Originally created by @ognjen011 on GitHub (May 19, 2020).

Environment

  • Python version: 3.6.9
  • NetBox version: 2.8.4

Steps to Reproduce

  1. When i run bulk import interfaces on a set of multiple devices i keep seeing this error:The fields device, name must make a unique set.
  2. Step two would be to update interfaces once created but i the first job never finishes.

Expected Behavior

Expected behaviour is that the interfaces are created. This used to work fine prior to 2.8.0 as far as i can tell because that is how i populated most of my netbox install.

Observed Behavior

Observed behaviour import hangs indefinitely and multiple errors pop up: The fields device, name must make a unique set.

I have a python script that creates a default interface using napalm to get a list of interfaces from my devices in netbox.

    device_id = get_device_id(f"{host}", netbox)
        netbox.dcim.create_interface(
           name=f"{interface_name}",
           interface_type=1000,
           device_id=device_id,

Which is now failing with connection.py", line 121, in post
raise exceptions.CreateException(resp_data)
netbox.exceptions.CreateException: The fields device, name must make a unique set.
