You select your desired mode by using the Security Databases pop-up menu.

Choosing Local Only, the default, selects the pre-4.8 authentication mechanism.

Choosing RADIUS Only causes the router to ignore the local database and to authenticate users using the configured RADIUS server.

Choosing RADIUS then Local causes the router to attempt to authenticate a user first using a RADIUS server and then, if that fails, using the local authentication database.

Choosing Local then RADIUS causes the router to attempt to authenticate a user first using the local authentication database, and then, if that fails using the configured RADIUS server.

Note: In the latter two modes that involve both RADIUS and the local database, if the local database includes no username/password pairs, authentication will succeed only if the RADIUS server authenticates the user. This differs from the Local Only mode where no authentication is performed when the local database is empty.

If the primary RADIUS server responds with an access rejection or an access challenge, the alternate RADIUS server is not contacted. Only if the primary RADIUS server fails to respond at all is the alternate RADIUS server contacted.

Therefore, do not attempt to select any of the RADIUS options unless you have a RADIUS server correctly configured for this purpose. If you attempt to use RADIUS authentication without a RADIUS server, you will lose your configuration access to the router.

The Advanced Security Options screen supports both a primary RADIUS server and an alternate RADIUS server. When the router is configured to authenticate using RADIUS, it will first attempt to contact the primary RADIUS server; if the primary RADIUS server responds, RADIUS authentication succeeds or fails based on the response returned by the primary server. If and only if the primary server fails to respond, the router will attempt to contact the alternate RADIUS server to authenticate the user. The router makes two attempts per server, three seconds apart.

You can specify the RADIUS Server Addr/Name and the Alt RADIUS Server Addr/Name either by using a
