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.
To download the Cisco Modeling Labs (CML) Reference Platform (refplat) ISO
, including the latest updated or "patched" versions, you must access the official Cisco software portal using your Cisco Connection Online (CCO) ID Official Download Sources Cisco Software Central
: The primary location for all CML files, including the base and supplemental reference platforms. Cisco Learning Network Store : If you purchased CML-Personal , log in to your My Account cisco cml refplat iso download patched

: For the latest releases (e.g., CML 2.9), you can access images via the Cisco U My Subscriptions ISO Types & Updates Cisco Modeling Labs - Free - Cisco DevNet
Download the files for CML-Free from Cisco's Software Central (SWC) site. You do not need to download all of the files from a CML- Cisco DevNet 'refplat-image.iso' download - from where?

If your hardware is giving you trouble with the REFPLAT ISO, do not patch it. Use the OVF/OVA version.
This method avoids the "refplat" and "patching" headache entirely while remaining 100% legal and stable.
Cisco CML (formerly VIRL) is a network simulation platform that allows you to model Cisco networks. The refplat (reference platform) ISO contains the official Cisco IOS, IOS-XE, NX-OS, and other device images needed to run nodes in CML.
Before you search for shady "patched" downloads on torrent sites (which are often laden with cryptominers or backdoors), understand that an official, valid CML license is surprisingly affordable. Bottom line: There is no legitimate "patched refplat
Cisco offers CML Personal (previously CML-P) for approximately $199/year. This includes:
The keyword "patched" is the most dangerous and legally ambiguous part of the search query. Generally, there are three reasons why engineers look for a patched ISO:
Cisco Modeling Labs (CML) 2.0+ uses the RefPlat (Reference Platform) model. Instead of a monolithic VM, you download an ISO installer for the CML controller (Ubuntu-based) and separately source Cisco IOSv, IOSvL2, ASAv, CSR1000v, or XRv9000 images.
A “patched” ISO typically means one of three things:
None of these are sanctioned by Cisco. Using them will void support, may break lab reproducibility, and could expose your network to security risks.
