Switching and GNS3 One common misconception about GNS3 is that GNS3 does not support advanced switching options. Linux file system basics. While this was true in the past, GNS3 now supports options such as: • Etherchannel • PVST+ • RPVST+ • MST • Port Security • DTP • And many others. Complimentary campus technologies such as HSRP are also supported. Your selection of image and platform will affect what is possible. Options include: • Cisco IOSvL2 • Etherswitch module • IOU • GNS3 built in switch • Openvswitch • Others Recommended_switching_platform Cisco VIRL IOSvL2 With a Cisco VIRL IOSvL2 image, you can configure and test a wide range of advanced switching features.

Mar 02, 2015  Today I’m going to discuss How to install and configure Cisco IOU in GNS3. 2 switch in GNS3-1.1. Cisco IOS on UNIX (IOU). GNS3 IOU VM, and login. Ios cisco 3750 -sw cisco switch ios images for gns 3 free cisco. Recommended Lab equipment for Cisco CCNA. Cisco IOS, CCNA, CCNP, Networking Academy. This video shows how to use GNS 3 with Cisco IOU L2 / L3. GNS 3 L2 IOU VM Cisco Switch Easy Step by Step.

Go here for a full list: This is the official Cisco way of emulating a switch. Basic_switching Etherswitch module While an Etherswitch module does not support advanced layer 2 features, it does allow you to configure basic VLANs, Spanning Tree and other options. IOU is a less resource intensive alternative to IOSvL2, but the images are not publicly available. You will need to get them from someone who works at Cisco.

In addition, as this is a Cisco internal tool, IOU mages may be buggy and no support is available. Use this if all you need is a basic switch to connect devices in a GNS3 topology. You cannot configure this switch through a CLI, but you can set the number of ports supported on the switch and other basic settings. Note It’s not running a switch OS, everything is emulated from scratch. This mean some protocol could be buggy. Use it only for basic operations By leveraging GNS3 support for Docker, you can now add Open vSwitch to your GNS3 topologies.

In order to do that, use this template: You can also use switches from other vendors such as Cumulus, Extreme Networks and many more.
