1 Overview

This chapter provides an overview of the Oracle Communications Network Integrity Cisco Router and Switch UIM (Unified Inventory Management) Integration Cartridge.

Modeling a Logical and Physical Device Hierarchy

The Network Integrity Cisco Router and Switch UIM Integration Cartridge is an extension of the Network Integrity Cisco Router and Switch SNMP Cartridge, and provides Cisco-specific functionality including:

This cartridge produces both logical and physical device hierarchies that represent a discovered device. The logical hierarchy includes a logical device, child interfaces, subinterfaces (collectively called interfaces), and device interface configurations. The physical hierarchy includes physical device, equipment, equipment holders, and physical ports. In addition, this cartridge creates associations between the physical and logical hierarchies. The first association is at the device level, between the physical device and the logical device, and the second association is at the interface level between physical ports and Interfaces.

Figure 1-1 shows a sample discovered physical device hierarchy. This hierarchy is displayed in the Network Integrity user interface, in the Scan Result Detail page.

The scan requires that devices support the following MIBs to acquire complete and meaningful results and to properly model both the physical and logical sides.

The discovery of a specific device fails if the target device does not support MIB II or the device is not of vendor type Cisco. This does not necessarily mean the scan in its entirety fails. For example, if you have a scan with a broad scope (for example, multiple IP addresses), only the devices that do not meet the required criteria fail to be rendered; other devices within the scan may succeed. You can inspect the failed device to determine the cause of the failure.

In addition to discovery, this cartridge provides discrepancy detection, discrepancy resolution, and import functionality for integration with UIM.

Discrepancy resolution allows the discovered logical and physical device tree to be created and updated in UIM.

Import allows a logical and physical 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 and physical device trees between what is discovered and what is imported from UIM. Filtering is required to set the boundaries of the comparator.
