Downloading the latest Cisco Modeling Labs (CML) Reference Platforms (Refplat) ISO is essential for accessing the virtual images (like IOSv, Cat8000V, and ASAv) needed to run your lab simulations. Whether you are using the new CML-Free tier or a paid subscription, the process follows specific paths through the Cisco ecosystem. Where to Download

Verification:Always check the SHA512 checksum provided on the Cisco download page against your local file. A corrupted ISO will cause "Node Definition" errors inside CML, preventing your virtual routers from booting.

The most significant new helpful feature related to the Cisco Modeling Labs (CML) "refplat" (Reference Platform) ISO is the introduction of native IOS on Linux (IOL) images. This allows you to run routers and switches as lightweight processes rather than full virtual machines (VMs), drastically reducing CPU and memory consumption while enabling faster boot times. Key Features of New Refplat ISO Releases

Copy to Disk: Modern CML versions (v2.5+) require you to copy images from the mounted ISO to the local disk via the System Administration Cockpit under the CML2 > Maintenance section.

The "Refplat ISO" is a massive image collection (over 10GB) that acts as the lifeblood of your Cisco Modeling Labs (CML). Without it, you cannot start lab simulations because it contains the actual virtual machines (VMs) for routers, switches, and firewalls. The Core Essentials
