Configuring Port Based Authentication - Dell PowerConnect 2808 User Manual

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 port-
based authentication, but grant Internet access to unauthorized users.
