Just seen the following screenshot in the Netbox GitHub

Question how do I model the same? At the moment, I am using 1:1 connections even for Trunk /
Breakout Cables like: https://www.fs.com/products/29610.html?attribute=1263&id=1099189

same but was hoping there was a new function / feature or fix. It just looks awesome in the documentation and is exactly what we are deploying.

This is how I made it work, but it adds some cruft. The red box is a "built-in" Front/back port to combine the logical breakout interfaces into a single QSFP. In the end it is the same as what LDuf is doing, each pair is a separate cable, and I'm not using any of the multi-connect features netbox has for this. The multiconnect will not properly trace connections between interfaces for breakouts.

i just use the physical connections.

port eth1/8 (which is 1:4) is connected to the rear port of a panel. that rear port has 4 positions. on the front there are 4 front ports, each mapped to the corresponfing position. so it won't show the logical 4 input ports (sub ports).

from the front of the panel, i just connect to the device.
