netbox-circuit-prefix-link

A NetBox plugin that links Circuits to Prefixes.

• One Circuit can have many linked Prefixes.
• Each Prefix can be linked to at most one Circuit.
• The link is surfaced as a panel on Circuit, Prefix, and IPAddress detail pages.

Compatible with NetBox 4.5.x and NetBox 4.6.x.

Install

pip install netbox-circuit-prefix-link

Then in your NetBox configuration.py:

PLUGINS = [
    'netbox_circuit_prefix_link',
]

Run migrations:

python manage.py migrate netbox_circuit_prefix_link

REST API

Endpoint: /api/plugins/circuit-prefix-link/circuit-prefixes/

Supports the standard NetBox CRUD plus filtering by circuit_id and prefix_id.

UI

• Circuit detail page — "Linked Prefixes" panel with an Add Prefix button.
• Prefix detail page — "Circuit Link" panel showing the associated Circuit (if any), with Link / Edit / Unlink buttons.
• IPAddress detail page — Read-only panel showing the Circuit of any parent Prefix that has a link.

Permissions

Standard Django/NetBox model permissions:

• netbox_circuit_prefix_link.view_circuitprefix
• netbox_circuit_prefix_link.add_circuitprefix
• netbox_circuit_prefix_link.change_circuitprefix
• netbox_circuit_prefix_link.delete_circuitprefix

Panel content is filtered with NetBox's object-permission restrict() — users only see Circuits and Prefixes they have view permission on.
