NSO201: NSO Essentials for Programmers and Network Architects (NSO201)

The Cisco NSO Essentials for Programmers and Network Architects (NSO201) course introduces you to Cisco® Network Services Orchestrator (NSO). You will learn to install Cisco NSO and use it to manage devices and create services based on YANG templates with XPath. This course provides a brief overview of NSO as a network automation solution, as well as an introduction to NETCONF, YANG, and XPath. You will learn about service packages, network element drivers, and Application Programming Interfaces (APIs). The course also covers service creation, device and configuration management, NSO maintenance, NSO options and integrations, and basic NSO troubleshooting.

Course Objectives

After completing this course the student should be able to:

  • Explain transactional service activation and how it relates to business requirements
  • Explain the benefits and uses of Cisco NSO
  • Explain how Cisco NSO communicates with network devices
  • Understand the NETCONF protocol and be able to read and write simple YANG models
  • Install NSO and describe how NSO uses NETCONF and the Device Manager component
  • Understand the difference between devices that are fully NETCONF capable and those that are less or not NETCONF capable
  • Explain the YANG service model structure
  • Describe how YANG is used with NSO, create and deploy a service, and explain NSO FASTMAP
  • Design and manage services with YANG models
  • Perform NSO configuration and basic troubleshooting, and describe the following NSO features: integration options, alarms and reporting, scalability and performance options, and available function packs
  • Use logs to troubleshoot the Cisco NSO deployment and check NSO communication with network devices
  • Explain the mapping logic of service parameters to device models and consequently to device configurations
  • Describe the use of different integration options and APIs
  • Explain the use of Reactive FASTMAP for manipulating and implementing advanced Network Functions Virtualization (NFV) components
  • Describe the use of feature components and function packs
  • Define and explain the European Telecommunications Standards Institute (ETSI) Open Source NFV Management and Orchestration (MANO) principles and solution
  • Work with the alarm console, and understand the NSO alarm structure and how it conforms to modern network operations procedures
