The purpose of this document is to describe coexistence between version 2 of the Internet-standard Network Management Framework, termed the SNMP version 2 framework (SNMPv2) [1], and the original Internet-standard Network Management Framework (SNMPv1), which consists of these three documents:
RFC 1212 [3] which defines a more concise description mechanism, which is wholly consistent with the SMI.
RFC 1157 [4] which defines the Simple Network Management Protocol (SNMP), the protocol used for network access to managed objects.
