Exporters

Exporters extract specific configuration domains from devices. Each produces a clean YAML file.

Vendor Notes

netmodel uses OpenConfig paths, but vendor support varies:

*Arista marks some OSPF interface state as not-supported in their OpenConfig deviations.

Tips

• Export all features first, then filter with --features as needed
• Check metadata.yaml for export timestamp and version
• Empty sections are omitted from output
• Use --no-split for a single YAML file per device
