Course Overview

The ArubaOS-CX course provides students with information on ArubaOS-CX routing and switching, Network Analytic Engine (NAE), and the virtualization of the distribution layer and core layer of a campus network. Students will use CLI, WebUI and REST API to understand how to incorporate ArubaOS-CX technologies into their network.

This course teaches students how to use python scripting to help automate their daily network routine and how to use the built-in NAE swagger to monitor and help troubleshoot their campus network. Students will learn how to leverage the high availability (resiliency, performance, scalability, and flexibility) of ArubaOS-CX 8400/8320 switches as well as the design and placement of 8400/8320 switches.

Course Duration

4 days (Classroom or Virtual)

Target Audience

Network Professionals that are looking to further advance their expertise and manage networks based on HPE ArubaOS-CX technologies.

Course Prerequisites
