What’s the Cisco DNA? What the Cisco DNA can do for you? In today’s digital world and era, we need to talk about the Cisco DNA, Cisco Digital Network Architecture, is an open, programmable architecture that turns business intent into business results.
This open, extensible and software driven architecture accelerates and simplifies your enterprise network operations.
Only Cisco provides a single network fabric that is powered by deep intelligence and integrated security to deliver automation and analytics across your entire organization at scale. Cisco DNA gives IT time back from time-consuming, repetitive network configuration tasks so you can focus on the innovation your business needs.
Cisco DNA automation is built on a Software-Defined Network (SDN) controller, rich contextual analytics, network virtualization and the limitless scalability of the cloud.
Most Cisco routers, switches and wireless systems shipping today support Cisco DNA now or with a software update. And with Cisco ONETM Software, you can continue to protect your investments and benefit from new architecture innovations that can be activated through software.
Traditional network architectures are unable to scale for the digital era. Cisco has reimagined our network architecture with the following characteristics:
- Cloud service management: Design, provision, enable policy and assure network services through centralized management. Enable visibility of end-to-end network services for campus and branch environments, on-premises or in the cloud.
- Automation: Fully automate the network infrastructure based on one policy across the entire access network, acting as a single fabric. Simplify and scale operations by automating day-to-day configuration, provisioning, and troubleshooting.
- Analytics: Proactively predict performance through machine learning to correlate user, device and application data for business and operational insights. Identify issues and provide actionable insight to deliver better, more personalized experiences.
- Security: Detect and mitigate threats with end-to-end network segmentation and enforce security policies across the network. Identify and mitigate threats and vulnerabilities in encrypted traffic with network analytics.
- Virtualization: Deploy network services in minutes on any platform – branch, colocation or public cloud – and connect users to applications with one seamless network.
Cisco has applied these characteristics to Enterprise Networks products and solutions so you can move forward with building an open, extensible and agile network.

2. What Cisco DNA Center enables you to do?
Save time by using a single dashboard to manage and automate your network. Design your enterprise network by starting with geographical locations, creating sites, and then adding network devices. Quickly scale your business with intuitive workflows and reusable templates. Configure and provision thousands of network devices across your enterprise in minutes, not hours.
Automate network changes to respond to business needs quickly. Cisco DNA Center uses real-time feedback from the network data platform, which collects information from network devices. Using deep insights through machine learning and correlation of data sources, Assurance provides insights about network, client, and application performance. These insights lead to recommendations for solving issues and identifying the root cause of problems, as well as predicting utilization based on trends and deviations from a baseline behavior. Basically, Assurance allows you to run the network with maximum performance.
Quickly implement policy across your network to address changing business needs. Deploy group-based secure access and network segmentation based on business needs. With Cisco DNA Center, you apply policy to users and applications instead of to your network devices. Automation reduces manual operations and the costs associated with human errors, resulting in better uptime and improved security. Assurance then assesses the network and uses context to turn data into intelligence, making sure that changes in the network device policy configuration achieve your intent.
Reduce network downtime with real-time network assurance. Use Assurance to deliver a consistent, high-quality application experience. Move from a reactive to a proactive monitoring strategy with Cisco DNA Center. Assurance will determine how the network will perform, predict network problems across your enterprise, and provide recommended solutions to reduce downtime.

6. DNA Analytics and Assurance
DNA Analytics and Assurance offers comprehensive network visibility. It collects data from users, devices, and applications to proactively identify problems. Network analytics and automation help you quickly resolve them, so you can increase availability and deliver a better user experience.
Putting analytics into action
The key to Cisco DNA Analytics and Assurance is its ability to continually collect and put insights into action. Cisco Network Data Platform (NDP) collects next generation streaming telemetry, as well as traditional NetFlow records, Simple Network Management Protocol (SNMP) events, and syslog information in real time to continually monitor how devices, users, and applications are performing. The solution baselines the collected data to establish “norms” and then uses it for network analysis to find outliers.
The solution then performs advanced processing to evaluate and correlate events. You don’t need dedicated data scientists. In fact, we’re able to quickly identify the most likely root cause and offer proven best practices for resolving issues. For more detailed discovery, you can still drill down to the underlying data.
This correlated data is instantly actionable through the Assurance functions within Cisco DNA Center. The analytic insights are fed directly into this single-pane-of-glass dashboard. Inside the dashboard, the insights are aligned to tasks, so the information is available to support the way you work.
Faster troubleshooting, proactive monitoring, and anomaly detection
With a quick check of the health scores, you can see where there is a performance issue and the most likely cause. We even give you remediation options based on 30 years of Cisco expertise. When there are no issues, Cisco DNA Analytics and Assurance continues to evaluate trends within the network to identify areas where there might be performance or capacity degradation in the future. As a result, you can mitigate problems before they affect your network.
The insights you gather from your network devices can influence your automation configuration and deployment decisions. Cisco DNA Center provides an integrated automation and assurance/analytics workflow, enabling you to quickly take action to remediate the issue. Think of it as a closed feedback loop.
