Mediation and event notification policies

Mediation policies

To discover and manage devices in your network, you must create a mediation security policy to setup the security and communication infrastructure between the NFM-P and each device within the specified discovery rule IP range.

You can also optionally configure other mediation policies to specify other network mediation tasks such as specifying the polling interval for MIB configuration changes, how the NFM-P processes specific events, and how the NFM-P pings devices in the network to ensure they are reachable.

Caution: When configuring a mediation policy, you need use a community string that uses rwa in order for the trap destination is set on the NE. This ensures fault conditions and alarms are reported.

The following table describes the device mediation policies you can configure using the NFM-P.

Table 9-1: NFM-P device mediation policies

Policy type	Purpose	See
Mediation security	Defines the network security model and communication protocols used to discover and manage NEs for all NFM-P user types except LI users. The policy specifies the SNMP, CLI, and file transfer settings, and the credentials for security functions. A discovery rule requires a mediation security policy for: read access write access SNMP trap access	To configure device mediation
MIB entry	Defines the interval at which the NFM-P polls NEs MIBs for configuration changes.
Management ping	Defines the management IP address of the device that the NFM-P pings periodically to verify reachability. You can specify which of the following interfaces the NFM-P pings: Out of Band Management Interface Ping In Band Management Interface Pin Standby CPM Ping
Event notification	Defines how the NFM-P processes specific SNMP events from specific NE types and releases. See Event notification polices in this section for more information.
LI mediation security	Defines the network security model used for LI mirror service creation; LI users do not use a standard mediation security policy. The policy specifies the NE LI user credentials, the authentication and privacy protocol types, and the required passwords. The NFM-P GUI displays an LI mediation security policy only for an LI user. See Chapter 94, Lawful Intercept for information about configuring LI.	To configure an LI security mediation policy

Event notification polices

CAUTION

Service Disruption

The NFM-P uses SNMP notifications to verify network management functions. Before you configure an event notification policy, consult Nokia support to ensure that you do not disable the processing of traps that the NFM-P requires.

To reduce the NFM-P processing load associated with SNMP events, you can configure a policy that specifies which SNMP traps the NFM-P processes. An event notification policy acts as a filter that enables or disables the processing of specific SNMP traps for a specific NE type and release.

An NFM-P operator with an admin or operations scope of command role and write access permission to the policy package can create an event notification policy during mediation configuration. The NFM-P assigns a default event notification policy to an NE during initial device discovery. You can optionally specify which traps to process and which to ignore; processing is enabled for all supported traps in the default policy.

The following conditions apply to event notification policies:

After an NE upgrade, the NFM-P processes the new traps generated by the upgraded NE. An NFM-P administrator must ensure that the event notification policies that are in effect before an NE upgrade are correctly configured, and must modify them after the upgrade for new traps, as required.
An NFM-P software upgrades does not affect an existing policy.

SNMP statistics that include the number of ignored traps for an NE are available from the Statistics tab of an NE properties form.
