WEP.
What is the difference between No authentication required, No access allowed and
Authentication required?
No authentication required—disables IEEE 802.1X and causes the port to transition to the authorized
state without any authentication exchange required. The port transmits and receives normal traffic without
IEEE 802.1X-based authentication of the client.
No access allowed—causes the port to remain in the unauthorized state, ignoring all attempts by the client
to authenticate. The device cannot provide authentication services to the client through the interface.
Authentication required—enables IEEE 802.1X and causes the port to begin in the unauthorized state,
allowing only EAPOL frames to be sent and received through the port. The authentication process begins
when the link state of the port transitions from down to up, or when an EAPOL-start frame is received.
The device requests the identity of the client and begins relaying authentication messages between the
client and the authentication server. Each client attempting to access the network is uniquely identified by
the device by the client's MAC address.
What is AAA?
AAA (Authentication, Authorization, and Accounting) refers to the idea of managing subscribers by
controlling their access to the network, verifying that they are who they say they are (via login names and
passwords or MAC addresses) and accounting for their network usage.

What is RADIUS?

RADIUS (Remote Authentication Dial-In User Service) is a standard that has been implemented into
several software packages and networking devices. It allows user information to be sent to a central
database running on a RADIUS Server, where it is verified. RADIUS also provides a mechanism for
accounting.
What is WPA?
WPA (Wi-Fi Protected Access) is a subset of the IEEE 802.11i security specification draft. Key
difference between WPA and WEP are user authentication and improve data encryption.

What is WPA-PSK?
