VNS Global Settings

Before defining a specific VNS, define the global settings that apply to all VNS definitions. These global settings include:

• Authentication
  • Configuring RADIUS servers on the enterprise network. The defined servers are displayed as available choices when you set up the authentication mechanism for each WLAN (Wireless Local Area Network) Service.
  • Configuring the MAC format.
  • Configuring RFC 3580 (ACCESS -ACCEPT) RADIUS attributes for the selected server. A Role Map Table maps each VLAN (Virtual LAN) ID to a Role ID.
• DAS (Dynamic Authorization Service)
  • Configuring Dynamic Authorization Service (DAS) support. DAS helps secure your network by providing the ability to disconnect a mobile device from your network.
• Wireless QoS, comprising Admission Control Thresholds and Flexible Client Access Fairness Role.
  • Admission control thresholds protect admitted traffic against overloads, provide distinct thresholds for VO (voice) and VI (video), and distinct thresholds for roaming and new streams.
  • Flexible Client Access provides the ability to adjust media access fairness in five levels between Packet Fairness and Airtime Fairness.
• Bandwidth Control
  • The Bandwidth Control Profiles you define are displayed as available choices in the Rate Profiles menu when you set up CoS (Class of Service) role.
• Default Role

  The Global Default Policy specifies:

  • A topology to use when a VNS is created using a role that does not specify a topology
  • A set of filters

    The 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 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 roles created from it, just as if the administrator had made a comparable change directly to the incomplete role.

• Egress Filtering Mode

  The global Egress Filtering Mode setting overrides the individual WLAN service Egress Filtering Mode setting.

• Sync Summary

  The Sync Summary screen provides an overview of the synchronization status of paired controllers. The screen is divided into sections: Virtual Networks, WLAN services, Roles, 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.

• NAC Integration

  NAC Integration provides a list of NAC servers for use by the controller for passing DHCP (Dynamic Host Configuration Protocol) traffic. The NAC server can accept DHCP messages from the controller‘s DHCP server and use them to fingerprint devices. For more information, see Using NAC Integration.

• Client Auto Login

  This features configures how auto login behavior is handled for users with devices that need to authenticate to a captive portal to gain network access. For more information, see Using Client Login.

• Topology Group Algorithm

  Topology Group Algorithms are used for selecting a member Topology from a Topology Group. The wireless controller will run one of the following algorithms: MAC based, Round Robin, Random Selected, and Lease used. For more information, see Using Topology Group Algorithm.

• Netflow/MirrorN

  Use Netflow to forward packet information. Integration with ExtremeAnalytics no longer requires Netflow/MirrorN. See ExtremeAnalytics Support with Enhanced IPFIX Records for more information.

• Redirection URL
  Configure a list of redirection URLs from the Redirection URL dialog. You can add and delete a URL.

  

  Note

  To display the Redirection URL option, enable Rule-based Redirection under Filtering Mode.
