Ports not visible under "Device -> Ports" (but exist elsewhere)

[pengembaratemporer]

Hello,

I’m experiencing an issue where ports are not showing under the device ports page for some equipment.

Problem

• When accessing:

  • Devices -> <device name> -> Ports

  • Example: https://<librenms>/device/9/ports
    → No ports are displayed

• However:

  • I can access individual ports directly via URL
    Example: https://<librenms>/device/device=9/tab=port/port=175/

  • Ports are visible under:

    • Ports -> All Ports

    • Device Overview (shows correct counts):

      • Total: 47

      • Up: 40

      • Down: 2

      • Disabled: 0

    • “Overall Traffic” section also lists the ports

Notes
Discovery and polling seem fine (ports counted correctly)
Issue appears specific to UI rendering under device port tab
Happens only on some devices

Has anyone encountered this before or knows what could cause the device ports page to show empty while data exists?

Thanks in advance!

Try the options in the menu top right when on the device port page

Thanks,

Previously all are unchecked.
Then i tried checked all, and the ports are shown.

Then i try to unchecked all again, and now it still shown.
