• Default Policy
The Global Default Policy specifies:
– A topology to use when a VNS is created using a policy that does not specify a topology
– A set of filters
The SCALANCE IWLAN Controller ships from the factory with a default “Global Default
Policy” that has the following settings:
– Topology is set to an Bridged at AP untagged topology. This topology will itself be
defined in SCALANCE IWLAN Controllers by default.
– Filters - A single “Allow All” filter.
The Global Default Policy is user-configurable. Changes to the Global Default Policy
immediately effect all shadow policies created from it, just as if the administrator had made a
comparable change directly to the incomplete policy.
• Egress Filtering Mode
The global egress filtering mode setting overrides the individual WLAN service egress filter
mode setting.
• Sync Summary
The “Sync Summary” screen provides an overview of the synchronization status of paired
controllers. The screen is divided into 4 sections: Virtual Networks, WLAN services, Policies
and Topologies. Each section lists the name of the corresponding configuration object, its
synchronization mode, and the status of last synchronization attempt. For more information,
see “Using the Sync Summary” on page 7-19.
Defining RADIUS Servers and MAC Address Format
The Authentication global settings include configuring RADIUS servers, the MAC format to be
used, the SERVICE-TYPE attribute in the client ACCESS-REQUEST messages, and how long a
notice Web page displays if a topology change occurs during authentication. The notice Web page
indicates that authentication was successful and that the user must restart the browser to gain
access to the network.
Defining RADIUS Servers for VNS Global Settings
To Define RADIUS Servers for VNS Global Settings:
1. From the top menu, click VNS Configuration. The Virtual Network Configuration screen is
displayed.
2. In the left pane, click Global, then Authentication.
