Help with example to setup WISPr-Bandwidth-Max-Up + WISPr-Bandwidth-Max-Down reply

Hi Guyz, Using freeradius with mysql for authentication 'n accounting and it works well. Clients get authenticated and kicked when time is up. Now need to send bandwidth control parameters (WISPr-Bandwidth-Max-Up + WISPr-Bandwidth-Max-Down) to my NAS My NAS supports traffic shapping and these atribs specifically (WISPr-Bandwidth-Max-Up and WISPr-Bandwidth-Max-Down). Just need some help with example of records to add in radreply, radcheck and an entry counter.conf Any lead to a documentation that can help will be highly appreciated. Grace
