Introduction
According to Colomo-Palacios (2013), a management information base is a database used to administer the entities within a communication network. In most cases, management information base is related to Simple Network Management Protocol. Management information base uses both SNMP and TCP/IP protocol stack to query agents of simple network management protocol in every network device. Saad, Rosenthal-Sabroux, & Gargouri (2014) contend that SNMP exists in three versions including SNMPv1, SNMPv2 and SNMPv3. The first version of SMMP is widely used as compared to the other versions since it’s the easiest to use. While the first version of the protocol is easier to use, the second version presented expanded data types, more affluent error handling and enhanced effectiveness in retrieving information (Colomo-Palacios, 2013). The third version of simple network management protocol presents both enhanced administrative features and commercial-grade security. Management information base exists in four types. Management information base works hand in hand with NMS. Each NMS have access to management information base agent it administers. MIB data structures are used to store values and instances of device objects used by NMS.
The components of management information base include physical configuration information, historical information and logical configuration information (Colomo-Palacios, 2013). Physical configuration information is made up of the serial numbers, the MAC addresses, the physical setting of interface line cards and interface ports and device types (Saad, Rosenthal-Sabroux, & Gargouri, 2014). On the other hand, logical configuration information includes configured logical resources on the device and the parameters settings like telephone numbers, IP addresses and logical interfaces. Similarly, historical information entails logs for different types of events and snapshots of state information related to performance like packet counts and firewall logs.
