## Frequently asked questions

### What RFC defines SNMP?

It depends on the version. SNMPv1 is defined by RFC 1157. SNMPv2c is defined across RFC 1901, 1905, and 1906. SNMPv3 is defined by the set RFC 3411 through 3418, collectively designated Internet Standard 62 (STD 62). There's no single "SNMP RFC" — the protocol evolved across these documents, with v3 being the current, secure standard.

### What is STD 62?

STD 62 is the IETF's Internet Standard designation for SNMPv3 — the label applied to the set of RFCs 3411 through 3418 that define the version. An STD number signals a full Internet Standard rather than a proposal, marking SNMPv3 as a mature, stable specification. Within STD 62, RFC 3414 defines USM (security) and RFC 3415 defines VACM (access control).

### What RFC is MIB-II?

MIB-II is defined by RFC 1213. It's the foundational standard MIB, providing the base system group (sysDescr, sysName, sysUpTime) and the original interface objects that essentially every SNMP agent implements. The interface objects were later modernized and extended by the IF-MIB (RFC 2863), which added the 64-bit high-capacity counters, but MIB-II remains the common baseline.

### Where do I read SNMP RFCs?

The authoritative source is the IETF datatracker at datatracker.ietf.org, which hosts every RFC with its current status — whether it's a Proposed Standard, an Internet Standard with an STD number, or obsoleted by a newer document. Always check status there: an obsoleted RFC has been replaced, and the datatracker tells you which document supersedes it. Treat it as the ground truth over any secondhand citation.
