What is a unified discovery rule?

Unified discovery rules

A unified discovery rule can be used to discover model-driven and classic devices in specified IP address ranges, so that you can manage them in NSP.

The discovery rule provides the protocols and policies required to discover model-driven devices.

To use the unified discovery rule to discover classic devices, you must associate a 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.

When the unified discovery rule scans the network, it performs discovery using both MDM and classic:

• For host addresses (/32), NSP first tries to discover the devices in the IP address ranges using MDM. If MDM discovery fails, the IP addresses are pushed to NFM-P for classic discovery.

• For subnet discovery, the subnet IP address will be sent to both NFM-P and NSP MDM for NE discovery at the same time.

Note: NSP does not support IP address overlap in discovery rules: an IP address cannot be included in more than one discovery rule, and a host IP address cannot be included in a discovery rule if the rule includes a subnet the host IP address is in.

Note: A unified discovery rule must include at least one MDM mediation policy and at least one MDM reachability policy, regardless of whether any model driven devices are in the specified IP ranges.

Select a discovery rule in the Device Discovery, Unified Discovery Rules view to see rule components, discovered NEs and any errors that occurred during discovery.

Note: Nokia AIM devices serve as controllers for MAG-c-a2 appliances. You can discover an AIM using a unified discovery rule.
