Choose Administration→Discovery Manager from the NFM-P main menu. The Discovery Manager form opens.

Click Create to create a new discovery rule. The Create Discovery Rule step form opens.

Note: When you are finished each step, click Next to advance to the next step. You can click Finish at any time.

Depending on the purpose of the discovery rule, not every step in this procedure needs to be completed.

Configure the required parameters in the Specify General Attributes step.

Note: When you close the Discovery Manager form, the NFM-P scans the network using the discovery rule, if the Administrative State parameter of the discovery rule is set to Up.

The Group Name parameter specifies the equipment group that discovered NEs are added to. If the selected equipment group reaches the maximum element limit, any additional discovered NEs are automatically added to the Discovered NEs group.

The Discovered NEs Group Name cannot be chosen when configuring a Discovery Rule for an EM system.

To add rule elements in the Add Rule Elements step, click Create, configure the required IP parameters, and click OK. The rule element is added to the list.

To add auto discovery rule elements in the Add Auto Discovery Rule Elements ACL step, click Create, configure the required parameters, and click OK. The rule element is added to the list.

In the Configure Mediation Security step, click Select in each of the following panels, as required, to specify the mediation security policies for:

• Read Access Mediation Policy

• Write Access Mediation Policy

• Trap Access Mediation Policy

• Security Access Mediation Policy

Note: If you do not specify a policy, the default policy is applied.

A Wavence MSS-1c discovery rule requires the default SNMPv2 read and write access policies.

In the Configure Management Ping Policy step, click Select in each of the following panels, as required, to specify the ping policies for:

• Out Of Band Management Interface Ping

• In Band Management Interface Ping

• Standby CPM Ping

Note: If you do not specify a policy, the default policy is applied.

Management ping policies are created using the Mediation configuration form. These are the policies applied during discovery rule creation. You must apply a ping policy even to interfaces that do not exist. When there is no interface, you must choose a ping policy that has its Schedule Enabled parameter set to disabled.

For example, if there is no standby CPM or out-of-band management IP address, specify a ping policy that has the Schedule Enabled parameter set to disabled for the nonexistent management and standby CPM interfaces. In this example, a ping policy with the Schedule Enabled parameter enabled is required for the in-band interface that does exist. See To configure device mediation for information about creating ping policies.

In the Configure MIB Statistics Policy step, select a MIB statistics policy, if required.

In the Add Discovered Routers to Span(s) step, click Add to specify a span of control for the new NE contained in the discovery rule. If you do not specify a span, the default span is applied.

Note: New devices added to a span from a discovery rule are added explicitly to the span. When a discovered NE group is part of a user-defined span, new devices that are discovered using the discovery rule are automatically added to the span.

In the Configure Backup Policy step, select a backup policy, if required. If you do not specify a backup policy, the default policy is applied.

If the NFM-P manages wireless NEs in your network, perform the Add NE Self Config Policies step.

To configure an EMS in the Add EM Systems step:

1. Click Create. The EM System (Create) form opens.

2. Configure the required parameters in the General tab.

3. Click on the Element Managers tab.

4. Click Create. The Element Manager (Create) form opens.

   Note:

   After discovering an EM system, the system should be opened and its administrative state set to Up in order to enable the connection to the NFM-P. A maximum of four EM Systems may have their administrative state set to Up at any time within the NFM-P.

   A manual resynchronization must be performed in order for alarms from an EM system to be displayed in the NFM-P. This does not apply to the NEtO EM system for Wavence devices; alarms are aggregated automatically provided the Trap Access Mediation policy in the Discovery step form is configured.

   The NFM-P is able to manage 10 000 alarms per EM system. When this limit is reached, a critical alarm is raised and new incoming alarms are deleted. When the alarm counter for the EM System drops to 9000, the critical alarm is cleared and the NFM-P performs an alarm resynchronization on the EM system.

5. Configure the required parameters for host, communication, and identification.

6. Save your changes and return to the Create Discovery Rule form.

To specify a post-discovery action in the Add Post Discovery Action step, perform one of the following:

1. Click Select and use the list form that opens to associate an existing post-discovery action with the discovery rule.

2. Create a post-discovery action to associate with the discovery rule. Perform the following steps.

   1. Click Select. The Select Post Discovery Action form opens.

   2. Click Create. The Post Discovery Action (Create) form opens.

   3. Configure the required parameters:

   4. Click Select beside the Control Script Name parameter and use the list form that opens to choose a control script.

   5. Click Select beside the Control Script Instance Name parameter and use the list form that opens to choose a control script instance.

   6. Save your changes and close the form.

   7. Select the new post-discovery action and click OK. The new post-discovery action is associated with the discovery rule.

Click Finish to close the Create Discovery Rule form.

Apply your changes in the Discovery Manager form. If the Administrative State of the newly created discovery rule is set to Up, the NFM-P scans the network using the discovery rule.

See Workflow for device discovery for other optional steps.
