This tutorial explains how install and import Cisco IOS in GNS3 step by step with practical examples. In order to use any Cisco device such as router and switch in GNS3, we must have to install that device’s IOS first. Learn how to install, configure and use Cisco IOS in GNS3 in detail.

Since Cisco IOSs are protected by copyright laws, GNS3 does not include any Cisco IOS in default installation. It only provides a platform to use Cisco IOS but it does not provide any Cisco IOS itself. It means, in order to use any Cisco device in GNS3, we must have to install that device’s IOS first. This tutorial explains how to install necessary Cisco device’s IOS in GNS3.

Downloading Cisco IOS

In order to install Cisco device in GNS3, we must have to obtain its IOS file. There are several sources from where we can obtain this file. We can get it from real Cisco device, or can download it from Cisco’s official site (it requires a valid Cisco account and license agreement) or can download it from educational sites. If none of these work for you, simply search following term in Google.

You may check this site http://tfr.org/cisco/. It contains the largest collection of Cisco IOSs. I found this site through Google search. It may be may not be working at this moment.

It explains how to install and configure GNS3 step by step with practical example.

Cisco ios image

Download the IOS file

Open GNS3 and click Edit file menu and from sub-menu click Preferences

Navigate to Dynamips -> IOS routers option in left pane and click New button in right pane

Ios

Select New Image option and click Browse button. Now select the downloaded IOS image file

By default IOS files are compressed. GNS3 supports both compressed and decompressed format.

Keep the compressed format

Verify that correct file is selected and click Next button

If selected IOS belongs to an outdated device, wizard may display a warning message.

In real life, using an outdated device is not recommended. Since GNS3 uses a real Cisco IOS, it also follows the same recommendation and warns us about the outdated IOS. If we are going to use this device only for CCNA exam preparation or to get some hands on experience on Cisco IOS, we can ignore this message.

Now wizard extracts the hardware information (platform and chassis number) form selected IOS file and lists it in next screen along with an automatically populated device name.

If extracted information does not match with device, select the correct platform and chassis number from drop down. If require, you may also adjust the device name.

Verify / adjust the information and Click Next button to continue

Next screen allows us set the RAM size for this device. By default wizard automatically allocates the minimum recommended memory (RAM) for device. But if require, we can adjust it to match with our specific requirement.

If selected IOS belongs to a modular device, next screen allows us to install the interfaces in available slots.

Select appropriate interfaces and click Next button.

Just like interfaces slots, if selected IOS belongs to a device which has WIC modules, next screen allows to install the WIC interface in WIC slots.

Select the desire WIC interface and click Next button

Next screen allows us to put a limit on CPU usage by this IOS. We should always specify this value. This value prevents a faulty or buggy IOS from consuming entire CPU cycles. Once this value is configured, GNS3 does not allow IOS from consuming CPU beyond this limit.

Click Idle-PC finder button and use the suggested value in this field.

Click Finish button to close the wizard
