I would be more then happy to experiment and try it if someone pointed me in the right direction :)
This deployment is at a school, we are lucky to have what we have clearpass probably isn't going to happen.
The problem i'm running into is all of these devices coming into one part of the building, then moving to another. So with three different vlans there is a chance a single device will have a lease for 3 IP's.
Just trying to find a way to force some devices off onto a different dhcp scope to free up room for other devices.
