gNPSI is an OpenConfig protocol designed to act as a proxy between the sFlow agent and interested gRPC clients. The gNPSI server receives datagrams from sFlow, repackages the datagrams in the protobuf message format and forwards these messages onto any subscribed gRPC clients. The protobuf used for this feature is available at the link above.

enrollz/attestz defines a set of gRPC-based services for TPM enrollment and attestation of network devices. Enrollz: provides the capability to verify the switch’s TPM-rooted identities and rotate switch owner certificates on the device. Attestz: provides the capability to attest the device by inspecting the contents of the different PCR ensuring no malicious tampering.

This feature allows Octa to act as a collector for IPFIX and sFlow datagrams and to aggregate and stream the collected data in response to a gNMI subscription. Octa is a process in EOS which combines OpenConfig and certain TerminAttr functionality, primarily with the intent of servicing gNMI requests for OpenConfig paths and for "EOS native" paths.
