The IMS Discovery Cartridge supports the modeling of devices in IMS Network and provides the following functionalities:

• Read and collect data from files provided using FTP.

• Physical discovery and modeling of devices.

• Discrepancy detection and resolution on modeled data.

This cartridge produces both logical and physical device hierarchies that represent a discovered device. The logical hierarchy includes a logical device, child interfaces, sub-interfaces (collectively called interfaces), and device interface configurations. The physical hierarchy includes physical devices, equipment, equipment holders, and physical ports. In addition, the 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.

The cartridge discovers the following network entities:

• NE

• Frame

• Shelf

• Module

• Port

• Interface

This cartridge is designed to be used on a standalone basis displaying the model hierarchy in Network Integrity. The cartridge provides no integration with other products but may be extended. This cartridge is designed to discover IMS domain devices only and attempts to discover other devices result in a scan failure.

In addition to a discovery action, this cartridge provides discrepancy detection and discrepancy resolution for integration with Unified Inventory Management.

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.

For more information about discrepancy detection actions and processors, see Network Integrity Developer's Guide.

The discrepancy resolution action enables the discovered logical and physical device trees to be created and updated in UIM.

For FTP, modeling of the device fails if it does not follow the FTP file structure properly. For more information about IMS Network FTP Input file structure, see "About IMS Network FTP Input File Structure".

This section provides information on dependencies that the IMS Discovery Cartridge has on other entities.
