Here are some commonly asked questions and answers to help with your adoption of Cisco DNA Center Wireless. Subscribe(how-to) to this post to stay up-to-date with the latest Q&A and recommended Ask the Experts (ATXs) sessions to attend.
Q. How does the Cisco DNA Center Assurance work?
A. Cisco DNA Assurance resides within Cisco DNA Center, where it collects streaming telemetry from endpoints, devices, users, and applications across every part of your network. It then uses Cisco AI Network Analytics to define what levels of performance are required for optimal user experience on your network and derive insights on optimization options. These insights are compared with your network policies in the Automation section of Cisco DNA Center to help ensure that the network operation is aligned with business intent. The results are delivered on uncluttered client and device health dashboards, where you can drill down for more detail on any section: clients, services, applications, wired devices, and wireless devices. Issues that require attention are flagged, and you can click on them for suggested issue remediation. Specialized tabs within the Assurance dashboard help with more complex issues:
Device 360/client 360: View device or client connectivity from any angle or context. Included are information on topology, throughput, and latency from different times and different applications
Network time travel: Go back in time and see the cause of a network issue, instead of trying to re-create the issue in a lab
Application experience: Provide unparalleled visibility and performance control on the applications that are critical to your core business, on a per-user basis. Allow users the performance they need on the applications key to their company role
Wi-Fi 6 readiness: Visualize the actual status of your wireless network and which users and endpoints are struggling. Locate areas where it makes sense to upgrade your network and where you can wait Cisco DNA Assurance allows you to grow your network with maximum performance and uncompromising reliability without having to grow your IT budget.
Q. What are the benefits of Cisco AI Network Analytics?
A. Cisco AI Network Analytics provides the following benefits:
More Visibility: Each network is unique, and the network environment is always changing. Cisco AI Network Analytics continuously collects the relevant data from the local networks, correlates the data against the aggregate de-identified data set, and then leverages sophisticated machine learning models to create baselines that are relevant to specific networks and sites. These baselines learn and adapt as the network environments change and as the number of devices, users, and applications evolve.
Greater Insight: Cisco AI Network Analytics uses machine learning to correlate the immense amount of data that is coming from the network against the individualized network baselines, to uncover the issues that can have the greatest impact on the network. This improves issue relevancy. Cisco AI Network Analytics discovers trends and patterns in the network behavior, so that IT can identify issues before they become a problem.
Guided Action: Cisco AI Network Analytics uses machine learning algorithms and automated workflows to perform logical troubleshooting steps, which enable an engineer to execute and resolve the issue. This helps IT detect issues and vulnerabilities, analyze the root causes, and quickly execute corrective actions.
Q. What does Cisco DNA Spaces Act offer and how can customers buy it?
A. Cisco DNA Spaces Act leverages digitization toolkits to act on insights into user and asset behaviour in the network. It translates the network view of people and assets into business view. Cisco DNA Spaces Act triggers contextual notifications and workflows based on the behavior of people and assets. Customers can purchase Cisco DNA Spaces Act as an add-on license for a separate price with Cisco DNA Premier.
Q. What is new with the Cisco DNA Center 2.2.3 version for Wireless?
A. Wireless coverage issues can be challenging to identify and locate. Currently wireless maps do not give a true representation of Wi-Fi signal propagation through actual obstacles, building materials and architectural designs. A new way to visualize your Wi-Fi network is the Wireless 3D analyzer, available in the Cisco DNA Advantage tier. Cisco DNA Center now includes a ground-breaking wireless 3D analyzer which considers granular analysis of millions of spatial RF data points and provides the ability to automatically visualize, identify, locate and alert visualize RF characteristics. Watch a short demo to learn more.
We’ve also improved our Cisco AI Network Analytics offer. New baseline analytics features allow customer to zoom in problematic sites and identify access points that causes Wi-Fi onboarding issues.
Improve your wireless networking by using Ekahau’s wireless planning tools to determine the positioning of your access points to get the best coverage. Using Ekahau tools integration into the Cisco DNA Center make wireless management easier than ever before and streamlining the design process for additional time savings.

Q. How does the Cisco AI Endpoint Analytics receive telemetry data?
A. Cisco AI Endpoint Analytics receives telemetry data in the following ways.
Deep Packet Inspection
Deep packet inspection is an advanced method of packet analysis that is carried out by Cisco Catalyst 9000 Series access devices. These access devices run NBAR, which inspects application traffic and performs protocol analysis to discover, identify, and profile endpoints with high fidelity.
Deep packet inspection profiling is based on various attributes that are collected from endpoint traffic to the network. These attributes are collected across multiple protocols, from packet header layers 4 to 7.
Configuration Management Database Connection
Cisco AI Endpoint Analytics receives endpoint data from your Configuration Management Database Connection (CMDB) for greater accuracy in endpoint profiling. The connection with ServiceNow enables you to receive information from the CMDB to Cisco AI Endpoint Analytics.
Machine Learning Capabilities
Data collected for profiling is anonymized and sent to a Cisco cloud location that serves as a device data lake. Here, machine learning algorithms analyze the data available to create profiling rules that you can evaluate and apply, as needed. Smart profiling rules are suggested through Cisco AI Endpoint Analytics to help make endpoint profiling and management simpler and more efficient for you. Existing rules too are evaluated and improvement suggestions provided based on this continuous learning.
