A network management system contains: several (potentially
many) nodes, each with a processing entity, termed an agent,
which has access to management instrumentation; at least one
management station; and, a management protocol, used to convey
management information between the agents and management
stations. Operations of the protocol are carried out under an
administrative framework which defines both authentication and
Network management stations execute management applications
which monitor and control network elements. Network elements
are devices such as hosts, routers, terminal servers, etc.,
which are monitored and controlled through access to their
Management information is viewed as a collection of managed
objects, residing in a virtual information store, termed the
Management Information Base (MIB). Collections of related
objects are defined in MIB modules. These modules are written
using a subset of OSI's Abstract Syntax Notation One (ASN.1)
, termed the Structure of Management Information (SMI) .
The management protocol, version 2 of the Simple Network
Management Protocol , provides for the exchange of messages
which convey management information between the agents and the
management stations, including between management stations.
It is the purpose of this document to define managed objects
which describe the behavior of a SNMPv2 entity acting in both
a manager role and an agent role.
