Figure 1-2 Authorized/unauthorized status of a controlled port
You can set the authorization mode of a specified port to control the port authorization status. The
authorization modes include:
z
authorized-force : Places the port in the authorized state, allowing users of the ports to access the
network without authentication.
z
unauthorized-force : Places the port in the unauthorized state, denying any access requests from
users of the ports.
z
auto : Places the port in the unauthorized state initially to allow only EAPOL packets to pass, and
turns the ports into the authorized state to allow access to the network after the users pass
authentication. This is the most common choice.
Control direction
In the unauthorized state, the controlled port can be set to deny traffic to and from the client or just the
traffic from the client.
Currently, your device can only be set to deny traffic from the client.
EAP over LAN
EAPOL packet format
EAPOL, defined in 802.1X, is intended to carry EAP protocol packets between clients and devices over
