4.7.7 MIBS
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.
Paths
The standard MIB hierarchy includes the following cascading branch structures:
• the top (standard body) level:
− ccitt (0)
− iso (1)
− iso-ccitt (2)
• under iso (1) above:
− standard (0)
− registration-authority (1)
− member-body (2)
− identified-organization (3)
• under identified-organization (3) above:
− dod (6)
− other branches
• under dod (6) above:
− internet (1)
− other branches
• under internet (1) above:
− mgmt (2)
− private (4)
− 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.
Thus, the path to an object that is managed under MIB-II begins with the decimal string 1.3.6.1.2.1
and ends with the object identifier and instance(s), and the path to an object that is managed under
the Canopy Enterprise MIB begins with 1.3.6.1.4.1, and ends with the object identifier and
instance(s).
