Figure 5-92 RADIUS Based QoS Configuration
To establish a connection with the BSU, the SU sends a registration request to BSU. On receiving the registration request, the
BSU sends an Access request along with the SU MAC address, to the RADIUS Server. The RADIUS Server then checks the
authentication of the user. If it is an authenticated user, it sends an Access-Accept response along with Vendor assigned QoS
parameter’s value to the BSU. On receiving the response, the BSU sends the response to the SU. The received QoS parameters
are then applied on the SU.
Given below are the vendor specific attributes: 
:
RADIUS Based QoS configuration takes priority over Local QoS configuration.
When the link is down, the configuration received from the RADIUS is lost.
5.8 VLAN (Bridge Mode Only)
The Virtual Local Area Network (VLAN) feature helps in logical grouping of network host on different physical LAN segments,
which can communicate with each other as if they are all on the same physical LAN segment. 
With VLANs, you can conveniently, efficiently, and easily manage your network in the following ways:
Define groups
Limits the broadcast and multicast traffic to a specific VLAN group
– Improve network performance and reduce latency
Increase security
– Secure network restricts members to resources on their own VLAN
The SUs and End Point devices support QinQ VLAN feature that enables service providers to use a single VLAN ID to support
multiple customer VLANs by encapsulating the 802.1Q VLAN tag within another 802.1Q frame. The benefits with QinQ are,
