# 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.

## Bulk Creation

Multiple VLANs can be created at once by selecting the "Bulk Create" tab on the VLAN creation form. Enter the desired VLAN IDs and/or ID ranges as a comma-separated list (e.g. `100,200-210,4000-4010`). The string `{vid}` may be embedded in the name field as a placeholder for each VLAN's ID; for example, `VLAN-{vid}` yields `VLAN-100`, `VLAN-200`, and so on. All other attributes (status, role, tenant, etc.) are applied to every new VLAN.

The operation is atomic: if any VLAN fails validation (for example, a VLAN ID falling outside the assigned group's permitted ranges), no VLANs are created.

## 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

!!! warning "Site assignment is deprecated"
    The assignment of individual VLANs directly to a site has been deprecated. This ability will be removed in a future NetBox release. Users are strongly encouraged to utilize VLAN groups, which have the added benefit of supporting the assignment of a VLAN to multiple sites.

The [VLAN group](./vlangroup.md) or [site](../dcim/site.md) to which the VLAN is assigned.

### Q-in-Q Role

For VLANs which comprise a Q-in-Q/IEEE 802.1ad topology, this field indicates whether the VLAN is treated as a service or customer VLAN.

### Q-in-Q Service VLAN

The designated parent service VLAN for a Q-in-Q customer VLAN. This may be set only for Q-in-Q custom VLANs.
