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.
Cisco has transitioned from the older "VIRL" style images to modern, 64-bit virtual platforms. The newest downloads typically feature: Stable images for R&S labs. CML-IOS-XRv 9000: For service provider simulations.
CML is sold as a platform (the dashboard and engine) and the node definitions (the software images). Without the Reference Platform ISO, your CML installation is just an empty shell. The "new" versions of this ISO are significant because they include: Updated IOS-XE (Cat8000v) images. New SD-WAN controller nodes. Optimized NX-OS 9000v footprints. Security patches for ASAv and Firepower (FTDv). How to Access the Latest Download
Most individual users obtain CML through a Personal or Personal Plus license. Once purchased, your access is tied to your Cisco Connection Online (CCO) ID.
Copy the ISO to the /var/local/virl2/dropfolder directory via SCP.
Ensure your CML host has at least 50GB of free space before attempting the download and extraction. The ISO stays mounted, so it consumes storage permanently.
Pre-configured Linux nodes for testing automation scripts (Python, Ansible) within the topology.
Navigate to the Cisco Software Download portal. Search for "Cisco Modeling Labs" and look for the "Reference Platforms" section.
Ensure the ISO version matches your CML controller version (e.g., CML 2.7 requires the 2.7.x RefPlat ISO for full compatibility). Step-by-Step: Adding the New ISO to CML
