  • the SNMP protocol is widely used for getting and setting values from an Internet- based programmable device.
  • the advantage of the prior art SNMP protocol usage was the opportunity for a user to buy a number of configuration tools, including an open view interface (OVI) , from a vendor and to write a proprietary management information base (MIB) module (MIB file) that can be plugged in into interface .

  • Another advantage of using SNMP protocol is the ability to interrogate the Internet-based programmable device by using the SNMP protocol without prior knowledge of the particular programmable device. This is possible because the SNMP protocol uses the get/next model of interrogation in its MIB files. In the get/next model of interrogation the SNMP protocol uses different MIB files written for different applications but all having the same topological structure as a tree of different variables, but with the same trunk.

  • Each variable is given a unique identity based on the identity of its class and its identification within its class.

  • the operand to a set is a list of pairs. Each pair includes the identity of a variable and its desired value.
  • Set operations are used to configure and control a managed system.
  • the first type of retrieval operation requires that the identities are those that match exactly the identity of returned variables . This retrieval operation is used when the identity for each variable is known. There is a single operation of this type, called get .
  • the second type of retrieval operation uses each identity in a request as an approximation of the identity for a variable.
  • Each returned identity is the one assigned to the first accessible variable whose identity is greater than the given identity.
  • the get, getnext and getbulk operations are used to moni- tor a managed system.
  • SNMP operations occur through message exchange over a message transport service.
  • the format of messages is defined using a subset of the Ab- stract Syntax Notation One (ASN.l) language. This format, called an abstract syntax, is independent of the representation of data on any particular system. To transmit a message, it should be first converted into a string of octets (bytes) .

  • the second event report operation inform uses two messages: the inform message and the response message, as illustrated in diagram 84 of FIG. 2C.
  • An SNMP message includes administrative information and an SNMP Protocol Data UNIT (PDU) .
  • the PDU identifies the type of the message.
  • SNMP messages are exchanged between processes called SNMP entities.
  • An SNMP entity may be designed to process only one message at a time (i. e., be implemented as single-threaded), or may be designed to process multiple messages concurrently (i. e., be implemented as multi-threaded) .
  • An SNMP entity can play one of many roles during message exchange. The role is determined by the message type and message originator.
  • An SNMP entity is called SNMP manager (72 of FIG. 1) if it assumes the operational role to generate requests to retrieve and modify management information, receive the responses to requests, or to receive event reports.
  • An SNMP entity is called SNMP Agent (70 of FIG. 1) if it assumes the operational role to receive, pro- cess, and respond to requests, and to generate event reports.
  • An SNMP Agent should have access to network management information to respond to requests, and should be notified of internal events to generate reports.
  • An SNMP entity can also play a dual role of being both an SNMP Agent and an SNMP manager (68 of FIG. 1) . However, in describing SNMP message exchange, an entity should perform either as a manager, or as an Agent for a particular message.
  • Dual-role entities are typically used to forward SNMP messages (an SNMP proxy) , or to consolidate and synthesize information from many systems and make that information available to a higher-level manager (a mid-level manager) .
  • a Client generally is an SNMP manager
  • a server is an SNMP Agent.
  • SNMP message exchange one needs only a simple connectionless (i. e., datagram) transport service.
  • Examples includes the User Datagram Protocol (UDP) from the Internet protocol suite, the Connectionless-mode Transport Service (CLTS) from the OSI protocol suite, the Datagram Delivery Protocol (DDP) from the AppleTalk protocol suite, the Packet Exchange protocol (PEP) from the Novell IPX protocol suite, or any form of interprocess communication message within a single system.
  • the SNMP protocol is stateless, that is the SNMP protocol does not keep information about or for the entities after an operation has been performed. Any such information is kept by the entities themselves .
  • the second component of the framework is a definition of management information and events that is specified in a plurality of documents called the Structure of Management Information (SMI) .
  • the SMI includes the model of management information, the allowed data types, and the rules for specifying classes (or types) of management information.
  • An SNMP system is managed by retrieval and modification of management information.
  • Each class (or type) of management information is called an object or object type .
  • a specific instance from a class of management information is called an SNMP variable or an object instance.
  • the definition of an object type includes its data type, the maximum allowed access, its assigned iden- tity, how instances are identified, and its semantics (or behavior) .
  • SNMP uses an identification scheme found in ASN.l to uniquely identify items for all space and time. An identifier in this scheme is called an object identifier (or OID) .
  • OID object identifier
  • the permanent assignment of an OID value, an identity, to an item is called registration .
  • SNMP uses OIDs to iden- tify many types of items. Besides the data types and rules for specifying management information, the SMI also includes some administrative assignments. These assignments are used to organize the definitions of management information into those targeted for the Internet Engi- neering Task Force (IETF) standards track, experimental ones within the IETF, and proprietary ones developed by vendors of SNMP-based management systems. The SMI also includes rules for specifying implementation compliance requirements, and actual implemented characteristics of SNMP Agents.
