Deployment Type

Self-hosted

NetBox Version

v4.10.0

Python Version

3.10

Steps to Reproduce

  1. Create device A on rack. This device its going to have 2 rear ports and 2 front ports. Each rear port to one front.
  2. Create device B in another rack. This device should be the same as A. He will have 2 rear ports and 2 fronts. Each rear port to one front.
  3. Now connect the 4 rear ports with the same cable.
  4. Create a device in the same rack whre is located the device A. This device needs to have 1 interface.
  5. Now connect the 2 fronts ports from device A to this interface. this will cause an error.

Expected Behavior

It should make the connection and not give any error. I want to have 2 front ports connected to one interface. In my solution 2 fronts ports its just one cable but with two plugs (4 pglus if you count the two ends).
issue ex

I tried this simulation in the demo version of netbox too, and it give me error there too.

Thank you for opening a bug report. I was unable to reproduce the reported behavior on NetBox v4.1.0. Please re-confirm the reported behavior on the current stable release and adjust your post above as necessary. Remember to provide detailed steps that someone else can follow using a clean installation of NetBox to reproduce the issue. Remember to include the steps taken to create any initial objects or other data.

Ok, i will make the simulation again setp by step and then i will comment here the tutorial the most explainable possible. I will try to make this tomorrow.

@Zidrenn This assertion error is often caused by a mismatched number of "splits" in a cable path, ie different number of interface-front-rear<->rear-front-interface positions somewhere in the path, FYI

I think its easier if i show you what i want to documentate. Im gonna attach an example image.

netbox problem

I cant do this today, in every method that a tried i get errors.
In my netbox platform i already have ervery device for tests and i have all the middle connections done (rear with rear ports and that passive patch on C-FIBER.PATCH.PANEL. I dont have the interfaces connections because its when i get the error.

This is the error i get:
