Explanation:
Enabling 802.1X Authentication
To enable 802.1X port-based authentication, you must enable AAA and specify the
authentication method list. A method list describes the sequence and authentication
methods to be queried to authenticate a user.
The software uses the first method listed to authenticate users; if that method fails to
respond, the software selects the next authentication method in the method list. This process
continues until there is successful communication with a listed authentication method or until
all defined methods are exhausted. If authentication fails at any point in this cycle, the
authentication process stops, and no other authentication methods are attempted.
Beginning in privileged EXEC mode, follow these steps to configure 802.1X port-based
authentication. This procedure is required.
