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.

Note: At least one MDM mediation policy and at least one MDM reachability policy are mandatory for unified discovery rule creation, regardless of whether the rule will be used to discover model-driven devices.

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 UNIFIED 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 NEW; 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 NEW; 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 NEW; see How do I create a classic discovery rule?.
Discovery IP Ranges
Included IP Addresses	Click ADD 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.
Excluded IP Addresses	Click ADD 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 (Table row actions), Discover.

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