Device discovery

What is device management and how does it work

Device discovery is the process where NSP is provided with the management IP address of a supported device, establishes communication with the device, and adds the device to the network. Once the device has been discovered, it becomes a managed device.

NSP supports two main types of device discovery and management:

Model-driven management (MDM) is how NSP manages Nokia and multivendor devices. Device support is provided by adaptors installed in the NSP that provide mediation between certain NSP functions and Nokia/third-party node database models that defines the object and parameter structure of the device.
Classic management is provided by the optionally deployable NSP component, NFM-P. Classic devices are discovered in the NSP and managed by the NFM-P in the background. To ensure alignment between NSP and NFM-P, Nokia recommends that all management operations be performed in the NSP.

Discovery rules

Discovery rules define the protocols and IP address ranges used that NSP uses in device discovery. A “unified” discovery rule supports the discovery of both MDM and classic devices, allowing you to perform both types of discovery with a single configuration form. Discovery of classic devices is provided by a linking between the unified rule and a previously-defined classic discovery rule. The classic discovery rule contains the mediation and reachability policy information required to discover and manage the classic devices in the specified IP address ranges.

See Device discovery procedures for procedures on creating the policies required to discover devices.

Discovering devices in Enterprise NSP

Discovering devices uses the following workflow:

Create a list of devices to be managed and record their management IP addresses for use in a discovery rule.
Create a unified discovery rule and set the Admin State of the discovery rule to “Up”. See Creating a unified discovery rule
Verify the management state of devices. See Viewing managed devices.

Use subject to agreed restrictions on disclosure and use.
