I need a solution with ARP and sniffer attacks

I need a solution with ARP and sniffer attacks from the local users !!! :open_mouth:

What does this mean? You need to explain what, exactly, you are trying to protect from. You can’t stop someone from sniffing the network. ARP poisoning is difficult to fix, unless you limit communications between the users. SO, you’ll need to explain, also, your network architecture if you want assistance.

ā€œsolution with attacksā€? =)

p.s. use static ARP entries

Yes, of course. But, the usefulness of this depends on the network architecture and devices. Not all devices are capable of static ARP entries. Therefore, I mentioned the need to control communications between devices on the network. Without that control, management can become problematic and burdensome. We still need more information in order to provide a useful answer.

then dhcp with mac-binding + mask /32 =)
