96 Update with your book titleAdvanced 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-sessionaccess. Only one host must be authorized for all hosts to access the network. If the host authenticationfails 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 networkaccess via port-based authorization, but the Guest VLAN is enabled, the port receives limited networkaccess. For example, a network administrator can use Guest VLANs to deny network access via port-based authentication, but grant Internet access to unauthorized users.To open the Network Security page select Switch → Network Security.Configuring Port Based AuthenticationThe Port Based Authentication page contains fields for configuring port based authentication and forenabling Guest VLANs.
