Check out the Windows Server Customer Advisory Team (WinCAT) post Network Access Protection Using 802.1x VLAN’s or Port ACLs – Which is right for you?
Our very own Pat Fetty, whom many of you have seen presenting NAP talks at industry conferences, discusses the two ways that you can configure IEEE 802.1X-based switches and wireless access points for NAP using virtual LANs (VLANs) and access control lists (ACLs). Pat then compares the two approaches with their respective pros and cons.
This is very valuable information to review prior to beginning your 802.1X enforcement deployment.
