Cisco Modeling Labs 2.2.1-b36 Sandbox v1

June 2021

Cisco Modeling Labs (CML) is a multi-purpose network virtualization platform that provides an easy way to build, configure, and test new or existing network topologies with an intuitive user interface (UI). CML enables customers to support critical missions, such as designing, training, release testing, and configuration staging, without the expense of buying and staging real network hardware. This demonstration requires familiarity with Cisco networking architecture and routing fundamentals.

IMPORTANT: This demonstration is a sandbox that runs within a virtual machine (VM) that contains 8 virtual CPUs and 32 GB of memory; therefore, the number of devices you can include in a single topology is limited. The number of topologies that can run concurrently is also limited. The actual number of devices and topologies varies depending on the devices used in the simulations.

Please also note that we recommend that you use bridge1 for external device connectivity and static IPs into devices using the following network parameters:

  • = gateway/ntp
  • = DNS1
  • = DNS2
  • DNS Domain = demo.dcloud.cisco.com


  • Scenario 1. Login to CML and Create a Simple Topology
  • Scenario 2. Access the Console in the running Devices
  • Scenario 3. Accessing the Device using Telnet from the Windows Workstation
  • Scenario 4. Enabling SSH and the Web-GUI for the Device
  • Scenario 5. Ending the Running Simulation
