The MIBs for a specific company’s device are called an enterprise MIB. Standards have been made describing the format of common data. These are called standard MIBs. A special set of these MIBs are called MIB-II. These are MIBs for data you would expect every network device to have such as Ethernet, TCP, and UDP.

Answer. A database of an NMS is a physical database containing the network object sand values. It is implemented using any proprietary database software. MIB is a virtual database that is used by network management and agent applications to exchange information about the network objects.
Why do we need MIB?
You need MIB files to be able to read and understand OIDs – that’s how you can monitor the status of a device. MIB files and OIDs are an essential part of the SNMP architecture. These two components are critical pieces that allow you to monitor your remote sites and run SNMP troubleshooting.
What is a MIB file?
How does a MIB file work?
A MIB or Management Information Base is a formatted text file that resides within the SNMP manager designed to collect information and organize it into a hierarchical format. The SNMP manager uses information from the MIB to translate and interpret messages before sending them onwards to the end-user.
