When this feature is enabled, responses to gNMI subscribe requests contain the default values for YANG leafs if those leafs do not have any other value.

When this feature is enabled, responses to gNMI get requests as well as NETCONF get-config responses will contain the default values for YANG leafs if those leafs do not have any other value. This means that where a leaf value would normally be returned in a response, its default value (as defined in the YANG model) will be returned if the leaf does not have any other value assigned to it. Before this change, leafs that had a default value would not have been included in gNMI get responses.

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.
