Steps to Reproduce

• I created switches, then created the interfaces.

• I also created the patch panels that connect the switches to the PCs. On the patch panels, I created rear ports, followed by front ports.

• Then, I created the PCs.
• I created a cable to connect a switch interface to the front port of the patch panel.
• I also created a cable to connect the rear port of the patch panel to the PC.

• The result is this trace.

• When everything is working, in the "Connection" column, I can see the switch and the port to which I am connected. I can also see the trace from the PC.

I have now created a script that retrieves data such as the hostname, the switch, and the port it is connected to. However, when these details change, I want everything to be reconnected to the correct switch.
Let me explain: let's say PC-1 is connected to Switch-1, Port-1. If my file is updated and the new configuration shows that PC-1 should be connected to Switch-2, Port-1, then I delete the termination on side A and patch it with the LAN0 interface ID of the PC I want to connect.

Script :
delete_response=$(curl -skX 'DELETE'
"https://netbox.""/api/dcim/cable-terminations/$a_termination_id/"
-H 'accept: application/json'
-H 'Content-Type: application/json'
-H "Authorization: Token "" ")

                                                                            echo $delete_response

                                                                            patch_response=$(curl -skX 'PATCH' \
                                                                            "https://netbox.""api/dcim/cables/$cable_id_rear_port/" \
                                                                            -H 'accept: application/json' \
                                                                            -H 'Content-Type: application/json' \
                                                                            -H "Authorization: Token "" " \
                                                                            -d '{
                                                                                            "a_terminations": [
                                                                                            {
                                                                                                            "object_type" : "dcim.interface",
                                                                                                            "object_id": '"$interface_id"'
                                                                                            }
                                                                                             ],
                                                                                               "status": "connected"
                                                                                            }')

• The script correctly deletes and reconnects.

I would like to clarify that when I delete the termination and reconnect it to the cable, it works. I get the trace, and in the "Connection" column of the PC, the switch and port it is connected to appear correctly.

Expected Behavior

• When the script deletes and reconnects the termination to the cable, it works, but the trace and the "Connection" column remain empty.

• But when I look at the trace from the switch, I can see all the links.

Observed Behavior

• I noticed that in the database, the path_id 1891 was deleted and not recreated, except for path_id 1893, but the latter allows seeing the trace from the switch.

@LeCooperTLC Can you please provide the reproduction steps in text instead of screenshots. I.E. The first part "I created switches, then created the interfaces." can you please list out the interfaces needed, for example:

1. create device name "xxx" with ...
2. On device xxx add an interface: name: interface1 ...

It allows us to quickly try and reproduce the issue without having to decode screenshots and figure out what you might have entered.

[LeCooperTLC]

I created a switch "Switch01", then added 54 interfaces from [01-54] of type 1000BASE-T.

Next, I created a patch panel "Panel01". I created rear ports [01-24] and front ports [01-24]. The rear ports are automatically detected (make sure to create the rear ports first).

Now, I go to my switch, select the interface I want, and click "connect cable" on the front port, then select my patch panel and connect the desired front port.

I create a PC "pc01", create an interface "LAN0" of type 1000BASE-T, then connect the cable to the rear port of Panel01.

Normally, after that, everything is properly connected and the trace is visible, but when the A-end of the cable connecting the PC to the patch panel is removed and patched, the trace disappears.

a_termination_id=$(curl -skH "Authorization: Token """ \
"https://netbox.""/api/dcim/cable-terminations/?cable=$cable_id" | jq -r '.results[0].id')

(This command allows you to get the ID of the A-end of the cable that connects the PC to the patch panel.)
