Monitor and Troubleshoot Overall Enterprise Health

About Enterprise

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 and devices in maintenance mode are not 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.
