NAS Clients

The NAS Clients Screen displays all configured NAS Clients and is used to create, edit, and delete NAS Clients. NAS acts as a gateway to guard access to a network resource. A client connects to the NAS, and the NAS then connects to a AAA Server to determine whether or not the client’s supplied credentials are valid. The NAS then allows or denies access to the network resource. The network device in the infrastructure attaching with wired or wireless clients will act as a NAS client, communicating to UPAM which acts as a AAA Server.

To access the NAS Clients screen, click on Network Access > UPAM-NAC > NAC Clients under the “Configure” section of the OmniVista Cirrus Menu.
