You can use Assurance to monitor and troubleshoot the overall health of your enterprise. An enterprise consists of network devices and clients.
A network consists of one or more devices, including routers, switches, wireless controllers, and access points. Note that clients are not a part of the network health score.
A client is an end device (computer, phone, and so on) that is connected to a network device (access point or switch). Cisco DNA Center supports both wired and wireless clients.
