HP released the first public available HP Network Simulator software today. It was tested internally by the technical folks and is now available to everyone. You will find it here:
The HP Network Simulator will create a virtual environment with Comware7 based network devices. It is very helpful for getting started with HP network equipment or for testing. It is also a good starting point when learning for the available certification path as the HP Network Simulator does not need any networking equipment. It will run on your PC or laptop.
The HP Network Simulator is treated as an Open Source tool, which means, everyone can help to make it better.
