Virtual Network Services concepts
VNS overview
5 Virtual Network Services concepts
This chapter introduces and describes the concept of Virtual Network Services
(VNS), including:
VNS overview
Setting up a VNS checklist
NAC integration with HiPath WLAN
Wireless AP assignment to WLAN Services
Authentication for a VNS
Filtering
Multicast traffic
Data protection — WEP and WPA
QoS Policy
Flexible Client Access (FCA)
5.1 VNS overview
Starting with Release V7.0, the VNS concept is factored into two main
components:
WLAN Service - which defines the radio/RF attributes of a service (e.g. its
SSID), its privacy and authentication settings and the QoS attributes.
User Policy - which defines the topology (typically a VLAN), filter rules, and
Class of Service applied to the traffic of a station.
Rather than being a collection of operational entities, a VNS becomes simply the
binding between the WLAN service and the user policy for default operation. The
policy assignment ensures that the correct topology and traffic behavior are
applied to a user regardless/independent of the SSID.
This new representation model extends provisioning functionality by allowing for:
Multiple WLAN services associated to the same Topology (VLAN
Mapping)
Overlapped Role/Policy Assignment
User to policy association independent of access SSID
Separation of L2/L3 representations
