Perform Risk-Free Network Analyses

Design, build, visualize, and launch virtual network simulations quickly and efficiently. With Cisco Modeling Labs, you can model your network behavior, validate network changes, and troubleshoot issues. Cisco Modeling Labs acts as a test bed for applications that work with the network. With its simple point-and-click interface, you can design or import a network topology and turn it into a virtual network in minutes.

Cisco Modeling Labs

Cisco Modeling Labs 1.5 has now been released for purchase and upgrade.

Features and Capabilities

Cisco Modeling Labs is a scalable and extensible software platform for designing, simulating, and testing network models. This innovative platform uses advanced virtualization technology, such as OpenStack, for simulations. It combines that virtualization technology with the technology of Cisco reference platforms such as Cisco IOSv, NX-OSv 9000, IOS XRv 9000, IOS XE (CSR 1000V) and ASAv to provide a wide range of network modeling options. Cisco Modeling Labs is an ideal solution for conducting predeployment network testing.

With the new clustering architecture, Cisco Modeling Labs is ideal for service providers and enterprise use.


With Cisco Modeling Labs, you can:

  • Create models and what-if scenarios for real-world and future networks.
  • Automatically generate configurations.
  • Visualize protocols.
  • Use Cisco IOS network operating systems with routers and switches.
  • Connect virtual and physical environments.
  • Run third-party images within the simulation.


Network engineers with minimal to intermediate networking knowledge can take advantage of Cisco Modeling Labs Corporate Edition. Benefits include:

  • On-premise application
  • Increased uptime with what-if scenarios
  • Decreased deployment time of new services
  • On-demand access to resources
  • Hands-on experience and training
  • Reduced lab footprint to be more green

Typical use cases include:

  • Design and simulation of network changes
  • Pretesting network updates prior to physical deployment
  • Test bed for application and device network interfacings
  • Simulation of production networks and troubleshooting in a simulated network
  • Internal operator practice with a virtual network
