Junos Space SDG DMI Schema Requirements for Junos Space Edge Services Director


In most installations, Junos Space automatically matches DMI schemas to device families. But there might be certain situations where your network uses a device for which Junos Space does not have the latest or supported schema available. In such situations, you must obtain and upload the requisite schema and set it as the default DMI schema for each device family. For the service delivery gateways (SDGs), which are running on MX Series routers, you can set a default SDG DMI schema for each device family to enable Junos Space to apply an appropriate schema to a device family.


See Setting a Default DMI Schema for detailed steps to set a default schema.

Table 1 lists the latest SDG DMI schema that you must obtain and upload in Junos Space before you start working on Edge Services Director Release 1.1.

After you obtain the DMI schema, to install the schema update on Junos Space Platform if you already have the compressed TAR file (extension .tgz) available:

  1. On the Junos Space Network Management Platform user interface, select Administration > DMI Schemas

    The DMI Schemas page appears.

  2. Click the Update Schema icon on the toolbar.

    The Update Schema page appears.


    On the Update Schema page, Junos Space Platform displays the schemas that you already have installed and, based on the discovered devices, suggests new schemas. However, you can pick other available schemas and download them.

  3. Select the Archive (tgz) option button.
  4. Click Browse.

    The File Upload dialog box appears.

  5. Select the compressed TAR file (extension .tgz) and click Open.

    The Update Schema page reappears, displaying the compressed TAR file (extension .tgz) in the Archived Schemas File field.

  6. Click Upload.Note

    Do not move away from the Update Schema page while the compressed TAR file (extension .tgz) is being uploaded to Junos Space Platform. The time taken for the upload process depends on the number of schemas in the file. A progress bar indicates the percentage of the upload that has completed.

To update the DMI schema directly from the Juniper Networks DMI schema repository:

  1. Select the SVN Repository option button.

    If the access to the Juniper Networks Subversion repository is already configured, the URL of the repository is displayed in the URL field. If the access is not configured, a note indicating that the access must be configured is displayed.

    To configure access to the Juniper Networks Subversion repository:

    1. Click Configure.

      The SVN Access Configuration dialog box appears.

    2. In the Svn URL field, enter the URL of the Juniper Networks Subversion repository (
    3. In the User Name field, enter the user name to access the Juniper Networks Subversion repository.
    4. In the Password field, enter the password to access the Juniper Networks Subversion repository.
    5. In the Confirm field, reenter the password to access the Juniper Networks Subversion repository.
    6. (Optional) The Proxy Server field displays whether a proxy server is configured or not. If your organization requires that you use a proxy server to connect to the Internet, you must configure and enable the proxy server (under Administration > Proxy Server) before connecting to the Juniper Networks Subversion repository.

      (Optional) Click Test Connection.

      A message dialog box appears (after a few seconds or a few minutes depending on the connection) to indicate whether the connection is established successfully or not. Click OK to close the dialog box and return to the Svn Access Configuration dialog box.

    7. Click Save to save the settings that you configured.

      You are taken to the Update Schema page and the URL that you configured is displayed in the URL field.

  2. (Optional) From the Device Family drop-down list, select the device families that you want to download from the repository.Note

    If you do not specify a device family, then available schemas from all families are listed.

  3. Click Connect.

    Junos Space Platform displays a message asking you to wait while the list of schemas is retrieved. (This process might take anywhere from a few seconds to a few minutes depending on the connection.)
