My netdata reports dropped packets each exactly 10 seconds. I’ve found theres a MS NLB packet in my network (from 02:01:00:00:00:00 to FF:FF:FF:FF:FF:FF) each 10 seconds. The curious thing is that dropped packets stops appearing while I do a thark or tcpdump (no matter if I’m using promiscuos mode or not) I know this is not a netdata problem. ---

Hi @Alfrenovsky > The curious thing is that dropped packets stops appearing while I do a thark or tcpdump This is expected, the capture is done in [promiscuous mode](https://en.wikipedia.org/wiki/Promiscuous_mode). That is why nothing is dropped. ---

Even if I capture with --no-promiscuous-mode I can see the packets and there’s no dropped The dropped packets seems to be because they are from an unknown or unsupported protocol.
