RADIUSis defined in RFC 2865. The IP Phone 1120E with SIP Firmware supportsonly the MD5 authentication method.802.1x defines the following three roles:1. Supplicant—an IP Phone that requires access to the network to usenetwork services.2. Authenticator—the network entry point to which the supplicant physicallyconnects (typically a Layer 2/3 switch). The authenticator acts asthe proxy between the supplicant and the authentication server. Theauthenticator controls access to the network based on the authenticationstatus of the supplicant.3. Authentication server—performs authentication of the supplicant.Enable and disable Network-level authentication through the EAPconfiguration menu.SIP Firmware Release 1.1 for IP Phone 1120E AdministrationNN43112-300 02.03 Standard27 May 2008Copyright © 2008, Nortel Networks.
