Virtual Delivery Agent policy settings

May 10, 2015

The Virtual Delivery Agent (VDA) section contains policy settings you can configure to control communication between the VDA and controllers for a site.

Important: The VDA requires information provided by these settings to register with a controller, if you are not using the auto-update feature. Because this information is required for registration, you must configure the following settings using Active Directory's Group Policy Editor, unless you provide this information during the VDA install:
  • Controller registration IPv6 netmask
  • Controller registration port
  • Controller SIDs
  • Controllers
  • Only use IPv6 controller registration
  • Site GUID

Controller registration IPv6 netmask

This policy setting allows administrators to restrict the VDA to only a preferred subnet (rather than a global IP, if one is registered). This setting specifies the IPv6 address and network where the VDA will register. The VDA will register only on the first address that matches the specified netmask. This setting is valid only if the Only use IPv6 controller registration policy setting is enabled.

By default this setting is blank.

Controller registration port

Use this setting only if the Enable auto update of controllers setting is disabled.

This setting specifies the TCP/IP port number the VDA uses to register with a controller, when using registry-based registration.

By default, the port number is set to 80.

Controller SIDs

Use this setting only if the Enable auto update of controllers setting is disabled.

This setting specifies a space-separated list of controller Security Identifiers (SIDs) the VDA uses to register with a controller, when using registry-based registration. This is an optional setting, that may be used in conjunction with the Controllers setting, to restrict the list of controllers used for registration.

By default, this setting is blank.

Controllers

Use this setting only if the Enable auto update of controllers setting is disabled.

This setting specifies a space-separated list of controller Fully Qualified Domain Names (FQDNs) the VDA uses to register with a controller, when using registry-based registration. This is an optional setting, that may be used in conjunction with the Controller SIDs setting.

By default, this setting is blank.

Enable auto update of controllers

This setting enables the VDA to register with a controller automatically after installation.

After the VDA registers, the controller with which it registered sends a list of the current controller FQDNs and SIDs to the VDA. The VDA writes this list to persistent storage. Each controller also checks the site database every 90 minutes for controller information; if a controller has been added or removed since the last check, or if a policy change has occurred, the controller sends updated lists to its registered VDAs. The VDA will accept connections from all the controllers in the most recent list it received.

By default, this setting is enabled.

Only use IPv6 controller registration

This setting controls which form of address the VDA uses to register with the controller:
  • When enabled, the VDA registers with the controller using the machine's IPv6 address. When the VDA communicates with the controller, it uses the following address order: global IP address, Unique Local Address (ULA), link-local address (if no other IPv6 addresses are available).
  • When disabled, the VDA registers and communicates with the controller using the machine's IPv4 address.

By default, this is setting is disabled.

Site GUID

Use this setting only if the Enable auto update of controllers setting is disabled.

This setting specifies the Globally Unique Identifier (GUID) of the site the VDA uses to register with a controller, when using Active Directory-based registration.

By default, this setting is blank.

HDX 3D Pro policy settings

The HDX 3D Pro section contains policy settings for enabling and configuring the image quality configuration tool for your users. The tool enables users to optimize their use of the available bandwidth by adjusting in real time the balance between image quality and responsiveness.

Enable lossless

This setting specifies whether or not users can enable and disable lossless compression using the image quality configuration tool. By default, users are not given the option to enable lossless compression.

When a user enables lossless compression, the image quality is automatically set to the maximum value available in the image configuration tool. By default, either GPU or CPU-based compression can be used, according to the capabilities of the user device and the host computer.

HDX 3D Pro quality settings

This setting specifies the minimum and maximum values that define the range of image quality adjustment available to users in the image quality configuration tool.

Specify image quality values of between 0 and 100, inclusive. The maximum value must be greater than or equal to the minimum value.
