Names

Names are used to identify managed objects, and are hierarchical in nature. An object
identifier is a globally unique, authoritatively assigned sequence of non-negative integers
which traverse the MIB tree from the root to the node containing the object.

Object identifiers may be represented in one of the following forms:

■

Dotted notation lists the integer values found by traversing the tree from the root to
the node in question, separated by dots. For example, the following identifies the
MIB-II sub-tree:

1.3.6.1.2.1

The following identifies the sysDescr object in the system group of MIB-II:

1.3.6.1.2.1.1.1

■

Textual notation lists the textual descriptions found by traversing the tree from the
root to the node in question, separated by spaces and enclosed in braces. For
following example identifies the internet sub-tree:

{ iso org dod 1}

The name may be abbreviated to a relative form. The following example identifies the
first (directory) node of the internet sub-tree:

{ internet 1}

■

Combined notation lists both the integer values and textual descriptions found by
traversing the tree from the root to the node in question. The integer value is placed
in parentheses after the textual description. The labels are separated by spaces and
enclosed in braces. For example, the following identifies the first (directory) node in
the internet sub-tree:

{iso(1) org(3) dod(6) internet(1) 1}

The name may be abbreviated to the following:

directory(1)

Since there is no effective limit to the magnitude of non-negative integers, and no
effective limit to the depth of the tree, the MIB provides an unlimited name space.

An object is also usually assigned an object descriptor. The object descriptor is a unique,
mnemonic, printable string intended for humans to use when discussing the MIB.
