It is gone finally… [macOS Server 5.4 changes in High Sierra you need to know about!])https://www.imore.com/changes-macos-server-54-high-sierra)
File Transfer Protocol (FTP): A longtime a security risk, for example for sending password information in clear text, FTP support will be removed from macOS server if you upgrade.
As my xeros printer/scanner suppors only ftp or samba(which is much much slower than the ftp) I have to run my own ftp server in my mac mini.

Summary JSON, “compact” GPB and “Key-Value” GPB
“Compact” GPB data on wire can be decoded without the decoder ring while “Key-Value” GPB data is Self-Describing. Compact GPB can be used with UDP(default) and TCP(optionally) “Key-value” GPB is only for TCP 833 bytes of compact GPB while more than 4000 bytes for Key-value GPB Compressed JSON(?)
Seems that configuration and operation data are defined in a different yang file though it is not clear they are module or submodule
The models are in the .yang format. A model with: -oper in the model name indicates an operational model. For example, Cisco-IOS-XR-cdp-oper.yang is an operational model for Cisco Discovery Protocol (CDP). -cfg indicates a configuration model. For example, Cisco-IOS-XR-cdp-cfg.yang is a configuration model for CDP. -act indicates a NETCONF actions model.

Summary Periodic polling -> Pushing(Streaming) Model based data with YANG Use standard encoding such as JSON, Google Protocol Buffers Easy to manipulate, connect to analytic solutions 1-min poll is too slow For the last 25 years, network operators have heavily relied on SNMP polling and CLI screen-scraping to extract operational data from the network. But the new and automated demands of today’s networks have pushed these mechanisms to the breaking point.
