this paper give us a detailed introduction of the CISOC SNMP framework for how a router configuration,Oracle -TimesTen memory database, I believe that reading this article knows something about SNMP management framework and SNMP notification.
understand SNMP management framework
SNMP (Simple Network Management Protocol, simple network management protocol) is a protocol of application layer, provides SNMP management and SNMP message format message communication between agents. It provides standard management framework of monitoring and management of equipment in the network environment, the common language of communication and the corresponding security control mechanism.
SNMP management framework consists of four components:
* a for the transmission of management information between SNMP entities management protocol
* MIB Library (Management Information Base, management information base)
SNMP manager is a system of using SNMP protocol to control and monitoring of the network node. The most common SNMP management network in which the environment is called a network management system (NMS, Network Management System). Network management system can not only refers to a specifically used for network management server, can also refer to an application to perform administrative functions of a network device. There are now numerous software and hardware manufacturers to provide network management system supporting SNMP protocol on the market, such as Cisco, CiscoWorks series of network management software products.
SNMP agent is a software module management device, used for maintenance is management information data management device and can make the management data reporting to a SNMP management system in time of need. The SNMP agent and the related MIB inventory is in network equipment (such as Cisco routers, switches, access servers,sun Certifications, etc.).
MIB library is a virtual data store space keeping network management information, composed of a plurality of groups of managed object composition. In the device MIB in a library is composed of multiple groups of their respective objects associated with multiple MIB modules defined. Each MIB module is SNMP MIB module using the standard written language, specific to follow the standards defined in the IETF (Internet Engineering Task Force, an international organization for Standardization) STD58, RFC2579 and RFC2580 in the document (see the article "MIB and RFC" section to understand the STD document and RFC document interpretation). Attention is required, each with a separate MIB module is sometimes called a MIB,Exams, such as equipment interface group MIB (IF-MIB) is set >
