Pertemuan 06
Model Informasi - MIB
1
Learning Outcomes
Pada akhir pertemuan ini, diharapkan mahasiswa
akan mampu :
• Menjelaskan Management Information Base
2
Outline Materi
• MIB
3
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
4
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
5
Management Data Base
MDB
Manager
MIB
Managed objects
• 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
6
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
