Hi,
LibreNms allows you to display the list of errored ports, which is very useful.
Unfortunately, the duplex information is not part of the displayable information (not in the default screen, nor in the drop-down list of displayable columns).
A half-duplex port will generate many “normal” collisions that LibreNms considers to be errors. The port duplex information is therefore important information for determining the cause of errors.
Can you add the duplex to the list of displayable fields on the errored ports screen?
It seems likely (I’ve tested it in my environment) that all you need to do is add the “ifDuplex” information to the following files:
/librenms/includes/html/pages/ports/list.inc.php
/librenms /app/Http/Controllers/Table/PortsController.php
Thanks,
