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 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.
