Description

Network Programmability for the Enterprise (NPEN) v1.0 is a four-day instructor led course. This course teaches how to automate common Cisco enterprise platforms such as IOS-XE and IOS-XR routers as well as ASA firewalls. This course also includes coverage of the automation capabilities of the APIC Enterprise Module or �APIC-EM�. Applying CCIE-style learning methods, the course places emphasis on learning via hands-on labs and hands-on demonstrations. The terms �proof-by-Python� and �proof-by-JSON or XML� will be used frequently throughout the course.

Objectives

Upon completing this course, the learner will be able to meet these overall objectives:

(Network Programmability for the Data Center (NPEN v1.0)

  • Use Linux tools that empower network programmers
  • Write and troubleshoot Python scripts in the specialized area of Network Programmability
  • Understand and interact with Data Models on Cisco routers running IOS-XE and IOS-XR
  • Understand and interact with REST, NETCONF and RESTCONF API�s on IOS-XE, IOS-XR and the ASA
  • Understand and interact with XML and JSON on IOS-XE, IOS-XR and the ASA
  • Understand and interact with the APIC-EM and its REST/SWAGGER interface
  • Learn how to use DevOps tools such as GitHub, VIRL and services offered by Cisco DevNet
  • Learn how to use Ansible to configure Cisco routers and firewalls

Prerequisites

It is recommended that each student has the following knowledge and skills before attending this course:

  • CCNP or Equivalent Experience
  • Complete the Programming for Network Engineers (PRNE) ELT or equivalent Python programming experience such as the Skyline-ATS IPWSP-NE course.

Who Should Attend

This course is designed for network engineers who want to learn how to deploy network programmability and automation using the following Cisco platforms: the Cisco routers running IOS-XE or IOS-XR, ASA firewalls, or the APIC Enterprise Module (APIC-EM).
