Deployment Type

NetBox Cloud

NetBox Version

v4.1-beta1

Python Version

3.10

Steps to Reproduce

1. Create a VLAN group allowing VIDs 1 through 200 (inclusive)
2. Create a VLAN with VID 1 inside the group
3. View the group's utilization

Expected Behavior

The VLAN group should report a utilization of 0.5% (1 / 200).

Observed Behavior

The VLAN group utilization is reported as 0.0%.

If we change the group's VLAN range to 1-100 (inclusive), its utilization is then reported as 1.0%.
