NAC in a Single WLC, multiple site scenario

[faimymolina]

Hello:

I have the following network and would like to know whether I need a WLC per site.

There are 3 different sites with the followig equipment:

Main site: one NAC server (CAS), one NAC manager, several APs

Branch 1: one NAC server (CAS), several APs.

Branch 2: one NAC server (CAS), one WLC, several APs.

I´ve read that in order to function properly, WLC and CAS server must be L2 adjacent. Does that mean that I need one WLC per site, or it means that WLC + CAS in Branch2 would control wireless APs users in all three locations, as long as they (WLC + CAS in Branch2) are both L2 adjacents?

Any advice would be very appreciated.

Best regards and thanks in advance.

Faimy.
