Track connection across multiple patchpanels

[FisoF]

Hello ,
Its possible to fully track connectin across multiple patch panels ?

Scheme:

Now result in netbox is:

Thaks for answer

It is totally possible to do what you showed on that picture. Looks like PatchPanel2 has not a corresponding front port for that rear port.

[joaolucasmacedo]

I think you are doing right but looks like Netbox has that limitation when you have a multi position segment on a cable trace.
See #10602
In theory it would work as you expected, so it looks like a bug.

I've done exact what you're trying to do recently and it works. Can you show what the cable between the front ports of patch panel 2 and 3 look like?

On my setup, between panel 2 and 3 I have one cable connected to both ports on both panels.

@CupcakeMunster my connection is same as your but... can you show your full trace ?

I recreated it in the demo site. If you check it out before tomorrow it'll probably still be there. Look for the location called "rats nest"

I think in this case you should have a 1:1 relationship with front-port to rear-port, so each strand/pair of the 12-count cable terminates in a distinct rear-port that matches a single front-port. I think the different positions are for MUXes where multiple strands of front-port fiber end up on a single strand of rear-port fiber, not for when multiple strands are bundled into a single cable. Or am I grossly misinterpreting what you are doing here? — Mark Tinberg ***@***.***> Division of Information Technology-Network Services University of Wisconsin-Madison

On PatchPanel2 I have 1 rear port with 12 positions (fiber optic cable terminated with splices) Its wrong way ? I must create connection between rear ports of patch panels "line by line", not one cable with multiple positions?

I think that the way @FisoF is doing is right, as I understand cabling modeling in Netbox. I should work for both MUXes and multi fiber cables.
See #10602

@mtinberg maybe you are right and I misunderstand cabling modeling(and different positions is realy only for MUXes/splitters https://www.peak-fiber.com/product/plc-splitter/ ) . Detailed description in documentation is missing... Or is it bug as @joaolucasmacedo says...

[mtinberg]

I'm reading through the doc and checking in the lab, I think the Positions number is used for MPO cables (and maybe also MUX) where multiple fiber strands are included in the same physical connector/port https://demo.netbox.dev/static/docs/models/dcim/rearport/ eg https://edgeoptic.com/kb_article/mtp-mpo-cables-all-basics-you-need-to-know/ where you aren't terminating each strand individually in the fiber patch, I suppose LC works that way too. — Mark Tinberg ***@***.***> Division of Information Technology-Network Services University of Wisconsin-Madison
