Network blocked by ARP flooding

  Hi,

  I am facing network issue by ARP flooding. Due to this my network went down. Find the attached screenshot for reference.

Hello, Krunal.

You could try to capture ARP traffic and see (by MAC) who is abusing your network.

By capturing ARP traffic I found 1 DHCP server is sending malicious traffic into network. so how can I stop it?

What kind of malicious traffic are we talking about?

Thanks

If this is not one of your managed DHCP servers (i.e it should not be on the network) then you need to look at DHCP Snooping.
