3.6 Virtual LAN (VLAN) Configuration
A Virtual Local Area Network or VLAN is a switched network that has been segmented by function or
application rather than by the traditional LAN segmentation which is based on physical location. VLANs
allow a greater level of flexibility than a standard LAN, and enable changes to be made to the network
infrastructure without physically disconnecting network equipment. The WS2000 Wireless Switch supports
assigning one VLAN ID to each of the configured subnets.
To configure one or more VLANs, select Network Configuration --> VLAN from the navigation menu on
the left. The VLAN Configuration screen appears.
The upper part of the screen is used to set up the VLAN type to be created.
1. Use the pull-down menu to select a VLAN Type for this switch. The two options available are User Based
and Port Based.
Port-based VLANs partitions traffic based on port on which the packet is received. The switch inspects
each packet, extracts the port on which it was received (from control information provided by the driver)
and processes the packet based on the port. The port is mapped to a subnet and each subnet is mapped
to a single VLAN. The switch processes the packet based on this mapping.
User-based VLAN traffic classification is performed only for Wireless traffic. The VLAN for a particular
MU is identified when the MU authenticates itself with the RADIUS server using a user ID and password.
The RADIUS server provides the VLAN ID corresponding to this MU and User ID information combination.
The switch processes the packet based on the VLAN ID provided by the RADIUS server.
For wired traffic, the classification as done in Port-based VLANs applies.
2. Use the pull-down menu to select a Trunk Port for the switch. Only the WAN port can be configured as
the Trunk Port.
3. Enter the Default VLAN ID to be used for packets that do not have the VLAN tag inserted. The default
VLAN ID must be one of the IDs assigned to the subnets if the VLAN Type is Port Based. If the VLAN
Type is User Based, then the Default VLAN ID must be one from the Allowed VLANs list.
4. For each enabled Subnet, enter the VLAN ID.
