3.5.5.7 Advanced VLAN Capabilities
The Quantum Base Station has advanced Virtual LAN (or VLAN) capabilities as defined by IEEE 802.1q and
802.1p. The VLAN tags are a numerical header applied to an Ethernet frame in order to segregate a
physical Ethernet segment into logical networks. The advantages of using a VLAN are the following:
• Quality of Service (Qos) capabilities at Layer 2 allows different types of traffic to be placed on
different VLANs for segmentation. E.g. Voice, video and data traffic can be assigned different
VLANs
• Security to isolate user traffic from each other and keep management traffic separate
• Network Optimization to reduce broadcast storms and end user devices affecting the entire
network.
3.5.5.8 VLAN for Management Traffic
VLAN Management may be configured on the Base Station. Care must be taken to ensure this is
configured correctly. All management traffic will accept management VLAN only including the Web GUI,
FTP, SNMP, Telnet, Radius, SSH, R6 Control path and NTP. See section 3.5.3.5 for further information on
configuring the management VLAN.
3.5.5.9 VLAN for Data Traffic
In order to configure VLAN operations, the Base Station must be configured in Ethernet CS – Stand
Alone Mode. There are three modes of operation available that are configured from the VLAN profile.
• Transparent mode where the CPE (or devices behind the CPE) are performing tagging and
untagging
• Per CPE Basis (per-mss) where a specific VLAN ID is assigned to a specific CPE from the Base
Station side. On the CPE side there is no device with VLAN support, and this is transparent to
the user.
• Service Flow (per-sf) basis where individual service flows are assigned a specific VLAN ID. This is
useful for enforcing QoS policies and requires advanced configuration, classification and
planning for implementation.
