How to Setup Cisco IOU L2 Appliance on GNS3

GNS3 is a continuously developed network emulator program. And those who prepare for the Cisco exams are more likely to use the GNS3 program. The biggest advantage of using this software is that it is free. Furthermore, many detailed network designs can be designed and run on it.

Many people had problems with using Cisco Switch on GNS3. With the Appliance structure, it is now easier to install and use the network device.

In order to use Cisco IOU images in the GNS3 program, GNS3 VM Server must be installed. Otherwise, you will not be able to install the IOU.

In addition, you can check out our articles on How to Import GNS3 VM and How to Make the GNS3 VM Network Connection.

How to Add IOU to GNS3

In order to use Layer 2 Switch, you need to download the necessary IOS image and import it with this application. You can find the IOU L2 Appliance installation file at the end of the article.

To import the IOU image, follow the steps below.

   Step 1

After you download the Cisco IOU L2.gns3a file to your computer, double-click it.

Click Edit / Preferences to add a Layer 3 Switch on GNS3..

What is IOU in GNS3?

IOU is IOS on Unix (Solaris, if you want to be specific). It's a version of IOS compiled to run on workstations. It's faster and lighter than emulation. Cisco transitioned to IOL images, which are x86-64 compatible versions of IOS that natively run in Linux.

What is Cisco IOU l2?

Cisco IOU. Cisco IOS on UNIX (IOU) is a fully working version of IOS that runs as a user mode UNIX (Solaris) process. IOU is built as a native Solaris image and run just like any other program. IOU supports all platform independent protocols and features.

Can GNS3 emulate switches?

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. - And many others. Complimentary campus technologies such as HSRP are also supported.
