DMI Schema Overview
Each device type is described by a unique data model that contains all the configuration data for that device. The schemas for this data model list all the possible fields and attributes for a type of device. The newer schemas describe the new features associated with recent device releases.
Junos Space Network Management Platform provides support for managing devices based on Device Management Interface (DMI) schema.
You must 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 using the device configuration edit action in the Devices workspace (as described in Modifying the Configuration on the Device in the Junos Space Network Management Platform Workspaces User Guide).
If the Junos Space Network Management Platform contains exactly the right schema for each of your devices, you can access all the configuration options specific to each device. You can add or update schemas for all Junos Space devices from the Administration workspace (Administration > DMI Schemas) workspace. You can use this workspace to check whether a schema for a device is missing. On the Manage DMI Schemas page, in tabular view, the DMI Schema column displays Need Import if the Junos OS schema for that particular device OS is not bundled with the Junos Space Network Management Platform. Then you need to download the schema from the Juniper Schema Repository.
