Assurance provides a comprehensive solution to assure better and consistent service levels to meet growing business demands. It addresses
not just the reactive network monitoring and troubleshooting, but also the proactive and predictive aspects of running a network
and ensuring optimal client, application, and service performance.
Assurance provides the following benefits:
Provides actionable insights into network, client, and application related issues. These issues consist of basic and advanced
correlation of multiple pieces of information, thus eliminating white noise and false positives.
Provides both system-guided as well as self-guided troubleshooting. For a large number of issues, Assurance provides a system-guided approach, where multiple Key Performance Indicators (KPIs) are correlated, and the results from
tests and sensors are used to determine the root cause of a problem, after which possible actions are provided to resolve
the problem. The focus is on highlighting the issue rather than monitoring data. Quite frequently, Assurance performs the work of a Level 3 support engineer.
Provides in-depth health scores for a network and its devices, clients, applications, and services. Client experience is assured
both for access (onboarding) and connectivity.
Companies deal with an abundance of network data. Tackling the volume, variety, speed, and accuracy of network data is crucial
for IT organizations. Assurance is designed to handle network data issues, if any.
Assurance is a multipurpose, real-time, network data collection and analytics engine that can significantly increase the business potential
of network data.
Assurance simplifies and abstracts the collection and analysis layers and offers a rich set of APIs along with a web interface. By
using a single set of network data, Assurance powers a broad set of use cases. These advantages streamline the operational and network management overhead of collecting
and analyzing network data, thereby allowing companies to effectively focus on their business goals.
Given its flexible architecture, Assurance addresses many common use cases, including monitoring and troubleshooting, cost management, and policy discovery, while supporting
the broader Cisco DNA strategy.
The following figure and the information that follows describes the Assurance architecture:
Data Collection and Ingestion: Assurance leverages streaming technologies to collect a variety of network telemetry and contextual data in real time.
Data Correlation and Analysis: As and when data is ingested, Assurance correlates and analyzes the data.
Data Visualization and Action: Data is stored in databases and exposed through APIs to Assurance as well as other applications, such as Capacity Planning. Assurance is an open system that provides the following:
You should continuously use Cisco DNA Center to remain logged in. If you are inactive for too long, Cisco DNA Center logs you out of your session automatically.
Enter an address in your web browser's address bar in the following format. Here, server-ip is the IP address (or the hostname) of the server on which you have installed Cisco DNA Center:
Depending on your network configuration, you might have to update your browser to trust the Cisco DNA Center server security certificate. Doing so will help ensure the security of the connection between your client and Cisco DNA Center.

Log In for the First Time as a Network Administrator
If your user ID has the NETWORK-ADMIN-ROLE assigned, and no other user with the same role has logged in before, you will be
redirected to the Get Started wizard.
The wizard is a quick way to get immediate value from Cisco DNA Center. It consists of a few screens that collect information needed to discover and monitor the condition of your network devices,
and then help you visualize your network's overall health using the Cisco DNA Center home page dashboard.
You can perform all of the same tasks the wizard does using other Cisco DNA Center features. Using the wizard does not prevent you from using those features. You can choose to skip the wizard entirely at
any point and it will not be shown again for you. However, Cisco DNA Center will continue to display the wizard at login to any user with the same role until one such user completes the wizard steps.
After that, Cisco DNA Center never displays the wizard again.
If you skipped the Get Started wizard, you can always revisit it from the Get Started link at the top right of the home page.
Before you begin
You need to have the following information to complete the wizard:
The IP addresses of your SYSLOG and SNMP servers
The IP address and port of your Netflow server
