Thedevice selects the NAS-ID for the NAS-Identifier attribute in the following order:1. NAS-ID bound with VLANs in a NAS-ID profile.2. NAS-ID on an interface.3. NAS-ID in an ISP domain.If no NAS-ID is selected, the device uses the device name (set by using the sysname command) asthe NAS-ID.Configuring a NAS-ID profileConfigure a NAS-ID profile to maintain NAS-ID and VLAN bindings on the device so that the devicecan send different NAS-Identifier attribute strings in RADIUS requests from different VLANs.You can apply a NAS-ID profile to portal-enabled interfaces. For more information, see "Configuringportal authentication."A NAS-ID can be bound with more than one VLAN or one combination of inner VLAN and outerVLAN.
