I have a network supported by Mikrotik-routers.Since two week I have very strange problem.While everything is working suddenly the switches stopped working after a remote reset I began to have all my neighbor mac address in the neighbor list but with ping missing and vice versa ping them but don't see them in the neighbor list.Did this happened to someone?Could it be possible someone to flood my network?And can you give me an advice how to catch him....

I have seen (suspected) power spikes cause router boards various problems, ip address list not show up through winbox etc.
