GNS3 Supported Cisco Router IOS Images Download. GNS3 is more specific and professional than Cisco Packet Tracer. There is no need to add any Cisco devices to the Packet Tracer, but it is absolutely necessary to download and add the Cisco IOS for GNS3. You need to use GNS3 to use the actual Router and Switch IOS images.
GNS3 support many switching options - they range from unmanaged switches, to Cisco IOS switches, to Datacenter Nexus switches, to Etherswitch modules and then emerging technologies such as OpenFlow and SDN.
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.

IOSvL2:
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.
Etherswitch:
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:
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.
NON CISCO:
Unmanaged switching: GNS3 built in switch
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
Open vSwitch:
By leveraging GNS3 support for Docker, you can now add Open vSwitch to your GNS3 topologies. In order to do that, use this template:
