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).

Objects

An object in the MIB can have either only a single instance or multiple instances, as follows:

• a scalar object has only a single instance. A reference to this instance is designated by

.0, following the object identifier.

• a tabular object has multiple instances that are related to each other. Tables in the MIB

associate these instances. References to these instances typically are designated by

.1, .2, and so forth, following the object identifier.
