Outline Materi MIB

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

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

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
