We will also make sure that no clients can talk to each other on these networks. We will try to drive all users to the secure network. The secure network will also be NAC enabled.
The open network will tunnel back to the controller and bridge there which is required due to the captive portal.
The only possible snag here is roaming between buildings and between 802.1x APs. I have not tested and tweaked that yet.

> We will soon be migrating our wireless network from Cisco autonomous 1231 APs to a combination of Cisco 3502i along with some of the existing 1231 APs converted to lightweight. As we prepare for this we are looking at how to best architect the new network. The new network will cover the entire campus which consists of approx 50 buildings, with each building having its’ own VLAN.
> The initial idea was to install the APs so the IP address of the AP would be a part of the local building VLAN. This is the IP the AP would use to talk back to the controller. For user connections there would be two VLANs created which would be accessed through a single SSID. The users would then be dynamically assigned to one of the two VLANs based on their logon credentials. Currently all users are placed on the same VLAN after authentication, as our current installation is not capable of dynamic VLAN assignment. There is currently only a single SSID in place.
