Management Information Base (MIB)
The MIB, the SNMP-defined data structure, is a tree of standard branches that lead to optional,
non-standard positions in the data hierarchy. The MIB contains both
objects that SNMP is allowed to control (bandwidth allocation or access, for example)
objects that SNMP is allowed to monitor (packet transfer, bit rate, and error data, for example).
The path to each object in the MIB is unique to the object. The endpoint of the path is the object
identifier.
Cascading Path to the MIB
The standard MIB hierarchy includes the following cascading branch structures:
the top (standard body) level:
o ccitt (0)
o iso (1)
o iso-ccitt (2)
under iso (1) above:
o standard (0)
o registration-authority (1)
o member-body (2)
o identified-organization (3)
under identified-organization (3) above:
o dod (6)
o other branches
under dod (6) above:
o internet (1)
o other branches
under internet (1) above:
o mgmt (2)
o private (4)
o other branches
under mgmt (2) above: mib-2 (1) and other branches. (See MIB-II below.)
under private (4) above: enterprise (1) and other branches. (See Canopy Enterprise MIB below.)
Beneath this level are non-standard branches that the enterprise may define.
