Pertemuan 06 Model Informasi - MIB

2. Learning Outcomes Pada akhir pertemuan ini, diharapkan mahasiswa
akan mampu :
Menjelaskan Management Information Base

3. Outline Materi
MIB

4. Management Information Base
Information base contains information about objects
Organized by grouping of related objects
Defines relationship between objects
It is NOT a physical database. It is a virtual database that is compiled into management module

5. MIB View and Access
A managed object has many attributes – its information base
There are several operations that can be performed on the objects
A user (manager) can view and perform only certain operations on the object by invoking the management agent
The view of the object attributes that the agent perceives is the MIB view
The operation that a user can perform is the MIB access

6. Management Data Base Distinction between MDB and MIB
Manager
Managed objects
MDB
MIB
Distinction between MDB and MIB
MDB physical database; e.g.. Oracle, Sybase
MIB virtual database; schema compiled into management software
An NMS can automatically discover a managed object, such as a hub, when added to the network
The NMS can identify the new object as hub only after the MIB schema of the hub is compiled into NMS software

MIB-II (RFC 1213) is superset of MIB-I RFC 1213 defines eleven groups; expanded later
Objects that are related grouped into object groups
