Cisco Modeling Labs is a network simulation platform for network engineers, students, educators, and enterprise teams. It provides an HTML5 interface for creating and managing virtual labs with Cisco and third-party virtual machine images. Typical uses include certification practice, teaching, topology testing, troubleshooting, and NetDevOps validation before production changes. Deployment options include virtual machines, bare-metal servers, clustered environments, and cloud tooling, with web, Linux, Windows, macOS, API, and self-hosted access.

The plan structure covers individual learning through larger organizational deployments. CML-Free is a single-user offering with up to five simultaneously running nodes, no license subscription requirement, and no time limit. Personal supports one user and 20 Cisco nodes, while Personal Plus supports one user and 40 Cisco nodes; both have fixed node capacity and community support. Enterprise adds multi-user functionality, clustering, and community and TAC support. Education is designed for educational and nonprofit learning institutions, uses licensing per concurrent user, and includes clustering plus community and TAC support. CML Cloud Phase 1 PoC provides a dedicated, cloud-hosted virtual lab with NAT external connectivity and is invite-only.

Platform and automation breadth are central strengths. REST-based APIs control lab and simulation lifecycles, while the Python client library supports automation workflows. Integrations include pyATS, Ansible, Terraform, Wireshark, Docker, KVM, and MCP-compatible AI tools. L3 NAT and L2 system-bridge connectivity extend labs outward, and packet capture can stream to Wireshark. Teams that need Cisco-centered virtual labs, repeatable automation, or multi-user deployment should consider CML. Those requiring physical-hardware emulation or discrete-event simulation should choose a different network simulation approach.

Cisco Modeling Labs pros and cons

  • Where it wins
    • Cisco and third-party images with browser-based lab management
    • REST APIs, Python automation, and integrations with pyATS, Ansible, and Terraform
    • Clustering, external connectivity, Wireshark streaming, Docker, and KVM support
  • Where it doesn't
    • Personal and Personal Plus are single-user plans with fixed node capacity
    • CML Cloud Phase 1 is an invite-only proof of concept
    • It does not emulate physical hardware or act as a discrete-event simulator
