RFC 3412 - Message Processing and Dispatching for the Simple Network Management Protocol (SNMP) It includes proactive connectivity monitoring, fault verification, and fault isolation for large Ethernet MANs and WANs. IT administrators use SNMP monitoring to detect and manage devices, gain insights into performance and availability, and ensure the health of their network. SNMP originated in the 1980s at the time when organizational networks were growing in both size and complexity. In order to effectively monitor network activity, SNMP relies on an architecture consisting of the following: Together, these components gather information to bring back to the network requester. SNMP has a number of different abilities including the ability to monitor, configure and control network devices. That means anyone with access to the network could run “sniffing” software to intercept information about the network. from a control room to the antenna in a satellite earth .

Read-Write mode allows to modify the value of variables on the Management Information Base (MIB) of an SNMP managed device. Backups are a routine part of any network maintenance checklist, and should never be missed. A device specifies important details such as the network hostname, SNMP parameters, and host type. SNMP, short for Simple Network Management Protocol, is a widely used protocol and an essential piece of any network management strategy.
