If you enable the periodic reauthentication option, in the Reauthentication Period field, enter the period in seconds after which the supplicant must be reauthenticated. Enter a value in the range from 0 to 65535. The default is 3600 seconds. 22. From the User Privileges menu, select admin or guest to limit the type of users that can be granted access. By default, both admin and guest users can be granted access. 23. In the Max Users field, enter the maximum number of supplicants that the interface can support. The default is 48. 24. In the Authentication Order columns, enter the order in which authentication must occur for up to three methods: • Method 1: The default selection is DOT1X. The other options are MAB, and CAPTIVE PORTAL. You cannot disable Method 1. • Method 2: The default selection is MAB. The other options are None, DOT1X, and CAPTIVE PORTAL. Disable Method 2 by selecting None. • Method 3: The default selection is CAPTIVE PORTAL. The other options are None, DOT1X, and MAB. Disable Method 3 by selecting None. As an example, if a client tries 802.1X authentication (based on the user and client credentials) and authentication fails, the interface proceeds with MAB authentication. If that method fails too, the interface proceeds with captive portal authentication. If that method fails too, the client cannot be authenticated. 25. Click the Apply button.
