The above image is listing the name of the PC, indicating that you’d like to run this node via the local server. Select whichever you wish, since VPCS can run in either. If you already have the GNS-VM imported and configured, you’ll be prompted to select whether you wish to run the VPCS node via the local server or the GNS3-VM. Next, click on End devices in the Devices Toolbar, and drag and drop an instance of VPCS (a simple PC simulator) into the Workspace, which will be called PC-1: An instance of the device called Ethernetswitch-1 will now be available in the topology. Drag and drop the built-in ethernet switch to the GNS3 Workspace as shown below. To create your first GNS3 topology, first click on Switches in the Devices Toolbar. In this example, the VPCS device is one of the available types: The toolbar will expand to show available devices of that type. To create a new GNS3 topology, click the Browse End Devices button on the Devices Toolbar: Lastly, the GNS3 Console is at the bottom of the GNS3 GUI:Įrrors GNS3 encounters while executing tasks will be written here, and GNS3 mods may ask you to run debug commands here, to better isolate an issue you may be encountering. The local server’s resource usage includes more than just what GNS3 itself is using (if you are heavily multitasking while running GNS3, you’ll see that reflected in the resource summary), while the resource usage for the GNS3-VM is only showing what it is currently using. In this instance, the both the local server (the name of the PC) and the GNS3-VM are currently up and running. The Server Summary pane shows the Local Server status, as well as that of the GNS3-VM (if in use): The Topology Summary pane is located towards the upper-right side of the GNS3 GUI, and will list the nodes that are in the current topology:Īs you’ll see shortly, this pane not only lists the current topology devices, but also their state (on/off), as well as list the interface connections between the various nodes. You will find both simulated devices as well as emulated devices in the various device groupings. The devices toolbar is grouped into different types by default: Tool You do this by dragging devices from the Toolbar to the GNS3 workspace (explained below). The devices toolbar allows you to add devices to your network topology. This gives you a simple way of getting things done. The toolbar groups icons into specific functions or features. The GNS3 toolbar is found at the top of the GNS3 GUI and contains groups of icons that allow you to easily perform common tasks: The GNS3 workspace is the area of GNS3 where you create topologies by adding devices and links: GNS3 Toolbar The following figure shows a screenshot of the GNS graphical user interface which we will quickly discuss so you know some of the terminology used: GNS3 Workspace Name the project as desired and then click OK: Screen Layout When you first start GNS3 2.2.0, create a new project by clicking File->New_blank_project Get to know your GNS3 Graphical User Interface (GUI) On first start up This document assumes that you already have GNS3 installed.
