In Versa, the machine state of 802.1x is depicted below: Picture 1Ĩ02.1x uses the Extensible Authentication Protocol to exchange messages during the authentication process. This document focuses on VOS as local authentication server. VOS supports a RADIUS server and a local authentication as the authentication server. Authentication server-A server that validates the credentials sent by the supplicant and determines what level of network access the end user or device should receive.The authenticator enforces both the locally configured network access policy and the dynamically assigned network access policy returned by the authentication server. Authenticator-A network access device that facilitates the authentication process by relaying the credentials of the supplicant to the authentication server. In this document, we are going to implement local authentication. With local authentication (that is, you do not use a RADIUS server or an identity provider server), the VOS interface acts as both the authenticator and the authenticating server. When a RADIUS server is the authenticating server, the VOS interface acts only as an authenticator and sends information about the supplicant to the authenticating server. A Versa Operating SystemTM (VOSTM) interface always acts as an authenticator.
