About Clients

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.

Monitor and Troubleshoot the Health of All Client Devices

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.
Use this procedure to get a global view of the health of all wired and wireless clients and to determine if there are potential issues that must be addressed.
Assurance uses machine learning algorithms to extract behavioral patterns in the network and predict trends.
These trends are displayed as baselines in the Client Onboarding Time and Client Count Per SSID dashlets.

Note
The client health data might take up to an hour to populate if an HA failover has occurred.
Before you begin
Configure Assurance. See Basic Setup Workflow.

Step 1
Click the menu icon ( ) and choose Assurance > Health.
The Overall health dashboard appears.
Step 2

Understand Client Health Score and KPI Metrics

This section provides information about how the client health scores and KPI metrics are computed.

Client Health Score
The Client Health score (Wireless or Wired) is the percentage of the number of healthy client devices (a health score from 8 to 10) in a target category, divided by the total number of client devices in that category. The score is calculated every 5 minutes.
For example: 90% (health score) = 90 (client devices in a target category with health score from 8 to 10) ÷ 100 (total number of client devices in that category)
The Individual Client Health score is the sum of the Client Onboarding score and the Client Connectivity score. The client health score ranges from 1 to 10, with a score of 0 for inactive clients. It is calculated as follows:
Wired Client: Link to first switch is up, authentication and authorization is successful and IP address is received. Client score is 10.
Wireless Client: Client joined the network and has good connection in terms of the RSSI and SNR KPIs.

Client Onboarding Score
The Client Onboarding score indicates the experience of a client device while connecting to the network.

  • If a client connects to the network successfully, the score is 4.
  • If a client failed to connect to the network, the score is 1.
  • If a client is idle, the score is 0.

The Client Onboarding score is calculated as follows:
Wired Client: Link to the first switch is up, authentication and authorization is successful, and IP address received.
Wireless Client: Client Onboarding score range is from 1 to 4. When the client connects to the network
successfully, the score is 4. If the client failed to connect to the network, the score is 1.

Client Connectivity Score
The Client Connectivity score indicates the experience of the client device after the device is connected to the network. The score is calculated as follows:
Wired Client: Connectivity score can be 2 or 6. Link errors determine the Connectivity score and the resulting Overall Health score, as shown below:

  • If a client onboards successfully but has link errors, the Connectivity score is 2 and the Overall Health score is 6.
  • If the client onboards successfully and there are no link errors between the client and the first-hop switch, the Connectivity score is 6 and the Overall Health score is 10.

Wireless Client: Connectivity score can be 0, 4, or 10. The RSSI and SNR range determines the Connectivity score and the resulting Overall Health score is calculated as the weighted average of the RSSI-driven Connectivity score and the SNR-driven Connectivity score.
