Switching and GNS3 One common misconception about GNS3 is that GNS3 does not support advanced switching options. 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. 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. NOTE Instructions on configuring a c3725 router to act as an “etherswitch router” (or “swouter”), with a few basic instructions are found at the bottom of this document 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. Fancycache keygen crack generator.

This is a rather simple process, but be aware that your options for configuring Cisco switching while using a c3640, c3660, c3725, and c3745 for this are quite limited. This example will use a c3725 router IOS image, but the same steps apply if using the other three platforms listed above. First, click Edit->Preferences->IOS Routers->New in the GNS3 GUI. Pick whether you’ll run this IOS image via the local server, or the GNS3 VM (if installed), and click Next >: Select New Image, and click Browse to locate the image in your filesystem (you must supply your own). Select the image file, and click Open: You’ll be asked if you’d like to decompress this image. Choose Yes, as it will load faster, instead of decompressing every time you start the image: Click Next > to continue: At the page where you’re asked to name the router, select the “ This is an Etherswitch router” option (this is important). It will automatically name the device Etherswitch router, and mark it to be placed into the Switches device category, instead of Routers.

Never attempt to replace that GT96100-FE adapter with a switch module, as it will not work. You can add a second NM-16ESW,a NM-1FE-TX single FastEthernet adapter, or an NM-4T serial port adapter to slot 2.

Click Next >: You can add WIC modules on the next page, consisting of either WIC-1T or WIC-2T serial port adapters. It’s not a bad idea to add a few serial WICs to this Etherswitch Router, but you can skip this step if you choose. Whichever you decide, click Next > to continue. This device will already have an idle-pc value specified, so you can go ahead and click Finish If the IOS image you’re using does not, then click the Idle-pc finder button in the upper-right corner, wait a little bit, and GNS3 will show you a value that it has found. Click OK for it to add that to the green bar on this page, and then click Finish.
