How to Run ArubaOS-CX in GNS3 | Full Setup & Common Fixes
In this video, I walk through how to get an ArubaOS-CX switch running in GNS3 from scratch. You’ll see the full process of downloading GNS3, importing the Aruba CX image, creating the QEMU template, and troubleshooting common issues that stop the switch from booting.
This includes:
Importing the ArubaOS-CX image into GNS3
Creating and configuring the QEMU VM template
Understanding RAM and system requirements
Fixing common startup and compatibility errors
Verifying the switch boots correctly in a lab environment
This guide is ideal for network engineers, students, and homelab users who want to lab Aruba CX without physical hardware and avoid the frustration of failed imports or misconfigured templates.
By the end of this video, you’ll have an Aruba CX switch successfully running in GNS3 and ready for future labs like VLANs, routing, and enterprise network simulations.
