NetBox Device Type Import

This library is intended to be your friend and help you import all the device-types defined within the NetBox Device Type Library Repository.

Tested working with NetBox 3.2+ through 4.5+ (weekly CI run against NetBox main)

---

⚠️ direnv users — This repo ships a .envrc.example file. If you use direnv, review the file before enabling it:

cp .envrc.example .envrc
cat .envrc          # confirm it only loads .env vars and syncs uv
direnv allow

The file exclusively loads variables from .env into your shell and runs uv sync to keep dependencies up to date. Your .envrc is git-ignored.

Description

This script will clone a copy of the netbox-community/devicetype-library repository to your machine to allow it to import the device types you would like without copy and pasting them into the NetBox UI.

Getting Started

1. Install dependencies with uv:

   uv sync

2. Copy .env.example to .env and fill in your NetBox URL and API token (the token needs write rights):

   cp .env.example .env
   vim .env

3. Run the script:

   uv run nb-dt-import.py

Usage

Running the script clones (or updates) the netbox-community/devicetype-library repository into the repo subdirectory, then loops over every manufacturer and device, creating anything that is missing from NetBox while skipping entries that already exist.

Arguments

This script currently accepts a list of vendors as an argument, so that you can selectively import devices.

To import only device by APC, for example:

uv run nb-dt-import.py --vendors apc

--vendors can also accept a comma-separated list of vendors if you want to import multiple.

uv run nb-dt-import.py --vendors apc,juniper

Update Mode

By default, the script only creates new device types and skips existing ones. To update existing device types:

uv run nb-dt-import.py --update

This will:

• Add new components (interfaces, power ports, etc.) that are in YAML but missing from NetBox
• Update properties of existing components if they've changed
• Update device type properties (u_height, part_number, etc.) if they've changed
• Report components that exist in NetBox but are missing from YAML (won't delete by default)

Component Removal (Use with Caution)

WARNING: Removing components can affect existing device instances in NetBox.

If you've changed a device type definition (for example, converting interfaces to module-bays to support SFP modules), you can remove obsolete components with:

uv run nb-dt-import.py --update --remove-components

This will delete any components (interfaces, ports, bays, etc.) that exist in NetBox but are no longer present in the YAML definition.

Use cases:

• Converting fixed interfaces to module-bays for modular devices
• Removing incorrectly defined components from device templates
• Cleaning up after major device type definition changes

Important considerations:

• Components attached to actual device instances may prevent deletion
• Review the change detection report before enabling component removal
• Test on a staging NetBox instance first if possible
