Even after increasing number of segments used from 16 to 128 which is the prerequisite to increase the number of VLANs creation within the enterprise (this feature subscription Based and need Premium category ), error message appears that you can't add more than the default limitation "32", as per below example:
VCO/VECO (VeloCloud orchestrator)
VCE (VeloCloud Edge)
This feature is interdepended on a system properties on VCO that needs to be set to 128, but this would be over the whole VCO.
The Default system properties is 16 value and need to be changed to 128 to change the default behavior
1-Create support case
2-Refer to this KB
3-Wait for applying the change on VCO (change the system properties needed )in order for applying the feature's configuration change.
This feature need Edge to be at least 5.2 in order to accept more than 32 VLANs.
You can download the datasheet to confirm that this feature is subscription based feature because it depends on number of segment :

On-prem setup can get the benefit from this by applying the same change using superuser operator account
