Managing Policies

Scenario

Configure policies such as USB Port RedirectionPrinter RedirectionFile Redirection, and Clipboard Redirection to control the permission on data transmission and peripheral access between user terminals and Workspace.

Procedure

  1. Log in to the Workspace management console.
  1. Click Policy.

    The Policy page is displayed.

  2. On the Policy page, click the following button to enable or disable a policy. Table 1 describes the policies.

    • indicates that the policy is enabled.
    • indicates that the policy is disabled.
      Table 1 Policy management

      Policy Type

      Policy Parameter

      Policy Description

      USB port redirection

      Graphics devices (such as scanners)

      Users can use USB graphics devices by using USB port redirection on desktops.

      Video devices (such as cameras)

      Users can use USB video devices by using USB port redirection on desktops.

      Print devices (such as printers)

      Users can use USB print devices by using USB port redirection on desktops.

      Storage devices (such as USB flash drives)

      Users can use USB storage devices by using USB port redirection on desktops.

      Smartcard devices (such as Ukeys)

      Users can use smartcard devices by using USB port redirection on desktops.

      Printer redirection

      Sync Client Default Printer

      Users can use printers by using printer redirection (a policy of device redirection) on desktops.

      Universal printer driver

      • Default
      • HDP XPSDrv Driver
      • Universal Printing PCL 5
      • Universal Printing PCL 6
      • Universal Printing PS

      When Default is selected, Universal Printing PS will be loaded if printer redirection is enabled on Linux clients, and HDP XPSDrv Driver will be loaded if printer redirection is enabled on Windows clients.

      NOTICE:

      To use the printer service, you need to ensure that all end users use SCs running the same OS to log in to Workspace.

      File redirection

      Fixed Drive (such as local disks)

      Redirects client fixed drives.

      Removable drive (such as USB flash drives)

      Redirects client removable drives, such as USB flash drives and removable hard disks.

      CD/DVD-ROM drives

      Redirects client CD-ROM drives.

      Network Drive

      Redirects client network drives.

      Clipboard redirection

      Server to client

      After the redirection is enabled, end users can copy data on desktops and paste the data on clients. However, data copied on clients cannot be pasted on desktops. That is, the one-way clipboard function from the server to the client is supported.

      Client to server

      After the redirection is enabled, end users can copy data on clients and paste the data on desktops. However, data copied on desktops cannot be pasted on clients. That is, the one-way clipboard function from the client to the server is supported.

      Enable Bidirection

      After the redirection is enabled, end users can copy data on clients and paste the data on desktops, and data copied on desktops can also be pasted on clients. That is, the two-way clipboard function between the client and the server is supported.

      Disable

      Disables the clipboard redirection.

      HDP Plus

      • Enable
      • Disable (default)

      This option only applies to video editing scenarios.

      Display level

      Smoothness first (default)

      Balances display quality and bandwidth requirement. The recommended bandwidth is 20,000 kbit/s.

      Image quality first

      Provides best display quality but requires highest bandwidth. The recommended bandwidth is 25,000 kbit/s.

      Advanced policies

      • Bandwidth
      • Frame Rate
      • Video Frame Rate
      • Smoothing Factor
      • Lossy Compression Quality

      For details about how to set video image quality and smoothness, see Table 2.

      Table 2 Advanced policies

      Policy Name

      Default Value

      Range

      Description

      Bandwidth (kbit/s)

      This policy is available only when the HDP Plus policy is disabled.

      • Smoothness first: 20,000
      • Quality first: 25,000

      1000 to 25,000

      Specifies the data code stream limit. Increasing this value improves user experience but consumes more bandwidth resources. For this reason, if the network bandwidth is insufficient, increasing this value compromises the smoothness.

      The default value is recommended.

      Frame Rate (fps)

      This policy is available only when the HDP Plus policy is disabled.

      • Smoothness first: 25
      • Quality first: 30

      15 to 30

      Specifies the frame rate in non-video scenarios. Increasing this value improves image smoothness but consumes more bandwidth resources. For this reason, if the network bandwidth is insufficient, increasing this value compromises the smoothness.

      The default value is recommended.

      Video Frame Rate (fps)

      This policy is available only when the HDP Plus policy is disabled.

      • Smoothness first: 30
      • Quality first: 50

      15 to 50

      Specifies the video frame rate. Increasing this value improves image smoothness but consumes more bandwidth resources. For this reason, if the network bandwidth is insufficient, increasing this value compromises the smoothness.

      The default value is recommended.

      Smoothing Factor

      This policy is available only when the HDP Plus policy is disabled.

      • Smoothness first: 60
      • Quality first: 60

      0 to 60

      Specifies the static image quality. Decreasing this value improves image quality but consumes more bandwidth resources, and compromises the smoothness.

      Lossy Compression Quality

      • Smoothness first: 85
      • Quality first: 90

      70 to 90

      Specifies the static natural image quality. Increasing this value improves image quality but consumes more bandwidth resources, and compromises the smoothness.

  3. Click Save to save the configured policy information. An end user must relog in to the desktop for the new policy to take effect.
