How to match MAC to IP in BYOD environments with IPv4 and IPv6

L2 Linker


it is not easy to locate devices making trouble without having a reliable MAC-IP mapping in BYOD environments. With IPv4 we can solve this at the switches side with DHCP-Snooping ans ARP-Protect to assure that only IP addresses assigned by DHCP can be used.

With IPv6 I have to find a new solution assure only IP addresses I can map to a device enter the network. IPv6 privacy extension makes this worse.

One solution would be logging mac addresses in the firewall log like other vendors do.

One option would be, having a log of NDP changes.

Has anybody other options in mind.
