VLANide

VLANide is a software framework and toolset designed to simplify the management of virtual local area networks (VLANs) by providing an integrated development environment for network engineers. It combines traditional VLAN configuration with development‑style workflows, enabling template‑based design, validation, and automated deployment of VLAN policies across multi‑vendor networks.

Key capabilities include centralized policy creation, version‑controlled VLAN templates, simulated lab testing, automatic conflict detection, and change auditing. VLANide supports multi‑vendor device connectors, allowing configurations to be generated for switches and routers via standard protocols such as NETCONF, RESTCONF, or SSH‑based CLI, and it stores state and policies in a structured data model.

Architecture comprises a core engine that coordinates templates and policies, a repository for version control, and adapters to network devices. The data model typically represents VLAN IDs, names, tagging modes (access or trunk), subnets, and access control rules; it can integrate with external directories for RBAC and with CI/CD pipelines for automation.

Typical use cases include large campuses, data centers, and service provider networks seeking repeatable VLAN provisioning, change management, and easier auditing. It supports design‑time simulation and what‑if analysis to prevent conflicts such as overlapping VLAN IDs or inconsistent tagging across devices.

Limitations and considerations include dependency on hardware programmability and correct device support, the potential for misconfiguration without thorough validation, and the need for strong security controls and access restrictions. As a relatively new approach, interoperability and community support continue to evolve.
