An agent returns a response to the request from a manager. +when special phenomena apparatus rebooted occur, a trap is sent to a +manager from an agent. + +MIB (Management Information Base) is the database of the management +information about the network apparatus which exists in the network +apparatus corresponding to SNMP. The thing of each management information +stored in MIB is called object (Object).OID (Object IDentifier),it is the +discernment child rejected in order to distinguish each object,and is also +called an object discernment child. the object is managed by the tree +structure. + +Community name is the exchange between a manager and an agent, and has a +role like a password. That is, if the right community name is not specified +when publishing a request from a manager to an agent, in an agent side, +it will be interpreted as unlawful access. + + +1.)
