Enable the selected ports as authenticators and enable the (default) port-based authentication


[no] aaa port-access authenticator <port-list>

Enables specified ports to operate as 802.1X authenticators and enables port-based authentication. (To enable user-based authentication, execute this command first, and then execute the client-limit <port-list> version of this command described in the next section.) The no form of the command removes 802.1X authentication from <port-list>. To activate configured 802.1X operation, you must enable 802.1X authentication. See Enable 802.1X authentication on the switch.
