Explanation
The overall health page of the assurance component in the Cisco DNA Center displays two primary categories: Client and Network1. The Client category shows the health score of all the wired and wireless clients connected to the network, along with the number of clients, the top issues affecting the clients, and the distribution of clients by type, OS, and SSID1. The Network category shows the health score of all the network devices, such as switches, routers, wireless controllers, and access points, along with the number of devices, the top issues affecting the devices, and the distribution of devices by site, family, and role1.
The other options are not primary categories on the overall health page. Server is not a category, but a type of client that can be filtered in the Client category1. Access-Distribution and Core are not categories, but roles of network devices that can be filtered in the Network category1. Wired is not a category, but a subcategory of the Client category that shows the health score of the wired clients only1.
