The device currently supports Port Based Authentication via RADIUS servers.
Advanced Port Based Authentication
Advanced Port Based Authentication enables multiple hosts to be attached to a single port.
Advanced Port Based Authentication requires only one host to be authorized for all hosts to have
system access. If the port is unauthorized all attached hosts are denied access to the network.
Advanced Port Based Authentication also enables user based authentication. Specific VLANs in the
device are always available, even if specific ports attached to the VLAN are unauthorized. For
example, Voice over IP does not require authentication, while data traffic requires authentication.
VLANs for which authorization is not required can be defined. Unauthenticated VLANs are
available to users, even if the ports attached to the VLAN are defined as authorized.
Advanced Port Based Authentication is implemented in the following modes:
•
Single Host Mode
— Enables only the authorized host to access the port.
•
Multiple Host Mode
— Enables multiple hosts to be attached to a single port. Only one host
must be authorized for all hosts to access the network. If the host authentication fails or an
EAPOL-logoff message is received, all attached clients are denied network access.
