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.
The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

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.

Use the Timeline Slider to view the healthy client percentage for a more granular time range. Hover your cursor within the timeline to view the wireless and wired client health score percentage at a specific time. You can click and drag the timeline boundary lines to specify the time range. This sets the context for client data that is displayed in the dashboard dashlets. You can use the arrow buttons on the right of the timeline to view data for up to 30 days. The dotted horizontal line represents the threshold value for healthy clients, which by default is set to 40%. To change the threshold value:

Step 7 |
View the individual client health score in the Client Details area, below the timeline. The individual client health score is an aggregate of the client's onboarding status, RSSI, and SNR. If you search by the user ID, the Individual Client Health score that is displayed is the minimum score of all the monitored client devices associated with that user. For more information, see Individual Client Health Score. If you search by MAC address or IP address, the Individual Client Health score is the health score for that client device. The color of the health score represents its severity. The health is measured on a scale of 1 to 10, with 10 being the best score, and a score of 0 for inactive client devices, where the health data is not applicable:

This section provides information about how the client health scores and KPI metrics are computed.
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.
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 is 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.
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.
RSSI-Driven Connectivity Score | |
---|---|
Client's RSSI | RSSI-Driven Connectivity Score |
If RSSI is less than or equal -72 dBm. |
The client receives a RSSI-driven connectivity score of 4 and is considered to be in fair health. |
If RSSI is greater to -72 dBm. |
The client receives a RSSI-driven connectivity score of 10 and is considered to be in good health. |
SNR-Driven Connectivity Score | |
---|---|
Client's SNR | SNR-Driven Connectivity Score |
If SNR is less than or equal to 9. |
The client receives a SNR-driven connectivity score of 4 and is considered to be in fair health. |
If SNR is greater than 9. |
The client receives a SNR-driven connectivity score of 10 and is considered to be in good health. |
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 RSSI and SNR KPIs.
Client's Onboarding and Connectivity | Resulting Client Health Score |
---|---|
If the client failed onboarding. |
The client receives a health score of 1 and is considered to be in poor health. |
If the client's RSSI and SNR are below threshold. |
The client receives a health score of 4 and is considered to be in fair health. |
If either the client's RSSI or SNR is below threshold. |
The client receives a health score of 7 and is considered to be in fair health. |
If the client's RSSI and SNR is above threshold. |
The client receives a health score of 10 and is considered to be in good health. |
