The Internet-standard Network Management Framework consists of three
components. They are:
STD 16/RFC 1155std16 [3] which defines the SMI, the mechanisms used for
describing and naming objects for the purpose of management. STD
16/RFC 1212std16 [13] defines a more concise description mechanism,
which is wholly consistent with the SMI.
RFC 1156hist [4] which defines MIB-I, the core set of managed objects
for the Internet suite of protocols. STD 17/RFC 1213std17 [6] defines
MIB-II, an evolution of MIB-I based on implementation experience
and new operational requirements.
STD 15/RFC 1157hist [5] which defines the SNMP, the protocol used for
network access to managed objects.
The Framework permits new objects to be defined for the purpose of
experimentation and evaluation.
