Cisco Modeling Labs (CML) relies on a Reference Platform (refplat) ISO to provide the virtual machine images—such as IOSv, NX-OSv, and ASAv—required to run network simulations. For users seeking a "patched" or most up-to-date version, it is essential to understand that Cisco typically releases cumulative ISO updates rather than individual patches for the ISO itself.

In the context of CML, "patched" usually refers to one of two scenarios:
Supplemental ISOs: Cisco sometimes releases a "supplemental" ISO (e.g., refplat-20241016-supplemental.iso) containing newer or specialized images like SD-WAN Controllers or Catalyst 9000v that were not in the base release.
Cumulative Updates: Newer CML server versions (e.g., 2.8 or 2.9) often come with a refreshed base ISO that includes the latest software fixes for the virtual images. How to Apply the Latest Refplat to Your CML Instance CML Installation Guide - Cisco Modeling Labs v2.9

It looks like you’re searching for a patched ISO for Cisco CML (Cisco Modeling Labs) — likely to bypass license restrictions or to run the older CML Personal / CML 2.x without a smart license.
I need to be direct:
Cisco does not authorize patched, cracked, or modified ISOs for CML. Distributing or using patched images violates Cisco’s software licensing agreement.
Here’s what you should know:
I cannot and will not provide links, instructions, or support for:
Why this matters:
CML allows unsupported image import via the GUI. You can legally add:
You do not need a cracked ISO for this. Just upload the image files via the CML web interface.
Disclaimer: This content is for educational purposes only. Downloading, modifying, or distributing patched Cisco software violates Cisco’s End User License Agreement (EULA) and applicable copyright laws. Always use official, licensed images. I do not host, link to, or condone the use of cracked software.
If you're a licensed user looking for help with legitimate installation issues (e.g., patching a known bug with an official hotfix from Cisco), please:
Bottom line: There is no legitimate "patched refplat ISO" for CML. If you see references to one online, it's almost certainly pirated software and using it carries significant legal and security risks. Pursue legal options instead.
The download had been stuck at 84% for three hours, a digital stalemate between a flickering DSL light and the vast, indifferent servers of the Cisco Software Central. For Elias, a network engineer whose home lab was held together by caffeine and sheer willpower, the "refplat" ISO was the holy grail.
The Cisco Modeling Labs (CML) Reference Platform ISO wasn’t just a file; it was the DNA of his virtual world. It contained the heavy hitters: the IOSv images, the hungry NX-OSv nodes, and the elusive ASAv firewalls. But the official release had a flaw—a bug in the node definitions that caused his spanning-tree topologies to collapse like a house of cards every time he tried to simulate a data center migration. You have a valid Cisco account and are
He had heard whispers on a defunct subreddit about a "patched" version. It wasn't a pirate copy—Elias had his legitimate license—but a community-maintained revision where the YAML definitions had been hand-tuned by engineers who had spent too many nights staring at packet captures.
He found the link on an obscure FTP server hosted out of a university in Brno. The filename was a string of alphanumeric poetry: refplat-20240312-patched-community-v3.iso.
As the progress bar finally nudged to 100%, Elias felt a rush of adrenaline. He mounted the ISO to his ESXi host and initialized the CML controller. The fans on his refurbished Dell PowerEdge roared to life, a mechanical scream that echoed in the small spare bedroom.
"Come on," he whispered, watching the console logs scroll by in a blur of white text on a black background.
Loading node definitions... [OK]Verifying image checksums... [OK]Starting bridge interfaces... [OK]
He logged into the dashboard and dragged three Nexus 9000v switches onto the canvas. He wired them in a triangle, a classic test of loop prevention. In the old ISO, the CPU would have spiked to 100% as a broadcast storm devoured the virtual backplane. He clicked 'Start.'
The icons turned green. He opened a console to Switch-1 and typed show spanning-tree. The output was beautiful. The blocking ports were assigned correctly. The convergence was instantaneous. The "patched" ISO had worked.
For the first time in weeks, the virtual world was stable. Elias leaned back, the blue light of the monitor reflecting in his glasses. Outside, the sun was beginning to rise, but in the simulated rack of his mind, the lights were finally blinking in perfect, synchronized harmony.
To download the patched Cisco Modeling Labs (CML) Reference Platform (refplat) ISO, you must access the Cisco Software Central portal with an active CCO account associated with a CML purchase or the CML-Free tier.
The "patched" versions are typically released to fix issues with specific images (e.g., the refplat-20201110-fcs.iso replaced the original 20201020 version to fix crypto issues in IOSv). 🛠️ Official Download Process Step 1: Log in to Cisco Software Download. Step 2: Search for "Modeling Labs" in the product sidebar. Step 3: Select the latest release version (e.g., CML 2.9). Step 4: Look for the "Reference Platform ISO" file.
Standard ISO: Contains base images like IOSv, IOSvL2, and NX-OSv 9000.
Supplemental ISO: Contains larger images like Catalyst 9800-CL or SD-WAN.
Step 5: Download the file—note that it is often a .zip archive that must be extracted to get the .iso. 📂 Current Versioning (as of April 2026) Latest ISO: refplat-20241016-fcs.iso. Supplemental ISO: refplat-20241016-supplemental.iso.
Verification: Always check the SHA512 checksum on the Cisco Download Page after downloading to ensure the file isn't corrupted. 🔄 How to Apply/Patch the ISO
