How to Model Multiple locations to a single VLAN

[jc-chuckles]

I'm new to Netbox and need some guidance please.

We have a campus network which has 30+ network cabinets of varying sizes, everything from a single 48 port switch to six X 48 port switches.

Dependant on size some cabs share the same VLAN.

My first stab at modelling this was to do site and then location being the cab id and then trying to tag the VLAN and Prefix to the cab. This works for a single cab location to single VLAN relationship but I've been unable to create a multiple cab locations to a single VLAN.

Is there a way of tagging a single VLAN to multiple locations and if not how can I model how our network is built?

Any help would be much appreciated.

Thanks

Same issue here. IT installed two ONTs on the same splitter and two different locations share the same VLAN and ultimately the broader subnet. Can it please be one to many?

We just use global vlans definitions and if they are globally scoped we make sure they are unique and put it in a custom field that they are global. Otherwise we assume vlans are local scoped by default without assigning them to locations.

We do scope them per VRF though.

The easiest solution at the moment I've found to this is tag all the VLAN's to a VLAN group and there corresponding prefixes and added a custom field that holds their Cab ID's, its not ideal but works.
