Witam
Pojawiły mi się na sieciówce dropy na rx'ie, od kiedy dokładnie nie 
wiem. w kazdymbądź razie klient "traci pakiety", co prawda nie ma sla 
ale dzięki niemu widzę, coś dziwnego na ethernecie.

patrząc na ten licznik dropów nie za każdym razem odświerzenia się 
zmienia, ale w momencie jego zmiany wyalane są do niego pakiety.

czym to może być spowodowane? podejrzewam, że coś elektrycznie. 
wymieniłem kabelek, ale nie wiele to pomogoło (co prawda tej samej firmy 
co ten pierwszy ale jednak inny). jest to wpięte do cisco cat65 i spina 
się to po gigabicie
