Understanding Cisco Industrial IoT Networking Foundation (INFND)

The Understanding Cisco Industrial IoT Networking Foundation (INFND) v1.0 course gives you an overview of the protocols, applications, and network infrastructure you need to support and manage Industrial Internet of Things (IIoT) solutions. You will learn about IIoT industry verticals and how different protocols are used within them. The course also covers configuring and verifying the protocols on Cisco® IIoT networking devices.

How you’ll benefit

This course will help you:

  • Understand what IIoT is, IIoT market verticals, and the related standards
  • Understand the protocols, applications, and network infrastructure needed to support IIoT solutions
  • Identify Cisco IIoT networking devices and how they are different from other devices
  • Configure and verify IIoT networking devices to support IIoT solutions

Who should enroll

  • Operational Technology (OT) Engineers
  • IT engineers
  • Generalists, including managers, project leads, and solutions and business architects


  • Define what IIoT is and identify IIoT architectures.
  • Identify IIoT market verticals, and their motivations and requirements.
  • Explore Cisco IIoT networking devices, how they are different from other devices, and use common administrative tools for managing them.
  • Explore industrial communications protocols for control and automation, and how they have been adapted to run on top of a TCP/IP network infrastructure.
  • Describe wireless protocols used in IIoT environments, including architectures and devices used.
  • Understand the TCP/IP protocol stack and how it is used with other protocols in IIoT environments.
  • Discuss network protocols for clock synchronization between network devices, and describe available tools for IIoT network administration.
  • Discuss wireless technologies used in a core LAN, and their relevance to IIoT implementations.
  • Explore field WAN technologies and how they are used in IIoT environments.
  • Explore legacy protocols and explain the methods available to transport non-routable protocols over modern networks.
  • Explain fundamental concepts of Quality of Service (QoS) related to IIoT network environments.
  • Discuss Multiprotocol Label Switching (MPLS) operation, components, terminology, and features, and explore its use in IIoT environments.
  • Explore Layer 2 and Layer 3 VPN technologies and describe the way they can be used on IIoT deployments.
  • Describe Dense Wave Division Multiplexing (DWDM) technology and its use in IIoT environments.
  • Explore Layer 1 and Layer 2 high availability technologies and redundancy mechanisms.
  • Describe Layer 3 high availability and the need for Layer 3 redundancy in IIoT deployments.


The knowledge and skills that students are expected to have before attending this course are:

  • CCNA® Routing and Switching (R&S) (or equivalent knowledge).
  • Either the Control Systems Fundamentals for Industrial Networking (ICINS) course, the Managing Industrial Networks for Manufacturing with Cisco Technologies (IMINS2) course, or equivalent knowledge.
