+# Virtual Circuits
+
+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](./providernetwork.md) via an independent [physical circuit](./circuit.md).
+
+## Fields
+
+### Provider Network
+
+The [provider network](./providernetwork.md) across which the virtual circuit is formed.
+
+### Provider Account
+
+The [provider account](./provideraccount.md) with which the virtual circuit is associated (if any).
+
+### Circuit ID
+
+The unique identifier assigned to the virtual circuit by its [provider](./provider.md).
+
+### Status
+
+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.

+# Virtual Circuit Terminations
+
+This model represents the connection of a virtual [interface](../dcim/interface.md) to a [virtual circuit](./virtualcircuit.md).
+
+## Fields
+
+### Virtual Circuit
+
+The [virtual circuit](./virtualcircuit.md) to which the interface is connected.
+
+### Interface
+
+The [interface](../dcim/interface.md) connected to the virtual circuit.
+
+### Role
+
+The functional role of the termination. This depends on the virtual circuit's topology, which is typically either peer-to-peer or hub-and-spoke (multipoint). Valid choices include:
+
+* Peer
+* Hub
+* Spoke

+# MAC Addresses
+
+A MAC address object in NetBox comprises a single Ethernet link layer address, and represents a MAC address as reported by or assigned to a network interface. MAC addresses can be assigned to [device](../dcim/device.md) and [virtual machine](../virtualization/virtualmachine.md) interfaces. A MAC address can be specified as the primary MAC address for a given device or VM interface.
+
+Most interfaces have only a single MAC address, hard-coded at the factory. However, on some devices (particularly virtual interfaces) it is possible to assign additional MAC addresses or change existing ones. For this reason NetBox allows multiple MACAddress objects to be assigned to a single interface.
+
+## Fields
+
+### MAC Address
+
+The 48-bit MAC address, in colon-hexadecimal notation (e.g. `aa:bb:cc:11:22:33`).
