Tracking WLAN product support for pure 802.1X authentication methods
Although 802.1X allows many authentication methods, the one most consistently supported is PEAP with MSCHAPv2. While pure 802.1X support is widespread in the other access points and wireless switching systems tested, the role of those products in the 802.1X handshake is to simply act as an intermediate point inside the tunnel between supplicant and authentication server. The authentication method used is irrelevant to the access point (although some access points do restrict the types of authentication allowed).
