Uploading DMI Schemas


Each device type is described by a unique data model (DM) that contains all the configuration data for the device type. The DMI schema lists all the possible fields and attributes for a type of device. The later schemas describe the new features of recent device releases. It is important that you load all your device schemas into Junos Space Network Management Platform; otherwise, only a default schema is applied when you try to edit a device configuration by using the device configuration edit action in the Devices workspace.

In most installations, Junos Space automatically matches DMI schemas to device families. However, 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 instances, you must obtain and upload the requisite schema and set that schema as the default DMI schema for that device family. Set a default DMI schema for each device family to enable Junos Space to apply the appropriate schema to a device family.

For each of the Cross Provisioning Platform (CPP) release, we recommend that you use the corresponding schema. For example, if you are installing Cross Provisioning Platform Release 14.3, you must download Release 14.3 schema. You can download the schema from Schema Repository.

If you cannot find the equivalent schema, use the latest schema from the main release or contact Juniper Support System (JSS).

To install or update a DMI schema on Junos Space:

  1. From the Network Application Platform, navigate to Administration > Manage DMI Schemas > Update Schema.

    The Update Schema page appears.

    To add or update a DMI schema, you must have the .tgz archive files containing the schema on the machine running the Junos Space GUI. There are several ways of acquiring such files.

    You can:

    • Download files from Juniper Networks SVN repository

    • Obtain files from JSS

    • Create your own files

    For detailed steps on acquiring and uploading the schema files, see Junos Space Documentation or Managing DMI Schemas Overview.

  2. After uploading the schema, select the schema and click Install.

    The Manage DMI Schemas inventory landing page appears, displaying the newly installed schema. The Manage DMI Schemas page displays data in a table that contains the following columns:

    • Device Family—Type of device family

    • OS Version—Version of Junos OS

    • Device Series—Type of Juniper Networks device

    • State—Whether default or not. An empty cell in this column means that the DMI schema in that row is not the default.

      In the thumbnail view, this information is displayed on each thumbnail.

  3. In the tabular view, select the row that contains the appropriate combination of device family, OS version, and device series, and mouse over the Actions menu to select Set Default Schema.

    In the thumbnail view, select the appropriate thumbnail and perform the same action.

    The Set Default DMI Schema dialog box opens, displaying the DMI schema name, device family, and OS version.

  4. Click Set Default.

    If any other schema was previously the default, in the tabular view, the cell in the State column appears empty, and the word Default appears in the State column for the selected schema. In the thumbnail view, the default status is indicated by an orange-colored asterisk on the icon for a DMI schema, and the word Default below the OS version.
