VlanGroup - ArrayField rather than a start/end range

[PieterL75]

NetBox version

v3.2.5

Feature type

Change to existing functionality

Proposed functionality

a VLAN Group has the option to limit the vlans that can be used in that group.
This FR is to make the vlan-member a comma-separated value and allow more that one range or separate vlans in a vlan group.

Use case

We have use cases where one group consists of 2 different ranges (1000-1099, 2500-2599 for example).
Currently we have to create a second group, or extend the vlangroup with vlans that should not be used in that group.

Database changes

• Remove the min_vid, max_vid values
• Replace with a ArrayField of Vlan/VlanRanges ?

#9083 proposed something similar, but the transition to a single ArrayField seems more efficient.

Need to put a bit more thought into how best to implement this. We do something similar with rack reservation units, however in that case we're actually storing a discrete integer for each rack unit to which the reservation applies. This doesn't scale well to ~4K VLAN IDs. We may be able to leverage an array of PostgreSQL range fields, but further research is needed.

While I would have liked to pursue this in v3.3, we're running a bit behind with this release as it is.

Hello Jeremy,
I wanted to know if this scenarios can be supported in this next iteration this range functionality. :

1. Creation of several vlan ranges, that can be assigned to the a vlan pool.
2. Each vlan range, can be defined with a separate status field to be configurable ( active, reserved.. )
3. A vlan pool, can include several different ranges

I would say that the vlan range can be a separate model itself where additional information can also be added to this object, like comments, or even the change log to monitor changes in the range definition.

Is it possible to take this up in v3.5?

It might be possible to employ an ArrayField of RangeFields.
