I currently am running about 4 VLANS:
STAFF
STUDENT
IT-Admin
Guest
Whenever I try to connect a Chromebook to Student, the Chromebook usually returns an error of DHCP lookup Failed if they don't already have an entry in the DHCP server. If I try to connect the Chromebook to our Guest network or Staff, then they connect just fine with no issues. Guest does not have any Policy Rules but both Staff and Student have Allow 53, Allow 67, and Allow 68.
