Figure 1-4 VNS as a Binding of Reusable Components

WLAN Service components and Policy components can be configured separately and associated

with a VNS when the VNS is created or modified. Alternatively, they can be configured during the

process of creating a VNS.

When VNS components are set up on the SCALANCE IWLAN Controller, among other things, a

range of IP addresses is set aside for the SCALANCE IWLAN Controller’s DHCP server to assign

to wireless devices.

If the OSPF routing protocol is enabled, the SCALANCE IWLAN Controller advertises the routed

topologies as reachable segments to the wired network infrastructure. The controller routes traffic

between the wireless devices and the wired network.

The SCALANCE IWLAN Controller also supports VLAN-bridged assignment for VNSs. This

allows the controller to directly bridge the set of wireless devices associated with a WLAN service

directly to a specified core VLAN.

Each SCALANCE IWLAN Controller model can support a specified number of active VNSs, as

listed below:

• WLC711 — Up to 8 VNSs

The Wireless AP radios can be assigned to each of the configured WLAN services and, therefore,

VNSs in a system. Each Wireless AP can be the subject of 16 service assignments — 8 assignments

per radio — which corresponds to the number of SSIDs it can support. Once a radio has all 8 slots

assigned, it is no longer eligible for further assignment.
