Ядрото съобщава, че състоянието на мрежовия интерфейс преминава в т.нар. promiscuous (безразборен) режим. В този режим, всички пакети, които минават в сегмента се приемат от драйвера на мрежовия интерфейс, а не само тези, предназначени за конкретната машина (или по-точно MAC адрес).

Основно се използва от снифъри, като tcpdump, ettercap, ethereal и др.
