!!! info "This feature was introduced in NetBox v4.2."
A virtual circuit can connect two or more interfaces atop a set of decoupled physical connections. For example, it's very common to form a virtual connection between two virtual interfaces, each of which is bound to a physical interface on its respective device and physically connected to a provider network via an independent physical circuit.
The provider network across which the virtual circuit is formed.
The provider account with which the virtual circuit is associated (if any).
The unique identifier assigned to the virtual circuit by its provider.
The assigned virtual circuit type.
The operational status of the virtual circuit. By default, the following statuses are available:
| Name |
|---|
| Planned |
| Provisioning |
| Active |
| Offline |
| Deprovisioning |
| Decommissioned |
!!! tip "Custom circuit statuses"
Additional circuit statuses may be defined by setting `Circuit.status` under the [`FIELD_CHOICES`](../../configuration/data-validation.md#field_choices) configuration parameter.
