1. The SNMPv2 Network Management Framework
The SNMPv2 Network Management Framework presently consists of three
major components. They are:
o the SMI, described in RFC 1902 [1] - the mechanisms used for
describing and naming objects for the purpose of management.
o the MIB-II, STD 17, RFC 1213 [2] - the core set of managed
objects for the Internet suite of protocols.
o the protocol, STD 15, RFC 1157 [3] and/or RFC 1905 [4], -
the protocol for accessing managed objects.
The Framework permits new objects to be defined for the purpose of
experimentation and evaluation.
2. Object Definitions
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. Objects in the MIB are
defined using the subset of Abstract Syntax Notation One (ASN.1)
