The device can authenticate users who try to log in based on user accounts configured on the device itself. The device can also use an external authentication server to authenticate a large number of users. The device supports RADIUS (Remote Authentication Dial-In User Service, see Section 8.4.6.2 on page 225) and TACACS+ (Terminal Access Controller Access-Control System Plus, see Section 8.4.6.2 on page 225) as external authentication, authorization and accounting servers. Figure 175 Authentication Server Client Authentication Server 8.4.6.1 Local User Accounts By storing user profiles locally on the device, your device is able to authenticate and authorize users without interacting with a network authentication server. 8.4.6.2 RADIUS and TACACS+ RADIUS and TACACS+ are security protocols used to authenticate users by means of an external server instead of (or in addition to) an internal device user database that is limited to the memory capacity of the device. In essence, RADIUS and TACACS+ authentication both allow you to validate an unlimited number of users from a central location. ENC User's Guide 225
