untagged per AP per radio. The other branch mode VNSs need to have
unique VLAN ID. You must have VLAN aware L2 switches to support this
feature.
Note: When a VNS is setup for bridged mode, it cannot be switched to
tunneled mode. The administrator must delete and re-add the VNS.
6.17 Wireless Distribution System
A Wireless Distribution System (WDS) enables you to expand the wireless
network by interconnecting the Wireless APs through wireless links in addition to
the traditional method of interconnecting Wireless APs via a wired network.
Note: The HiPath Wireless 802.11n AP and the Scalance AP W788-2 do not
support WDS.
A WDS deployment is ideally suited for locations, where installing ethernet
cabling is too expensive, or physically impossible.
The WDS can be deployed in three configurations:
• Simple WDS Configuration
• Wireless Repeater Configuration
• Wireless Bridge Configuration
6.17.1 Simple WDS configuration
In a typical configuration, the Wireless APs are connected to the distribution
system via an Ethernet network, which provides connectivity to the HiPath
Wireless Controller.
However, when a Wireless AP is installed in a remote location and can’t be wired
to the distribution system, an intermediate Wireless AP is connected to the
distribution system via the Ethernet link. This intermediate Wireless AP forwards
and receives the user traffic from the remote Wireless AP over a radio link.
The intermediate Wireless AP that is connected to the distribution system via the
Ethernet network is called Root AP, and the Wireless AP that is remotely located
is called the Satellite AP.
The following figure illustrates the Simple WDS configuration:
