+ <font face="Arial" size="2"> A management information base (MIB) is
+ used to store the structured information representing network elements
+ and their attributes. The structure itself is defined in a standard
+ called the structure of management information (SMI), which defines
+ the data types that can be used to store an object, how those objects
+ are named, and how they are encoded for transmission over a network.
+ <img border="0" src="../../images/1.gif" align="absmiddle" width="12" height="12"></font><p>
+
+ <font face="Arial" size="2"> MIBs are highly structured depositories
+ for information about a device. Many standard MIBs exist, but more
+ MIBs that are proprietary exist to uniquely manage different vendor’s
+ devices. The original SMI MIB was categorized into eight different
+ groups, totaling 114 managed objects. More groups were added to define
+ MIB-II, which now replaces MIB-I.</font></p>
+ <p>
+
+ <font face="Arial" size="2">All managed objects in the SNMP
+ environment are arranged in a hierarchical or tree structure. The leaf
+ objects of the tree, which are the elements that appear at the bottom
+ of the diagram, are the actual managed objects. Each managed object
+ represents some resource, activity or related information that is to
+ be managed. A unique object identifier, which is a number in dot
+ notation, identifies each managed object. Each object identifier is
+ described using abstract syntax notation (ASN.1).
+ <img border="0" src="../../images/2.gif" align="absmiddle" width="12" height="12"></font></p>
+ <p>
+
+ <font face="Arial" size="2"> SNMP uses these object identifiers to
+ identify the MIB variables to retrieve or modify. Objects that are in
+ the public domain are described in MIBs introduced in Request for
+ Comments (RFCs). They are readily accessible at:
+ <a target="_blank" href="http://www.ietf.org">http://www.ietf.org</a></font></p>
+ <p>
+
+ <font face="Arial" size="2"> All vendors are encouraged to make their
+ MIB definitions known. Once an assigned enterprise value has been
+ given, the vendor is responsible for creating and maintaining
+ sub-trees.</font></p>
