Is this a replacement for Visio? GNS3 now allows you to create interactive topology diagrams. You can create topologies consisting of both physical and virtual devices and get them to communicate with each other.

Will gns3 replace visio? How will you make the most use of this new feature in gns3?

Fantastic new feature is available in GNS3 2.2! Cisco IOS routers and switches (and others) can detect the status of interfaces - is the cable plugged in? Or not? Has the link been suspended?

GNS3 2.2 New Feature: Detect when a link is plugged/unplugged for Qemu VMs.

Qemu VMs will be informed when a link is plugged or unplugged or even when suspended. This should be really useful when testing redundancy scenarios, protocol convergence etc.

This will really help with gns3 labs in future!

Want to know to install, configure and setup GNS3 2.2? Well, these videos show you. In my first video, I show you how to download the components you require and how to install the GNS3 GUI on Windows 10. We build a basic network with GNS3. In the second video I show you how to use the GNS3 2.2 Web-UI and in this video I show you how to integrate the GNS3 VM with the GNS3 GUI. In the next video I show you how to build a network using Cisco VIRL IOS images.

Thank you Jeremy for all your hard work creating and updating GNS3!
