GNS3 Windows Install
GNS3 Graphical User Interface
This document explains various options in the GNS3 Graphical User Interface (GUI) which help you create and manage GNS3 projects.
This guide applies to both the Local Server and GNS3 VM installations. Both installation options use the same user interface for the management of projects.
The following figure shows a screenshot of the version 1.5 GNS GUI:
The GNS3 toolbar found at the top of the GNS3 GUI, contains groups of icons that allow you to easily perform common tasks.
The toolbar groups icons into specific functions or features. This gives you a simple way of getting things done.
The first group allows you to create, open and save projects:
Click the New Blank Project button to create a new project in GNS3. You will be asked for your new project name and folder to save the new project.
To create a new GNS3 project, click the New Blank Project button on the GNS3 Toolbar:
If you have devices running, GNS3 will warn you to shut them down before opening an existing object:
If you have an unsaved project currently opened, GNS3 will remind you to save It so you don’t lose your changes:
GNS3 will prompt you for the Name and Location of your new project.The default name is untitled and default location C:\Users\<username>\GNS3 in Windows:
Give your project a name, change the location if desired and click OK
Click the Open Project button to open an existing GNS3 project. You will be asked for your new project name and folder to save the new project.
An Open project window will display. Navigate to the GNS3 projects folder. By default this is C:\Users\<username>\GNS3 in Windows:

The second GNS3 Toolbar Group allows you to create project snapshots, show or hide interface labels and connect to device consoles:
Click the Snapshot button to create a snapshot of your devices, links and IOS configurations. Snapshots in GNS3 are similar to snapshots in other systems such as VMware which allow you to create a saved version of your project at a specific point in time. You can then revert back to this later.
If you want your router configurations saved, make sure you save them via the router CLI before you save the GNS3 project.
