Cisco Modeling Labs (CML) version 2.7 brings an array of new features designed to enhance simulation flexibility, user experience, and network design capabilities.<\/p>

Cisco released this version on the 27th of March. It is not yet the recommended release but from my experience worth trying!\u00a0<\/p>

The CML team has released a webinar about their new features. If you don’t have time to watch the full video, you can read on for a summary. \ud83d\ude09<\/p>

Here\u2019s a detailed look at these features and how to update your CML environment to leverage these improvements. \u23e9\ufe0f\u00a0 \u23e9\ufe0f\u00a0 \u23e9\ufe0f<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

\ud83c\udf1f The adjustable sidebar in CML 2.7 enhances the user experience by providing more workspace for editing configurations.
\ud83d\udd04 Multiple configuration files in CML 2.7 offer flexibility and enable expanding Day Zero configurations, catering to various use cases.
\u274c The removal of accidental double-click hiding of links in CML 2.7 prevents users from unintentionally hiding links and causing confusion.
\ud83e\udde9 The improved bundle links functionality in CML 2.7 allows for easier management and editing of individual links within a bundle.
\ud83d\udd12 The fixed annotation saving issue in CML 2.7 ensures that changes made to annotations are properly saved, preventing data loss.
\ud83d\udda5\ufe0f Node parameters in CML 2.7 provide customization options for specific nodes.
\ud83c\udf10 The ability to configure additional NAT networks in external connectors in CML 2.7 expands network setup possibilities and enhances network functionality.
\ud83d\ude80 The most impressive update is the new IOL IOS-XE image, which is a lightweight image based on Linux.<\/span><\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Now let’s talk about the upgrade process. You can update your existing environment in 3 simple steps:<\/p>

  1. Download the update package and upload it to your CML instance<\/li>
  2. Place the node in maintenance mode and the node status to READY<\/li>
  3. Start the upgrade process via the Ubuntu Cockpit\u00a0<\/li><\/ol>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    Login to your Ubuntu Cockpit which is available at https:\/\/your-ip:9090<\/a>. Once you are logged in to go CML > Software Upgrade<\/strong> and click on Upgrade<\/strong>.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    In the meantime, download the refplat iso.<\/p>

    Once the upgrade is done and the Cockpit interface is responding, mount the downloaded refplat iso (attach the iso to your VM in ESXi, in my case) which contains all the node definitions and node images.\u00a0<\/p>

    Click on CML2 > Copy Refplat ISO<\/strong><\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
