234 Configuring Switch Information

Advanced Port Based Authentication also enables VLAN based authentication. Specific VLANs in
the switch 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.
