Right, SNMP is the Internet Standard Management Framework. Yet we've had RADIUS/DIAMETER alongside SNMP for decades then others come up from time to time COPS-PR. So while we've had one primary protocol IETF has others. Today I don't think it likely we're ever going back to one. Multiple mgmt frameworks I think is a result of the nature of problem first documented in Bellcore M.3010 breaking down operational practices into FCAPS. That the IETF now has more than one mgmt technology is imo a good thing. But like you said it now takes a conversation to answer the question. If often explain the role of SNMP in appliances to others who might prefer to use one web service api for all of FCAPS this way: In as much as I don't drive moving van to work opting for a small commuter car, I find that I do need to pick and choose among mgmt protocols appropriately. No one size fits all or plugs into the operational environment of most operators w/o needing some new adapter. So for instance if I want to monitor my network, its gonna be SNMP hands down. All the gear I have and will buy has it. Cost to develop cost to deploy known/cheap. Sure one can argue that IPFIX might do it better but it is not better enough such that the cost would make any sense to business to absorb such cost. And just as I'd use IPFIX for flow accounting or use NETCONF for configuration, that's just what is gonna look like. No short cuts or easy asnwers. My hope is that when IETF comes up with new protocols they build a decent data model to monitor it and a data model to configure it and whatever other model that makes sense and whatever else. The monitoring data model doesn't have to be SMIv2 but should be generated such that we get IETF standard oids. Then when it comes time for me to build a product that uses IETF technology I am lucky to stand on the shoulders of giants and use high quality MIB modules, example NTPv4-MIB, IP-MIB, not only in an SNMP agent but also in the proprietary protocols. Then sometimes I'm not so lucky as in no SYSLOG-MIB and NFS mib modules.
