The REFPLAT (Reference Platform) ISO file is a critical component of any CML deployment. When you download the CML controller (either as an OVA file for virtual machines or as an ISO for bare-metal servers), you are essentially getting the platform's operating system and management interface. It comes with only a few default node types (like an “Unmanaged Switch” or “External Connector”) because the complex images of routers and switches are not bundled with the base system. The REFPLAT ISO steps in to provide the actual "firmware" that powers all the simulated networking devices.
Cisco Modeling Labs (CML) is the premier network simulation platform for engineers looking to design, test, and troubleshoot complex topologies. At the core of CML is the Reference Platform (Refplat) ISO. This file contains the virtual machine images for Cisco operating systems like IOSv, IOS-XE, NX-OS, and ASA.

CML is paid software. It requires a valid license (Smart License via Cisco DNA Center or an on-premises license file). Some enterprising individuals release "patched" ISOs or Python scripts that modify the CML source code ( /usr/local/cml/... ) to disable license checks. Using these is a direct violation of Cisco's EULA (End User License Agreement). Cisco actively detects these via telemetry, and your access to software updates via Cisco.com will be revoked if caught.
The RefPlat ISO is a virtual DVD image containing the actual operating systems for Cisco and third-party network nodes. When you boot a router or switch in CML, the system maps this ISO to spin up the virtual machine. Core Component Breakdown
This article serves as a comprehensive guide to the CML RefPlat ISO—what it is, how to download official copies, the installation process, and a deep dive into the controversial world of "patched" (modified) versions found in online communities.
