So in LibreNMS, the VDSL port comes in as “type VDSL”, as expected.
The code in includes/polling/ports.inc.php at line 737 makes it so that LibreNMS pulls items such as line attenuation etc etc EVEN when the port is showing as down.
All you need to do to fix this, is apply the same logic you have for ADSL to VDSL.
This is what I changed the file to make this work.
