Intent-based networking (IBN) lets you describe what you want, not how to achieve it. The system translates your intent into configurations.
Traditional: "Configure ACL on switch A port to block TCP port from subnet "
Intent-based: "Block SSH access from the guest network to servers"
IBN components:
Intent translation. Convert business language to network policies
Automation. Push configurations to all devices
Verification. Confirm network behaves as intended
Assurance. Monitor for drift from intent
