The SNMP architecture comprises two main components, managers and agents, apart from a set of standards that are used for controlling the interaction between the components. The SNMP managers and agents communicate with each other by using SNMP commands. These commands are defined in RFC 1157. The managers control the functioning of the agents. The agents provide the information required by the managers by interacting with devices such as computers and routers. These devices are also called managed devices. The protocol that is used for communication between the managers and the agents is SNMP and is also referred to as the management protocol.
