How do I discover devices?

Purpose

To discover devices, create a unified discovery rule. NSP performs scans of the network to look for devices matching specifications provided in active discovery rules. You can also launch a discovery manually.

The association of a classic discovery rule provides information for discovery of classic devices. The discovery protocols and policies parameters in the discovery rule provide information for discovery and management of MDM devices. When associating a classic discovery rule from NFM-P to a unified discovery rule, verify that the list of IP addresses in the unified discovery rule matches the list of IP addresses from the NFM-P classic discovery rule.

RESTCONF APIs are also available for device discovery and management; see the Device Administration and Mediation RESTCONF APIs documentation on the Network Developer Portal.

Steps
 

Open Device Discovery, Unified Discovery Rules.

The system displays the list of configured discovery rules.


Click png2.pngUNIFIED DISCOVERY RULE.


In the form that opens, configure the required parameters.

Parameter

Description

General

Rule name

The name of the discovery rule

Description

User-provided description of the discovery rule

Network Scan Interval (minutes)

Specifies the interval, in minutes, at which the network scan repeats

Admin State

Specifies the administrative state for the discovery rule

Up means the policy is in effect.

Discovery Protocols and Policies

(First|Second|Third|Fourth) discovery protocol

Specify the protocols to be used to communicate with the NE, in the order in which they should be used to attempt to reach the NE for discovery.

Enter all the protocols that will be used for communication, regardless of whether they will be used for discovery.

Mediation Policies

Select a policy for each protocol:

  • Click on the policy field.

  • In the form that opens, select a policy and click SELECT.

To create a mediation policy, click png2.pngNEW; see How do I create a mediation policy for MDM?.

Reachability Policies

The reachability types required for the selected discovery protocols appear in the Select Reachability Policies panel.

Click in a reachability type field.

In the form that opens, select a policy and click SELECT.

To create a reachability policy, click png2.pngNEW; see How do I create a reachability policy for MDM ?.

Associate Classic Discovery Rule

Click in the Classic Discovery Rule field.

In the form that opens, select a discovery rule and click SELECT.

To create a classic discovery rule, click png2.pngNEW; see How do I create a classic discovery rule?.

Discovery IP Ranges

Included IP Addresses

Click png2.pngADD to specify an IP address and mask bits to search. Repeat to add additional ranges.

Verify that the included IP address ranges include all the MDM and classic devices you need to discover.

Note: Nokia does not recommend the use of /24 subnets in unified discovery rules. The use of /24 subnets may cause slow discovery time.

Excluded IP Addresses

Click png2.pngADD to specify an IP address and mask bits to exclude from discovery. Repeat to add additional ranges.


Click CREATE. The discovery rule is automatically assigned a rule ID and is added to the list.


To run a discovery rule click on your discovery rule in the list and click png1.png(Table row actions), Discover.


To view results of a discovery, select the discovery rule and click Summary png3.png to view the Summary panel. In the panel at the right of the screen, click Errors png4.png to see details about any errors that occurred the most recent time the discovery rule was run.
