Advanced Port Based Authentication is implemented in the following modes: • Single Host Mode - Enables only the authorized host for single-session access to the port. • Multiple Host Mode - Enables multiple hosts to be attached to a single port, for single-session access. 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. • Multiple Session Mode - Enables only the authorized host for multiple-session access to the port. • Guest VLANs - Provides limited network access to unauthorized ports. If a port is denied network access via port-based authorization, but the Guest VLAN is enabled, the port receives limited network access. For example, a network administrator can use Guest VLANs to deny network access via portbased authentication, but grant Internet access to unauthorized users.
