DAI (Dynamic ARP Inspection)

Hi Laz,

1)I am confused about when should I use arp access-list option and when DAI
with trusted int option?, can we use both simultaneously?

  1. As per my understanding of this topic, if we configure DAI in that case DCHP
    snooping must have already configured.

  2. Do we have to use trust command on interface for both cases or for any one of the case will be sufficient?

  3. Do we need to configure these sec technology on all the switches on our n/w?
