Dynamic VLAN and FreeRadius

I possess a device from D-Link (DWS-3024). it is a wireless switch controler, and the documentation says that:
 - One SSID has to be affect to one VLAN on the profile.
 - An Access point could be configured with up to 8 ifferent SSIDs and it is possible to affect each SSID on its own network (below is a link which show you the config page) or all SSID on the same network.  maybe i didn't read it correctly, so here is the link (see page 89-90 and maybe 91 too.): ftp://ftp.dlink.fr/DWS/DWS-3024/Manuel/DWS-3000_Series_User_Manual_v2.00.pdf

i asked you stuffs about SSIDs/VLAN cause all my APs (about 30) will receive the same profile, and the profile will have 3 differents SSIDS with diffrents security access levels and network from the wireless switch. 

for example, in the same room, associated to the same AP, students and teachers will connect to diffrent SSIDs coming from that same AP, and some will have to athenticate via EAP-PEAP, other will require EAP-TLS.

this other short file explain point to point what is my config and waht i am trying to do:
read it and maybe you could understand me.

  That doesn't make sense.  SSID's aren't tied to VLANs, unless you
configure them that way.

  No... SSID's have nothing to do with VLAN's.

  Read your NAS documentation to see how to do VLAN assignment, and how
it interacts with SSID's.

  Stop talking about "SSID/VLAN".  They are separate things.

  When you do VLAN assignment with RADIUS, you do NOT need to

  What does that mean?
