EAP Authentication
EAP (Extensible Authentication Protocol) is an Enterprise authentication protocol that can be used in
both a wired and wireless network environment. EAP requires the use of an 802.1x Authentication
Server, also known as a Radius server. Although there are currently over 40 different EAP methods
defined, the current internal Modero 802.11g wireless card and accompanying firmware only support the
following EAP methods (listed from simplest to most complex):
 EAP-LEAP (Cisco Light EAP)
 EAP-FAST (Cisco Flexible Authentication via Secure Tunneling, a.k.a. LEAPv2)
The following use certificates:
 EAP-PEAP (Protected EAP)
 EAP-TTLS (Tunneled Transport Layer Security)
 EAP-TLS (Transport Layer Security)
EAP requires the use of an 802.1x authentication server (also known as a Radius server). Sophisticated
Access Points (such as Cisco) can use a built-in Radius server. The most common RADIUS servers used
in wireless networks today are:
 Microsoft Sever 2003
 Juniper Odyssey (once called Funk Odyssey)
 Meetinghouse AEGIS Server
 DeviceScape RADIUS Server
 Cisco Secure ACS
