Hi, here a couple answers

1.- You can do this in Authentication - AAA Profiles - You AAA profile - Enforce DHCP

2.- The "enforce-dhcp" option under the AAA Profile on the controller ensures only the clients that gets an IP address from a DHCP server be allowed in the controller's user-table. Any client that configures a static IP address would not be allowed in the user-table and so it cannot pass any traffic.


This link from the community explains it. I just put the image in version 8.

3.- What do you mean by optimized de MDNS and airdrop multicast process? Could you elaborate I lit bit more?

I hope this helps
