NetBox Version

v4.4.8

Python Version

3.12

Steps to Reproduce

  1. Create at least 101 VLANs
  2. Assign all 101 VLANs as tagged VLANs to an interface
  3. Go to the WebUI for the interface in question and scroll down to the VLANs table
  4. Count the VLANs

Expected Behavior

All tagged VLANs assigned to the interface should show in the table.

Alternatively, there should be a message indicating that the list has been truncated, or some sort of pagination.

Observed Behavior

Only 100 VLANs are displayed in the list, and there is no hint that the list has been truncated.

@pv2b commented on GitHub (Dec 18, 2025):

It appears this behaviour is tied to the "page length" user preference. Setting it to 1000 will allow up to 1000 (I assume) VLANs to be shown, and setting the Page Length to a lower value (e.g. 25) may make it easier to reproduce.
