In-Place Upgrade

You may upgrade from CML 2.0 to CML 2.1 without performing a full re-installation.

See Upgrading to CML 2.1 for more information about upgrading.

Bare Metal Installation

You have the option to do a bare metal installation of CML 2.1 instead of deploying this release as a VM.

See also Installing CML 2.1 and New and Changed Features in CML 2.1.

UI Updates and Usability Improvements

CML 2.1 incorporates many updates and fixes the HTML5 browser-based user interface (UI). Note that the Lab Manager is now called the Dashboard.

See New and Changed Features in CML 2.1 and Bug Fixes in CML 2.1 for more details. See Cisco Modeling Labs User’s Guide for instructions on using the HTML5 UI.

Dark Mode

Dark mode uses a color scheme with a dark background color. The setting is persistent for your user.

The Dark Mode setting is available in the User Menu.

User Settings page

Non-admin users can change their own passwords on this page.

The Settings page can be accessed from the User Menu.

Administrator Access

Application administrator accounts may now view and control other users’ labs.

See New and Changed Features in CML 2.1 and Bug Fixes in CML 2.1 for more details.

Packet Capture

The UI now provides a detailed packet display and the ability to download a PCAP file for the capture.

See the Packet Capture documentation for this feature.

Configuration Generation and Extraction

Build Initial Bootstrap Configurations and Extract Configs incorporate a variety of improvements to address issues seen with CML 2.0.

See New and Changed Features in CML 2.1 and Bug Fixes in CML 2.1 for more details.

Support for mutli-disk VMs

CML 2.1 includes support for VMs that require multiple disks. The feature enables you to add third-party VMs that use multiple disk images to your CML server.

See Custom VM Images for documentation on adding custom images to your CML server.

CPU Limit and Launch Sequencing

The new release incorporates various changes to the launch sequencing. Small labs should start faster, and it may be possible to start larger labs on your existing hardware than CML 2.0 would run.

See the Launch Sequencing and CPU Limits documentation for this feature.

Node and Image Definitions

These pages are newly updated and incorporate changes for other features, such as multi-disk VMs and CPU limits.

See Creating A New Node Definition and Preparing a Custom Image for documentation on adding or modifying node and image definitions.

DHCP Snooping

We improved the DHCP snooper, and it will now also work on IPv6-only network segments. The API should return an IP address for any node that has successfully acquired an IP address.

Link Conditioning

You can set properties on a link without using an extra WAN Emulator node between two nodes.

See the link’s Simulate pane in the Workbench. This feature is also available via the APIs and Client Library.

API and Client Library Updates

New and updated API endpoints expose new functionality in CML 2.1. The Client Library also provides licensing support.

See Tools ‣ API Documentation or Tools ‣ Client Library in the CML UI for documentation about the updated APIs.
