# Agent Less Telemetry

## Network Device Configuration Interfaces

### Cumulus (NVUE API)

Cumulus Networks offers the NVUE (Network Virtualization Utility Engine) API, providing an abstraction layer over traditional configuration mechanisms. This allows for a more intuitive and standardized approach to network configuration and management, echoing modern software development practices.

### Arista EOS (OpenConfig)

Arista's EOS platform leverages OpenConfig, a collaborative effort among network operators to define vendor-neutral data models for configuring and managing networks. OpenConfig facilitates simplified, consistent interactions across different network devices.

### Cisco NX-OS (gRPC)

Cisco's NX-OS supports gRPC, enabling efficient, scalable, and programmatic network device management. This interface allows for the streaming of telemetry data and the execution of configuration commands.
