forwarded to the VLANs where hosts have requested it/them (Wikipedia).

NAS
NAS is an acronym for Network Access Server. The NAS is meant to act as a gateway to guard
access to a protected source. A client connects to the NAS, and the NAS connects to another
resource asking whether the client's supplied credentials are valid. Based on the answer, the
NAS then allows or disallows access to the protected resource. An example of a NAS
implementation is IEEE 802.1X.
