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?

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.
