What is netstage?

NetStage is a Python command-line tool for network engineers and system administrators who need to discover devices on a network and generate configuration scripts for network switches and routers. It handles two distinct jobs: scanning a network to find what is out there, and producing ready-to-use configuration code in the syntax each vendor expects. The discovery side works by sending ping signals to every address in a local network range, using 64 simultaneous threads to finish a full scan in under five seconds. Once it finds active devices, it probes common management ports to determine whether each device responds to SSH, Telnet, HTTP, or HTTPS. This helps identify which devices are actual network hardware rather than ordinary computers. The configuration side takes a design you specify through an interactive setup wizard and compiles it into working command-line syntax for Cisco IOS-XE equipment or Juniper Junos equipment. You can define VLANs, port groupings, management gateways, and security settings in one place, and the tool produces a correctly formatted script for each vendor. The output is saved as a text file you can load directly onto the device via a console connection. Installation requires Python 3.8 or newer. You clone the repository, optionally create a virtual environment, install the listed dependencies, and run a single Python file. The project is MIT licensed and accepts contributions. The README notes that support for additional vendors such as Arista and HP ProCurve could be added through pull requests.
