DAI is a self-defeating misfeature which can result in a self-DoS of the 
switch.  Don't enable it!

DHCP Snooping and IP Source Guard are very useful anti-spoofing 
mechanisms, and should be enabled on the access ports.

Also, Root Guard, Loop Guard, and BPDU-Guard should be enabled in a 
situationally-appropriate manner.
