To avoid having packets dropped. ICMPs may be dropped, they have the lowest priority. If you are flood pinging your network - which I suggest 100 pings per second is - some will be dropped.
The test takes a minute to run. I tried 25 mS, no difference. Any command that does ping tests fails the test.
The '-i' argument seems to set the time between pings to different machines, try using '-p' instead.
The same test, if run directly, without a switch, works perfectly.
On a ptp link, I'm sure it does.
The old router worked fine. They replaced the router, and I lost ALL connectivity switch-router. They replaced the router, and I have this, 30% loss. When I try any web site, there is a delay, compared to the old router. Many packages fail, but being TCP it tries again.
FWIW, between two office machines on the same Netgear Gbit switch, I think it is only shared with a printer - I ran fping --quiet -6 -p1 -c1000 - 0% loss. Okay, with your invocation, it does a ping per second, which you would think ought to be fine - still, from my TW test machine to our main firewall, at 1ping/sec, I also see 10% loss. (I think it traverses maybe three switches, I'm not sure). ICMPs can be ignored, just like UDP. -- Per Jessen, Zürich (10.8°C) Member, openSUSE Heroes (2016 - present) We're hiring - https://en.opensuse.org/openSUSE:Heroes
