that is running on the managed devices. NSM uses capability files to enable JUNOS
software upgrades without changing the device configuration in NSM.
The M-series and MX-series device families are described by schemas that are maintained
on a schema repository owned by Juniper Networks. These schemas can be added
dynamically to NSM.

The M-series and MX-series devices and the NSM application communicate through the
Device Management Interface (DMI). DMI is a collection of schema-driven protocols that
run on a common transport (TCP). DMI is designed to work with routers running the
JUNOS software to make device management consistent across all administrative realms.
The DMI protocols that are supported include NetConf (for inventory management,
XML-based configuration, text-based configuration, alarm monitoring, and device-specific
commands), structured syslog, and threat flow for network profiling. DMI supports
third-party network management systems that incorporate the DMI standard; however,
only one DMI-based agent per device is supported.
The configuration of the M-series and MX-series device is represented as a hierarchical
tree of configuration items. This structure is expressed in XML that can be manipulated
with NetConf. NetConf is a network management protocol that uses XML. DMI uses
NetConf's generic configuration management capability and applies it to allow remote
configuration of the device.
The schema repository enables access to XSD and XML files defined for each device,
model, and software version.
