Abstract
Abstract A MIB manager including set of software interfaces, semantics, procedures and data structures that work together as a system to dynamically manage a tree of SNMP data objects identified by a standard object identifier (OID) along with each object's value. An agent uses the interface of the MIB manager to add and delete MIB objects by OID. When one or more new objects are added to the MIB tree, the agent provides the MIB manager with references to subroutines within the agent and external to the MIB manager, which subroutines operate to manage the identified objects by monitoring and controlling the objects' values. This enables the MIB manager to be implemented in a manner independent of the application and hardware. The MIB manager allows agent to add new objects at any level within the MIB tree, thus allowing modification at any desired degree of granularity. The agent may add a single leaf element, a table row, an entire table or an entire branch of the MIB tree. If the agent adds a branch to the MIB tree through the MIB manager interface, where the branch is itself a tree of MIB objects, then the agent includes proper procedures for managing the objects and values for that branch. Security information may also be defined for new objects, either by referencing an existing access rights definition or by referencing new access rights.
