Aruba OS-CX Switching Fundamentals, Rev. 20.21

5 Days

30 CPD hours

Ideal candidates are IT Professionals who deploy small-to-medium scale enterprise network solutions based on Aruba products and technologies.

After you successfully complete this course, expect to be able to:
Explain Networking Fundamentals
Describe and review the Aruba Switching portfolio with customers
Install and configure devices running the ArubaOS-CX Network Operating System
Describe and configure VLANs
Explain, describe and configure Spanning Tree Protocol
Understand when to use VRRP and how to configure it
Explain and configure Link Aggregation

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 candidates for the Aruba Certified Switching Associate exam.In this course, participants learn about ArubaOS-CX switch technologies including multi-layer switches. You will also learn about broadcast domains and Virtual Local Area Networks (VLANs); secure management protocols such as AAA, SSH, HTTPS, and Dynamic Segmentation using Aruba's Role-Based Access Control (RBAC); availability 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). Static and dynamic IP routing protocols such as Open Shortest Path First (OSPF) are also covered.
