Implementing Aruba OS CX Switching Course

Implementing Aruba OS CX Switching, Rev 20.21 Instructor Led Training (ILT) and virtual (vILT)

Course Description

This course teaches you the advanced skills necessary to implement and operate enterprise level Aruba campus switching solutions. You will build on the skills you learned at the Associate level to configure and manage modern, open standards-based networking solutions using Aruba’s OS-CX routing and switching technologies. In this course, participants learn about ArubaOS-CX switch technologies including: securing port access with Aruba’s dynamic segmentation, redundancy technologies such as Multiple Spanning Tree Protocol (MSTP), link aggregation techniques including Link Aggregation Protocol (LACP) and switch virtualization with Aruba’s Virtual Switching Extension (VSX) and Aruba’s Virtual Switching Framework (VSF). This course is approximately 50% lecture and 50% hands-on lab exercises.
