Software-defined networks (SDNs) are designed to be more flexible and easier to manage compared to traditional infrastructure. They utilize overlay networks to decouple network services from the hardware, allowing for efficient resource utilization and simplified virtual network services provisioning. SDNs are also designed to adapt quickly to changing business needs or traffic patterns, without the need for manual reconfiguration or significant downtime.

When integrating a Grafana dashboard with Cisco DNA Center to receive network events, the integration bundle that is enabled is:

• C: Network Events for REST API Endpoint. This integration allows Grafana to receive network event notifications from Cisco DNA Center. The REST API Endpoint serves as the interface through which Grafana can subscribe to and receive network events, which can then be visualized on the dashboard1.

The difference between OpenConfig and native YANG data models lies in their development and purpose:

• D: Native models are developed by vendors and are specific to their platforms. They are designed to integrate features or configurations that are relevant only to that vendor’s platform. Native models, being vendor-specific, provide the most detailed and granular control over the vendor’s devices1.

OpenConfig models, on the other hand, are developed by a collaborative group of network operators and are intended to be vendor-neutral. They aim to provide a more standardized model that can be used across different vendors’ equipment, focusing on the needs of the operators rather than the specific capabilities of the devices1.
