Usage Guidelines Single-host mode should be configured if only one data host is connected. Do not connect a voice device
to authenticate on a single-host port. Voice device authorization fails if no voice VLAN is configured on
the port.
Multi-domain mode should be configured if data host is connected through an IP Phone to the port.
Multi-domain mode should be configured if the voice device needs to be authenticated.
Multi-auth mode should be configured to allow up to eight devices behind a hub to obtain secured port
access through individual authentication. Only one voice device can be authenticated in this mode if a
voice VLAN is configured.
Multi-host mode also offers port access for multiple hosts behind a hub, but multi-host mode gives
unrestricted port access to the devices after the first user gets authenticated.
