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.
