1 Overview

This chapter provides an overview of the Oracle Communications Network Integrity Management Information Base (MIB) II Unified Inventory Management (UIM) Integration cartridge.

Modeling a Logical Device Hierarchy

The Network Integrity MIB-II UIM Integration cartridge enables you to discover devices in your network using the SNMP protocol.

The cartridge produces a logical device hierarchy that represents the discovered device and includes a Logical Device instance and child Interfaces or SubInterface instances (collectively called interfaces).

Figure 1-1 shows a discovered logical device.

Device Support Requirements

To acquire complete and meaningful results, the scan requires that devices support the following MIBs at a minimum:

  • RFC1213-MIB

  • IF-MIB (RFC 2863)

  • IANAifType-MIB

  • IP-MIB (RFC 4293)

The MIB-II UIM Integration cartridge can discover any device that supports MIB-II.

The MIB-II UIM Integration cartridge can hierarchically model interfaces for devices that support the IF MIB, or these devices that do not support IF MIB. The cartridge creates a flat list of interfaces in the Network Integrity GUI for all devices that do not support the IF MIB. For these devices that do not support the IF MIB, some interface field values revert to MIB-II definitions rather than the IF MIB definitions.

The MIB-II UIM Integration cartridge can poll devices for IPv6 address if those devices support IP MIB.

In addition to discovery this cartridge provides Discrepancy Detection, Discrepancy Resolution and Import functionality for integration with UIM.

Discrepancy Resolution allows the discovered Logical Device tree to be created and updated in UIM.

Import allows a Logical Device tree in UIM to be imported to Network Integrity to compare objects with what is discovered.

Discrepancy Detection provides the mechanism to allow a filtered comparison of logical trees between what is discovered and what is imported from UIM. Filtering is required to set the boundaries of the comparator. For more information, see the chapters Discrepancy Detection Actions and Discrepancy Detection Processors in Network Integrity Developer's Guide.
