How would you describe Structure of Management Information (SMI)? Also justify, how it is useful for a managed object?

Answer:

It is a framework that explains the basic type of information that is being manipulated by SNMP. The skeleton is being provided by the data in which the data for basic format and management of data hierarchy is provided but the objects that can be managed are described. From which these objects are developed that building blocks are provided in this system. To make sure that object identifiers are unique, each company is accountable for a unique section of the OID tree. Just as ISO and CCITT have accountability for their portions, the Internet Activities Board (IAB) has duty for the internet portion. To enable companies to assist objects that may also not be described in the widespread MIB, the IAB reserves a element of the OID tree for organizations MIBs. This gives vendors with the flexibility they need. The SMI defines fundamental statistics types that make it handy to describe managed objects. These sorts are: Integer, Octet_String, Object_Identifier, ipAddress, Counter, Gauge, TimeTicks, NetworkAddress, and Opaque. Readers who are involved in the precise semantics of these objects are stimulated to study the RFC for further information.
