Freeradius with DHCP and VLANs

[Fernando Pizarro]

Hi all,

I'm using Freeradius version 2.1.12 with MySQL backend and EAP-TLS 
authentication to serve dynamic VLAN and a DHCP server to leases this IP 
address. This setup work sucefully but IP address of supplicants doesn't 
stored in the database.

Is there any setup to store IP address of supplicants in the database?
How sqlippoll works? does it work as a DHCP server?
Is it posible to setup Freeradius with DHCP module to server diferents 
VLANs?

Thanks for all.
Fernando
