Cisco DNA Center explained |Digital Network Architecture| Intent-based networking |Free CCNA 200-301
Cisco DNA also known as Cisco Digital Network Architecture (Cisco DNA) is Cisco’s architecture for enterprise networks
It provides an open, extensible, and software-driven approach that makes the network simpler to manage and more agile and responsive to business needs.
Cisco DNA is an intelligent system that encompasses policy, automation, analytics, and open platform capabilities to deliver on all required aspects of an intent-based network.
In case if you do not know what IBN is.
Intent-based networking (IBN) is a form of network administration that incorporates artificial intelligence (AI), network orchestration and machine learning (ML) to automate administrative tasks across a network.
The goal of IBN is to reduce the complexity of creating, managing and enforcing network policies and reduce the manual labor associated with traditional configuration management.
Cisco DNA is your team’s bridge to an intent-based network.
Cisco DNA Center is a powerful network controller and management dashboard that lets you take charge of your network,
Cisco DNA Center is at the heart of the Cisco Digital Network Architecture and is the only centralized intent-based network management system to bring all this functionality into an integrated controller and present it through a single pane of glass.
Cisco DNA Center has two notable roles:
* ♣ As the controller in a network that uses Cisco SDA
* SDA and DNA Center go together, work closely together, and any serious use of SDA requires the use of DNA Center.
* ♣ As a network management platform for traditional (non-SDA) network devices, with an expectation that one day DNA Center may become Cisco’s primary enterprise network management platform
Cisco DNA Center exists as a software application that Cisco delivers pre-installed on a Cisco DNA Center appliance
The software follows the same general controller architecture as shown in the fig
Cisco DNA Center includes a robust northbound REST API along with a series of south- bound APIs. For most of us, the northbound API matters most, because as the user of SDA networks, you interact with SDA using Cisco DNA Center’s northbound REST API or the GUI interface.
Cisco DNA Center supports several southbound APIs so that the controller can communicate with the devices it manages.
You can think of these as two categories:
* ♣ Protocols to support traditional networking devices/software versions: Telnet, SSH, SNMP
* ♣ Protocols to support more recent networking devices/software versions: NETCONF, RESTCONF
Use fo Cisco DNA Center enables you to do
Automate:
Allows Configuration and provisioning of thousands of network devices across your enterprise in minutes, not hours.
Automation reduces manual operations and the costs associated with human errors, resulting in more uptime and improved security.
Secure policy:-
Based on business needs you can deploy group-based secure access and network segmentation
With Cisco DNA Center, you apply policy to users and applications instead of to your network devices.
Assurance:-
Cisco DNA Center uses your network’s wired and wireless devices to create sensors everywhere, providing real-time feedback based on actual network conditions.
With a quick check of the health scores on the Cisco DNA Center dashboard, you can see where there is a performance issue and identify the most likely cause in minutes.
Extend ecosystem:
With the new Cisco DNA Center platform, IT can now integrate Cisco solutions and third-party technologies into a single network operation .
Cisco DNA Center allows you to run the network with open interfaces.
