About this course
Course Overview
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 an overview of NSO as a network automation solution, as well as introductions to NETCONF, YANG, and XPath. You will learn about managing devices and creating device templates, service management and service package creation, network element drivers, interfacing with other systems using APIs, configuring and troubleshooting system settings, managing alarms and reporting, configuring NSO for scalability and performance, and capabilities that can be added to Cisco NSO.
This course is worth 40 Contnuing Education (CE) Credits.
Target Audience
System installers, system integrators, system administrators, network administrators, and solutions designers.
Course Objectives
