Does new Multi-object Cable Terminations not fully supported breakout cable?

[gamerslouis]

I notice that v3.3.0 add the the feature Multi-object Cable Terminations (#9102)
The description show that this can be used to modeling breakout cable.

So I try to create cable connection from one device interface to another "two devices" interfaces.
But I found that the "connect cable ui still design to connect only between one device and another one.
It seems that I can't select two interfaces from two device at "B Side"

However, if I select interfaces on one device and switch B Side device field to another device, then I can select interfaces from two device since the interfaces field is not cleared if the device field change.

After that I can get a weird trace graph and cable view

In this case, termination B contains interfaces:
- dmi01-akron-sw01 GigabitEthernet1/0/13
- dmi01-akron-sw01 GigabitEthernet1/0/14
- dmi01-akron-sw01 GigabitEthernet1/0/15
- dmi01-camden-sw01 GigabitEthernet1/0/7
- dmi01-camden-sw01 GigabitEthernet1/0/11

Then I try to remove akron GigabitEthernet1/0/13 and camden GigabitEthernet1/0/7 by edit cable then I get a AssertionError.

This is a limitation of how the trace is being rendered. We'll to tweak the SVG rendering logic to clarify the device-to-component associations.

Then I try to remove akron GigabitEthernet1/0/13 and camden GigabitEthernet1/0/7 by edit cable then I get a AssertionError.

This would be a separate issue. Please open a bug report if you're able to provide complete reproduction instructions.

Thank you for your reply!

I think that there is another UI issue.

This cable connect to five interfaces belonging to two different device.

But in cable page and connect cable page, it doesn't show these. It like that five interface all belong to single device.

I think the template should be modified, and one possibility can be

I am not sure if this match Netbox ui style and easy to identify.
Should I open a issue for this problem?

This solution does not work in the latest version v4.0.6. Is multiobject cable terminations still possible?

[candlerb]

Which solution, and what is your problem? Yes, multiple cable terminations to different devices do work in v4.0

[Joelp]

can I ask you for a link to documentation, or hint how to do cable multi termination to different devices? Only I know is how to createcable with one device on A side and one device on B side.

I need to connect breakout cable to device A (40G) and 4 different devices on side B (10G).

There's a description in #10841 (and discussions which reference that issue, e.g. #15175). However that issue says that the entry form has been changed.

A quick test with the entry form in 4.0.6 and I can't see how to make it work either; whenever you choose a new device, the list of interfaces is cleared.

I suggest you raise this as a bug. Give the exact set of steps you're trying to do, and screenshots before and after the interface list is cleared.

Please see #16176. It's currently open for volunteers.
