Issue when tracing a cable

[letienne]

Dear all,

We're running netbox v3.5.2 and are having issues when tracing a cable across multiple hops.

Tracing cable A --> B --> C --> D works fine, but tracing D --> C --> B --> A throws a "Path Split, please chose one path" at the "B" level, but with only one path available to choose from, so not really a choice.

We tried recreating all paths ( python3 netbox/manage.py trace_paths --force), but the result remains the same. We tried deleting all paths from the CLI, and regenerating them, but the issue persists as well (via >>> CablePath.objects.filter().delete())

Does anybody have any idea on how to troubleshoot (and hopefully fix) this issue?

Unfortunately, we won't be available to upgrade for a few months to test with the latest release, so I'm hoping that this can be fixed in DB or CLI.

Thanks and best regards,

Our issue was due to rear ports having multiple "positions" defined in some cases. Someone created a patch panel with port 1 having 1 position, port 2 having 2 positions, etc. Setting everything back to normal (1 position per port), and running trace_paths --force fixed our issue.
