am sters ce nu era interesant. Ce e interesant e dece ai de 3.26x mai multe
pachete filtered decit received. Incearca sa pui in portul ala ceva
computer/laptop care nu filtreaza pachetele ca sa vezi cu un tcpdump ce
trafic e acolo. Filtrul ala din un google rapid e in NIC deci pachetele
filtrate nu ajung la linux. Poate ai gramada de pachete non IP/ARP care
switch-ul le arunca pe toate interfetele din ceva motiv dar e interesant de
vazut ce trafic e ala.
