ServiceNow Integration with IP Fabric

IP Fabric

IP Fabric is a vendor-neutral network assurance platform that automates the holistic discovery, verification, visualization, and documentation of large-scale enterprise networks, reducing the associated costs and required resources whilst improving security and efficiency.

It supports your engineering and operations teams, underpinning migration and transformation projects. IP Fabric will revolutionize how you approach network visibility and assurance, security assurance, automation, multi-cloud networking, and trouble resolution.

Integrations or scripts should not be installed directly on the IP Fabric VM unless directly communicated from the IP Fabric Support or Solution Architect teams. Any action on the Command-Line Interface (CLI) using the root, osadmin, or autoboss account may cause irreversible, detrimental changes to the product and can render the system unusable.

Overview

This project syncs devices from IP Fabric's Inventory to ServiceNow's CMDB Network Gear Table.

CLI Utility Installation

pip install ipfabric-snow

ServiceNow Configuration

Please see the ServiceNow Configuration section for details on how to configure ServiceNow for use with this integration.

Environment Setup

Copy sample.env to .env and fill in the necessary details. During the setup, you'll be prompted to enter the necessary environment variables including URLs and authentication details for both ServiceNow and IP Fabric.

Quick Start

To sync devices from IP Fabric to ServiceNow, run:

ipfabric-snow sync devices 

If the environment is not properly set up, you'll be prompted to set it up. Follow the prompts to provide the necessary details.
