 20
ip_addr if you observe 90 % of lost packets is it normal situation?
Thanks for all suggestions, regards.

You ask ping to send 1000 packets as fast as it can, you also limit the
number of packets to 20 before ping exits. In my book this will give 20
replies for 1000 transmitted, ie packet loss of 98%.

That option allows you to send out several pings in quick succession,
without waiting for a reply. This could be used for testing for congestion
etc. Normally, ping is sent one packet at a time with a wait in between
for a reply.

Why does this sound like a homework question?

OK I understand It was mistaken I understood the -c option different way.
Now everything is clear. Thanks a lot
