Management Information Base (MIB)
7 Management Information Base
(MIB)
The Management Information Base (MIB) is designed in the form of an
abstract tree structure.
The branching points are the object classes. The "leaves" of the MIB are
called generic object classes.
If this is required for unique identification, the generic object classes are
instantiated, i.e. the abstract structure is mapped onto reality, by specifying
the port or the source address.
Values (integers, time ticks, counters or octet strings) are assigned to these
instances; these values can be read and, in some cases, modified. The
object description or object ID (OID) identifies the object class. The
subidentifier (SID) is used to instantiate them.
Example:
The generic object class
hm2PSState (OID = 1.3.6.1.4.1.248.11.11.1.1.1.1.2)
is the description of the abstract information "power supply status". However,
it is not possible to read any information from this, as the system does not
know which power supply is meant.
Specifying the subidentifier (2) maps this abstract information onto reality
(instantiates it), thus indicating the operating status of power supply 2. A
value is assigned to this instance and can then be read. The instance "get
1.3.6.1.4.1.248.11.11.1.1.1.1.2.1" returns the response "1",
which means that the power supply is ready for operation.
