DMI Schema Compatibility for Junos OS Service Releases

The following tables explain how the Junos Space Network Management Platform chooses Device Management Interface (DMI) schemas for devices running Junos OS Service Releases.

If a Junos OS Service Release is installed on your device with a major release version of a DMI schema installed on Junos Space Network Management Platform, then Junos Space chooses the latest corresponding major release of DMI schemas, as shown in Table 1.

Table 1: Device with Service Release and Junos Space with FRS Release

Junos OS Version on Device	Junos Space DMI Schemas Installed	Junos Space Default Version	Junos Space Version Chosen for Platform
18.4R1-S1	18.4R1.8 18.3R1.1 18.2R1.1	18.2R1.1	18.4R1.8
If 18.4R1.8 version is not available, then Junos Space chooses the nearest lower version of DMI schema installed.
18.4R1-S1	18.3R1.1 18.2R1.1	18.2R1.1	18.3R1.1

If a Junos OS Service Release is installed on your device without a matching DMI schema version in Junos Space Network Management Platform, then Junos Space chooses the nearest lower version of DMI schema installed, as shown in Table 2.

Table 2: Device with Service Release and Junos Space without matching DMI Schema

Junos OS Version on Device	Junos Space DMI Schemas Installed	Junos Space Default Version	Junos Space Version Chosen for Platform
18.4R1-S1	18.5R1.1 18.3R1.1 18.2R1.1	18.2R1.1	18.3R1.1

If more than one version of the DMI schemas are installed in Junos Space Platform for a single Junos OS Service Release version, Junos Space chooses the latest version of the DMI schema, as shown in Table 3.

Table 3: Device with Service Release and Junos Space with more than one DMI Schemas

Junos OS Version on Device	Junos Space DMI Schemas Installed	Junos Space Default Version	Junos Space Version Chosen for Platform
18.4R1-S1	18.4R1.8 18.4R1.7 18.4R1.6 18.3R1.1	18.3R1.1	18.4R1.8
If 18.4R1.x versions are not available, then Junos Space chooses the nearest lower version of DMI schema installed.
18.4R1-S1	18.3R1.1 18.2R1.1	18.2R1.1	18.3R1.1

If a Junos OS Service Release is installed on your device without a corresponding DMI schema version in Junos Space Network Management Platform, then Junos Space chooses the nearest lower version of DMI schema installed, as shown in Table 4.

Table 4: Device with Service Release and Junos Space without more DMI Schemas
