Radius + 802.1X

[Emerson]

Hi,

i posted 2 messages with Radius + Dhcp and Radius with ip pool, but for 
this answers, i learn that radius don't have anithing with dhcp, and ip 
pool work with connections PPP.
But I need to deliver ip's to my clients, they use wifi hardware 802.1X.
Why i deliver ip's for them ?
My freeradius work ok, and i put dhcp to work together, but not work, 
anyone can answer this for me ?
Anyone have any experience with it ?

Thank's.....
