AOS-CX Switching Fundamentals Description
The AOS-CX Switching Fundamentals course teaches you the essential skills necessary to configure and manage modern, open standards-based networking solutions using AOS-CX routing and switch technologies.
This training 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 AOS-CX Switching Fundamentals program prepares network professionals for the Aruba Certified Switching Associate exam.
In this AOS-CX Switching Fundamentals course, participants learn about AOS-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 routing with Open Shortest Path First (OSPF).
This course is also available in Dutch: AOS-CX Switching Fundamentals NL (0001208242)
