A fully functional version of IOS called Cisco Iou images on unix (IOU) runs as a user mode unix process. IOU is an application that runs like any other because it is created as a native Solaris image.

IOU/IOL images from Cisco with an IOURC licensing file. On Linux/Unix, images are known as IOL or IOU. Save and upload an IOL/IOU picture. You must first download the IOU IOL pictures from the EVE-NG server. Next, upload the IOL image you want to run to EVE-NG. 

IOL can only be utilized by Cisco personnel or authorized customers because it is an internal IOS version. Upload the image you downloaded.

• Activate the GNS3-IOU.
• Launch the VM.
• You will see an IP address appear above the console screen after it has started.
• Click the upload button after picking out the L2 and L3 IOU photos one at a time.
• Now launch GNS 3.
• IOS on Unix, click.

When compared to VIRL, both features are improved with GNS3 and EVE-NG. We discover that GNS3 is a free, open-source community that has created a well-documented piece of software when comparing it to EVE-NG.

Cisco iou images are L2/L3 copies of switches and routers that allow you to practice with L3 devices while preserving their features and functionality. Although Cisco IOU/IOL images were initially distributed for testing and architecture purposes, they are now used for CCIE routing and switching practice. 

Enables self-healing security and networking to defend devices, data, and applications throughout the extended digital attack surface and cycle. provides complete real-time cybersecurity protection from users to applications by combining the concepts of convergence and consolidation.

The fortinet labs, which allows granular use cases with more deployment patterns than any other solution, is powered by a single operating system. These environments consist of physical, virtual, cloud, and X-as-a-Service. Additionally, it covers the broadest ecosystem and product line in the sector, encompassing endpoints, networks, and clouds.

Fabric Security From Fortinet. This makes it possible to quickly and effectively detect and enforce attacks over the whole attack surface. The Security Fabric automatically makes adjustments based on ongoing risk assessments in order to counter the most recent known and unknown threats in real time. models of artificial intelligence and machine learning developed by Fortinet Labs. Unified data sets originating from networks, endpoints, and clouds, in-depth independent research, and extensive industry collaboration all contribute to this.
