netbox-interface-view

NetBox Plugin for viewing device interfaces in a stylish grid layout that mimics the physical port arrangement.

Features

• Grid Visualization: Display device interfaces in a configurable grid layout (rows × columns)
• Visual Connection Status: Color-coded indicators show interface connection and enabled status
• VLAN Color-Coding: Interfaces are color-coded based on their VLAN assignments
  • Border color represents the untagged VLAN
  • Colored dots represent tagged VLANs
• Interface Filtering: Filter out specific interface types (e.g., Virtual, LAG, Loopback)
• Configurable Layout: Grid dimensions can be configured per device using custom fields

Installation

1. Install the plugin:

pip install netbox-interface-view

2. Add the plugin to your NetBox configuration (configuration.py):

PLUGINS = [
    'netbox_interface_view',
]

3. Run database migrations:

cd /opt/netbox/netbox/
python3 manage.py migrate

4. Restart NetBox services:

sudo systemctl restart netbox netbox-rq

Configuration

Custom Fields Setup

The plugin requires the following custom fields to be created in NetBox:

Device Custom Fields

1. grid_rows (Integer)

   • Content Type: dcim > device
   • Type: Integer
   • Default: 2
   • Description: Number of rows in the interface grid

2. grid_columns (Integer)

   • Content Type: dcim > device
   • Type: Integer
   • Default: 24
   • Description: Number of columns in the interface grid

VLAN Custom Fields

1. color (Text)
   • Content Type: ipam > vlan
   • Type: Text
   • Default: #cccccc
   • Validation: Hex color code (e.g., #FF5733)
   • Description: Color to use for VLAN visualization (hex color code)

Creating Custom Fields via NetBox UI

1. Navigate to Customization > Custom Fields
2. Click Add to create a new custom field
3. Fill in the details as specified above
4. Save the custom field

Creating Custom Fields via API

You can also create custom fields programmatically using the NetBox API or Django shell.

Usage

1. Navigate to a device detail page in NetBox
2. Click the "View Interface Grid" button (appears in the device header)
3. The grid visualization page will display:
   • A configurable grid of interface cells
   • Connection status indicators (green = connected, gray = disconnected, red = disabled)
   • VLAN color coding (border = untagged VLAN, dots = tagged VLANs)
   • Filter options to exclude specific interface types

Example Configuration

For a 48-port switch with ports arranged in 2 rows:

• Set grid_rows = 2
• Set grid_columns = 24

For a 24-port switch with ports arranged in 3 rows:

• Set grid_rows = 3
• Set grid_columns = 8

Legend

• Green dot (●): Interface is connected and enabled
• Gray dot (●): Interface is disconnected
• Red dot (●): Interface is disabled
• Border color: Represents the untagged VLAN color
• Small colored dots: Represent tagged VLANs

Requirements

• NetBox >= 3.5.0
• Python >= 3.8
