NE resync auditing overview

Functional description

The NE resync audit function detects and reports differences between the NFM-P database version of the NE configuration and the version stored on the NE. The NE resync audit manager displays a list of misaligned parameters and values as represented in the NE and NFM-P databases, and provides quick navigation to the affected object. A resync audit polls the NE in the same manner as a standard full resynchronization, but instead of updating the objects in the NFM-P database, the NFM-P compares the NE configuration retrieved by the resync with the NE configuration in the NFM-P. See To perform an NE resync audit for information about performing an NE resync audit.

Differences identified during the audit are displayed in the Show Difference manager. In this manager, you can navigate to the associated NE object that contains the difference and perform a resync on that object to resolve the difference. You can access the results of one audit per NE in the NE audit result list.

You can specify whether to include or ignore read-only parameters in a resync audit. Some read-only parameters are set by the NE after a configuration change. Other read-only parameters, such as temperature measurements and time stamps, change frequently on the NE and will often differ from the values in the NFM-P database. Disabling the inclusion of read-only parameters can help prevent cluttered audit results.

The difference entries that an NE resync audit returns are categorized as follows:

• Property Change—the value of a specific parameter is different in the NFM-P and NE databases

• Missing—the object and contained parameters exist in the NFM-P, but not on the NE

• Added—the object and contained parameters exist on the NE, but not in the NFM-P

Additional information

Consider the following information about NE resync audits:

• The NFM-P limits the audit result to 1 000 differences.

• NE resync audits only compare parameters that are synchronized with the NFM-P database. Parameters that are stored in the NE database only and are not managed by the NFM-P are not included in the audit report.

• NE resync audit results do not include statistics.

• NE resync audits cannot be used to deploy changes to an NE.

• You cannot perform a full resync from the NE audit manager or Show Differences form.

• Dynamic read-only objects and dynamic parameters are excluded from NE resync audits. For example, the following objects are excluded: LDP session, RSVP session, MPLS In Segment, Out Segment, Cross Connect, MPLS Actual Hop and Actual Path, ISIS SPF Log.
