1.2. RFCs and SNMP Versions

The Internet Engineering Task Force(IETF) is responsible for defining the standard protocols that govern Internet traffic, including SNMP. The IETF publishes Requests for Comments(RFCs), which are specifications for many protocols that exist in the IP realm. Documents enter the standards track first as proposed standards, then move to draft status. When a final draft is eventually approved, the RFC is given standard status -- although there are fewer completely approved standards than you might think. Two other standards-track designations, historical and experimental, define (respectively) a document that has been replaced by a newer RFC and a document that is not yet ready to become a standard. The following list includes all the current SNMP versions and the IETF status of each (see Appendix D, "SNMP RFCs" for a full list of the SNMP RFCs):

The official site for RFCs is http://www.ietf.org/rfc.html. One of the biggest problems with RFCs, however, is finding the one you want. It is a little easier to navigate the RFC index at Ohio State University (http://www.cis.ohio-state.edu/services/rfc/index.html ).
