Course Overview

This advanced four day instructor-led class provides an overview of methodologies and tools for troubleshooting Aruba based networks in an AOS 6.X environment. Labs are designed to inject problems into the student networks in a controlled fashion to demonstrate how various symptoms appear. Therefore, when problems are seen in a production environment, they will be more quickly identified and remedied

Upcoming Classes

Who should attend?

This course is designed for individuals responsible for the provisioning and configuration maintenance of an Aruba based network. This course is not a hardware troubleshooting oriented class. Rather it focuses on the commands and screens necessary to diagnose network and wireless related issues.


Knowledge level at the ACMP level. Students must be comfortable with provisioning profiles for various aspects of the Aruba Controller. The labs are written as objectives and are not documented in a step by step manner. Therefore, the student must know how to provision a controller without reliance upon detailed lab instructions.
