Restart the CML services or reboot the CML virtual machine to clear cached image structures. Troubleshooting Common Errors
Once your patched ISO is created, you must verify its integrity and upload it to your CML controller. Verify the ISO Integrity
Instead of sourcing unofficial files, you can modify, update, and patch your existing Refplat image set directly using built-in, officially supported tools. 1. Leverage the Cisco Software Central Portal cisco cml refplat iso download patched
If a patched node does not appear in your CML topology menu, check that the corresponding .yaml definition file was placed in the exact same folder as the .qcow2 image before compilation.
Distributed separately due to file size constraints, this ISO provides specialized appliances like Catalyst SD-WAN, Cisco ISE, and Firepower (FMCv/FTDv). Restart the CML services or reboot the CML
If the filename changed, you must modify the corresponding YAML or JSON node definition file within the workspace to point to the new filename. 5. Step 4: Recompiling the Patched RefPlat ISO
Searching for third-party, pre-patched, or modified Refplat ISO files exposes your environment to severe vulnerabilities: If the filename changed, you must modify the
: Provides advanced nodes like SD-WAN and FTD that are often released between major CML versions. The "Patched" Intent
Without this ISO, you cannot start any meaningful network simulation. The system will display "CL Nodes Do Not Show Up" or simply have no devices available in the design panel, because the core images required to power those devices are missing.
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.
If you have access to Cisco CCO downloads, you can obtain newer .qcow2 files for specific platforms (e.g., a newer NX-OSv image).
