Cisco DNA Northbound APIs are characterized by their ability to enable automation of network infrastructure based on intent. These APIs provide a policy-based abstraction of business intent, allowing network administrators to focus on desired outcomes rather than the individual steps involved in achieving those outcomes. This simplifies the management and operation of the network by automating complex processes based on the defined business policies and intents.
