In a dynamic MIB, groups of objects are typically managed using tables. A table in a MIB is a collection of related objects that can be manipulated as a unit. Each row in the table represents an instance of the object, and each column represents a different attribute of the object. The MIB manager can add, delete, modify, or query entries in the table using SNMP commands.
The entries in the table are typically identified by an index, which is a unique identifier for each instance of the object. The index can be a single value or a combination of values that uniquely identify each instance.
The MIB manager can also define new tables or modify existing tables as needed. This allows for flexibility in managing the objects in the MIB and allows for new objects to be added over time as needed.
