Tables in the MIB are represented as a sequence of rows. Each row in the table represents an instance of the table. Each row is comprised of a set of columns, each of which has a unique object identifier (OID) and a value. The row is identified by a primary index, which is used to uniquely identify each instance of the table. Other columns in the row may be indexed to allow for more efficient lookups, and may also include data types such as strings, integers, and enumerations. The MIB structure allows for tables to be defined with varying numbers of columns and unique indices to support the needs of different applications.
