and auto ?
force-authorized
—disables 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 802.1X-based authentication of
the client.
force-unauthorized
—causes the port to remain in the unauthorized state,
ignoring all attempts by the client to authenticate. The switch cannot provide
authentication services to the client through the interface.
auto
—enables 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 switch 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 switch by using the client's MAC address.
13. What is AAA ?
AAA is the acronym for Authentication, Authorization, and Accounting and
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 name and
password or MAC address) and accounting for their network usage.
14. What is RADIUS ?
RADIUS stands for Remote Authentication Dial-In User Service. RADIUS 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.
