# VLANs A Virtual LAN (VLAN) represents an isolated layer two domain, identified by a name and a numeric ID (1-4094) as defined in [IEEE 802.1Q](https://en.wikipedia.org/wiki/IEEE_802.1Q). VLANs are arranged into [VLAN groups](./vlangroup.md) to define scope and to enforce uniqueness. ## Fields ### ID A 12-bit numeric ID for the VLAN, 1-4094 (inclusive). ### Name The configured VLAN name. ### Status The VLAN's operational status. !!! tip Additional statuses may be defined by setting `VLAN.status` under the [`FIELD_CHOICES`](../../configuration/data-validation.md#field_choices) configuration parameter. ### Role The user-defined functional [role](./role.md) assigned to the VLAN. ### VLAN Group or Site The [VLAN group](./vlangroup.md) or [site](../dcim/site.md) to which the VLAN is assigned. ### Q-in-Q Role !!! info "This field was introduced in NetBox v4.2."
