Aruba OS-CX Switching Fundamentals [HQ7A9S]

OVERVIEW

This course teaches you the fundamental skills necessary to configure and manage modern, open standards-based networking solutions using Aruba's OS-CX routing and switching technologies. This course consists of approximately 60% lecture and 40% hands-on lab exercises to help you learn how to implement and validate small to medium enterprise network solutions. This 5-day course prepares network professionals for the Aruba Certified Switching Associate exam.

In this course, participants learn about ArubaOS-CX switch technologies including: Virtual Local Area Networks (VLANs), secure access using features like dynamic segmentation, redundancy technologies such as Multiple Spanning Tree Protocol (MSTP), link aggregation techniques including Link Aggregation Control Protocol (LACP), and switch virtualization with Aruba’s Virtual Switching Framework (VSF). You also learn about IP Routing including static and dynamic IP routing with Open Shortest Path First (OSPF).
