Security Against ARP Spoofing

[PRASAD BAIT]

Hi,

I am planning to create two DHCP servers for DHCP load balancing. Since ARP Spoofing is one of major threats while configuring DHCP, I want to know what are the ways to prevent ARP spoofing.

Yes, you can do that. Your solution will be dhcp snooping on the switch that your hosts connect to and then you will be good to go.

Here is the doc for it http://www.cisco.com/en/US/docs/switches/lan/catalyst4500/12.1/13ew/configuration/guide/dhcp.html

And one useful pdf is here.

I hope it helps.
