ADTRAN Calix This document defines a flexible modular alternative YANG model for bulk data collection and export via the IPFIX protocol to the model defined in [RFC6728] "Configuration Data Model for the IP Flow Information Export (IPFIX) and Packet Sampling (PSAMP) Protocols". The model defined in this RFC configures the IPFIX exporter and collector (if applicable) and refers to the bulk data monitoring configuration. Optionally, the model can be configured to support PSAMP export of data via IPFIX. This document obsoletes [RFC6728] (if approved).
