> # Device Alias Features

> Device aliases have the following features:

> - The device alias information is independent of your VSAN configuration.
> - The device alias configuration and distribution is independent of the zone server and the zone server database.
> - You can import legacy zone alias configurations without losing data.
> - The device alias application uses the Cisco Fabric Services (CFS) infrastructure to enable efficient database management and distribution. Device aliases use the coordinated distribution mode and the fabric-wide distribution scope (refer to the Cisco MDS 9000 Family NX-OS System Management Configuration Guide).
> - When you configure zones, IVR zones, or QoS features using device aliases, and if you display these configurations, the device aliases are automatically displayed along with their respective pWWNs.
