SNMP v3

Simple Network Management Protocol Version 3 (SNMP v3) is defined by RFC 3411–RFC 3418. It has primarily added security and remote configuration enhancements to SNMP. As of 2004, the Internet Engineering Task Force (IETF) recognizes SNMP v3 as the de facto standard version of SNMP. The IETF deemed it a full Internet standard, the highest maturity level for an RFC, and consider all previous versions of SNMP to be obsolete. The IETF cut them off like Michael Corleone said to his brother, “...you’re nothing to me now. You’re not a brother; you’re not a friend. I don’t want to know you or what you do....”

SNMP v3 is derived from, and builds upon, the original SNMP and SNMP v2. All versions share the same basic structure and components: managed nodes, an agent (software that runs on managed devices), and a network management system (NMS) (software that runs on the manager).
