Help request on the EAP-TTLS V1 in freeradius

Hello, Currently we try to use the freeradius to simulate AAA server in our lab, we had succeeded in using the EAP-TTLS V0 before. Now we want to introduce the EAP-TTLS V1 in the next step, but I didn't find any new information from the web. Is there any expert can answer me??
