Guidance Note 3: Inspection & Testing (Electrical Regulations)

Product Information

Classroom environments can also benefit from a preconfigured lab environment that students use to learn networking concepts and technologies. First, open your terminal: For the GNS3 installation, you have to open your terminal. Either you can search Terminal in installed programs, or you can press the Alt+Ctrl+T shortcut key.

You are now ready to integrate the new VM with GNS3. Add a virtual machine to GNS3 (Local Server) ​ After importing this virtual machine into GNS3, adding it to a topology, and powering up, GNS3 happened to select Host-only VMnet 2, during the creation of this article: GNS3 will randomly select an available Host-only VMnet to bridge the VMware virtual machine into the GNS3 topology. VMnet 0 (bridged), VMnet 1 (host-only), and VMnet 8 (NAT) are available in VMware by default, but will not be used by GNS3 for this purpose! In GNS3, by default, the hostname of a Router is either R(1) or Router(1). When you take more than one router, the number (1) is increased by the number of routers you take. The below command can be used to change the hostname of a Router using CLI :If GNS3 starts and presents a Setup wizard, it verifies you have successfully installed GNS3. When GNS3 starts the first time, it presents the Setup wizard. This wizard allows us to configure and install the GNS3 server. We will configure the GNS3 server in the next part of this tutorial. You may find a lot of tutorials on the Internet explaining how to extract ASA 8 images from physical hardware devices and use them with GNS3. This method was the only way to get an ASA image in the past, but the results are random; and getting worse with modern computers and operating systems. For example Windows 10 has multiple issues running ASA 8. When you first created the TinyCore-Local-VMware virtual machine, it was set to use a NAT (VMnet 8) by default:

Performing that operation varies between antivirus suites, so you’ll need to refer to their relevant documentation to learn how to do this. If you will install the GNS3 server on the local system without a virtual machine, select the following components and tools.

VMware Workstation Players (and VMware Workstation Pro users) can use a script included with GNS3 (named gns3vmnet) to automatically create and configure the additional VMnets necessary. Create dynamic network maps for troubleshooting and proof of concept (POC) testing: - Test your networks before you build them to reduce the time it takes to get a production network up and running The local GNS3 server runs locally on the same PC where you installed the GNS3 all-in-one software. If for example you are using a Windows PC, both the GNS3 GUI and the local GNS3 server are running as processes in Windows. Additional processes such as Dynamips will also be running on your PC: Drag and drop the selected node (device) to the GNS3 Workspace. An instance of the node becomes available in the Workspace. In this example, the TinyCore PC is now available:
