A VLAN represents an isolated layer two domain, identified by a name and a numeric ID (1-4094) as defined in IEEE 802.1Q. Each VLAN may be assigned to a site, tenant, and/or VLAN group.
Each VLAN must be assigned one of the following operational statuses:
As with prefixes, each VLAN may also be assigned a functional role. Prefixes and VLANs share the same set of customizable roles.
VLAN groups can be used to organize VLANs within NetBox. Each group may optionally be assigned to a specific site, but a group cannot belong to multiple sites.
Groups can also be used to enforce uniqueness: Each VLAN within a group must have a unique ID and name. VLANs which are not assigned to a group may have overlapping names and IDs (including VLANs which belong to a common site). For example, you can create two VLANs with ID 123, but they cannot both be assigned to the same group.
