# get the host id and host name to calculate the hostkey Print "Cisco IOU License Generator - Kal 2011, python port of 2006 C version" Copy the following script and paste it to the file: #! /usr/bin/python Create an iou keygen file in the EVE directory for iou images: vim /opt/unetlab/addons/iol/bin/ioukeygen.pyĢ. How to generate IOU licenseįollow the next steps to generate IOU license:ġ. We have seen in the previous post in this tutorial that the IOU nodes didn’t start and this is because you need to license the IOU/IOL images to work inside EVE-NG. Via EVE-NG, you don’t need the Cisco simulator to use IOU/IOL in your labs. However, they are widely used in EVE-NG due to their efficient resource consumption and rich features. The IOU simulator was released by Cisco for their tests, not for the public usage.
BackgroundĬisco IOU images are a good choice to emulate IOS router/switch inside Unix/Linux machine.Ĭisco IOU/IOL emulation supports the features and functions that the real IOS devices support while consuming resources much less than those used with other emulation solutions such as dynamips. However, this post is related to EVE-NG itself ,whether in the cloud or on your own workstation.
This tutorial so far demonstrated how to get EVE-NG in Google cloud. You should generate IOU License to start it inside EVE-NG. In a a previous video, I showed you how to download and install VMware Workstation Player and how to add EVE-NG to VMware, how to create a topology.Cisco IOU refers to Cisco IOS on Unix (IOU) or Cisco IOS on Linux (IOL). Use this EVE-NG tutorial to add Cisco images to EVE-NG and get an EVE-NG lab set up. This video is part of a series of videos that give you a full EVE-NG installation guide. This EVE-NG tutorial shows you step by step how to download Cisco IOS images, how to upload them to the EVE-NG server and then how to use them in EVE-NG topologies. How do you add and use Cisco images in EVE-NG topologies? This video shows you how to download Cisco IOS images from Cisco VIRL and then use them in your EVE-NG networks.
