“In order for the MIB to serve the needs of a network-management system, it must meet two objectives: 1. The object or objects used to represent a particular resource must be the same at each node. […] 2. A common scheme for representation must be used to support interoperability.” – William Stallings, op. cit. below In both Internet and OSI network management these two objectives are met by a common structure of managment information (SMI) which is defined in RFC 1155. The SMI is the specification for the tree of MIB objects which which provides a means of associating a common numerical identification code for a given object. The top of the SMI tree is the familiar mapping: iso = 1 org = 3 dod = 6 internet = 1 mgmt = 2 mib-2 = 1 which is the global root prefix of every SNMP MIB object.
