 ## Interfaces
 
-Interfaces in NetBox represent network interfaces used to exchange data with connected devices. On modern networks, these are most commonly Ethernet, but other types are supported as well. Each interface must be assigned a type, and may optionally be assigned a MAC address, MTU, and IEEE 802.1Q mode (tagged or access). Each interface can also be enabled or disabled, and optionally designated as management-only (for out-of-band management).

Each interface can also be enabled or disabled, and optionally designated as management-only (for out-of-band management). Additionally, each interface may optionally be assigned to a VRF.
 
 !!! note
     Although devices and virtual machines both can have interfaces, a separate model is used for each. Thus, device interfaces have some properties that are not present on virtual machine interfaces and vice versa.
