What are SNMP MIBs?
A Management Information Base (MIB):
Presents a collection of information that is organized hierarchically.
Is accessed by using a network-management protocol, such as SNMP.
References managed objects and object identifiers.
Managed object—A characteristic of a managed device. Managed objects reference one or more object
instances (variables). Two types of managed objects exist:
Scalar objects—Define a single object instance.
Tabular objects—Define multiple-related object instances that are grouped together in MIB tables.
Object identifier (or object ID)—Identifies a managed object in the MIB hierarchy. The MIB hierarchy
is depicted as a tree with a nameless root. The levels of the tree are assigned by different organizations
and vendors.
