No this configuration is still incorrect. From network engineer perspective that configuration assumes that could be one ip address with different mac addresses at the same time. This is a network issue. Don't do that.
I know that, I'm the network engineer. But there are lots of other reasons for duplicate IP addresses, so I would not bother for this additional one, given the fact that it is much easier to generate duplicate IP addresses when setting them up manually instead of using DHCP for it. We also have a bunch of switch stacks that need DHCP. They often come up with different stack master and therefore different MAC address, so this feature would help us a lot. Sure, it's just like a "bug fix" for vendors not being able to handle out consistent MAC addresses from their switch stacks but unfortunately we have to work with it.
If you want to share the same ip address with different devices consider using option 82 and assign addresses based on port.
We can't do that.
you also can make user class with test where you provide your mac addresses as key and assign that class to reserved ip address. I've never do that way, but could work.
I will test that in the next days.
