For network automation and traffic generation. How to Find and Download the New Refplat ISO
Updating or downloading a new Cisco CML Refplat ISO is the best way to keep your home lab or corporate testing environment aligned with modern production environments. By safely downloading the package through Cisco Software Central, verifying its integrity, and copying the files directly to your VM's local storage, you ensure the fastest boot times and most reliable performance for your network simulations.
Cisco Modeling Labs (CML) is a network simulation platform that allows you to design, configure, and test network topologies. The RefPlat ISO is a reference platform image used in CML to simulate various network devices.
The nodes extracted from the refplat ISO are resource-heavy. Ensure your underlying server has ample RAM and CPU cores. A good rule of thumb is to dedicate at least 32GB to 64GB of RAM if you plan to run large enterprise topologies. cisco cml refplat iso download new
Cisco Modeling Labs (CML) requires a Reference Platform (refplat) ISO
The is an essential file for anyone using Cisco Modeling Labs (CML) . It contains all the virtual machine (VM) images needed to run specific node types within your lab simulation, such as Cisco IOSv, IOS XE, Catalyst 8000V, and ASAv. Without these images, you cannot start any simulations.
When you visit the Cisco download portal, you may see multiple RefPlat ISO files. It's crucial to understand the differences to download the correct one for your needs: For network automation and traffic generation
If you are deploying CML for the very first time using VMware Workstation or ESXi, you can map the ISO directly to the virtual machine before powering it on.
If you already have CML running, you can download RefPlat directly from the UI:
