MIB Structure, Object Identifiers, and MIB Types
As stated previously, the MIB module is a "data map" or collection of management
data objects, which is used by the management station to structure management
requests. These requests return data variables about the status of the specific
device characteristic that was queried. The SNMP protocol facilitates those requests.
There are three types of MIB modules used to collect management data: standard,
experimental, and enterprise. Regardless of the MIB type, all are constructed using
the same hierarchical structure. Additionally, each uses the same basic hierarchy
and global identification mechanism.
The MIB module uses an inverted tree hierarchy to organize the MIB and its objects.
Figure 11.2 provides a simple view of the MIB hierarchy.
