Virtual Network configuration
VNS Types
6 Virtual Network configuration
This chapter discusses VNS (Virtual Network Services) configuration, including:
• Topology for a VNS
• Assigning Wireless AP radios to a VNS
• Authentication for a VNS
• Defining accounting methods for a VNS
• Defining RADIUS filter policy for VNSs and VNS groups
• Configuring filtering rules for a VNS
• Enabling multicast for a VNS
• Configuring privacy for a VNS
• Defining a VNS with no authentication
• Defining priority level and service class for VNS traffic
• Working with Quality of Service (QoS)
• Configuring the QoS policy on a VNS
• Bridging traffic locally
• Wireless Distribution System
Setting up a VNS defines a virtual IP subnet for a group of wireless device users,
where the HiPath Wireless Controller acts as a default gateway to wireless
devices. For each VNS, you define its topology, authentication, accounting,
RADIUS servers, filtering, multicast parameters, privacy and policy mechanism.
When you set up a new VNS, additional tabs appear only after you save the
topology.
6.1 VNS Types
The VNS topologies are classified on the basis of the following VNS types:
• Routed VNS – User traffic is tunneled to the HiPath Wireless Controller. (This
is the default setup.)
• Bridged at the AP VNS – User traffic is directly bridged to a VLAN at the AP
network point of access (switch port).
• VLAN bridged VNS – User traffic is tunneled to the HiPath Wireless
Controller and is directly bridged at the controller to a specific VLAN. With this
VNS type, mobile users become a natural extension of a VLAN subnet.
