 | | Word of the Day |  | | Daily updates on the latest technology terms | February 24, 2020 | | | SNMP | | Simple Network Management Protocol (SNMP) is an application-layer protocol for monitoring and managing network devices in a local area network (LAN) or wide area network (WAN). The purpose of SNMP is to provide network devices such as routers, servers and printers with a common language for sharing information with a network management system. The protocol's client/server architecture has three components: an SNMP Manager, an SNMP Agent and a Management Information Base (MIB). The SNMP Manager acts as the client, the SNMP Agent acts as the server and the Management Information Base acts as the server's database. When the SNMP Manager asks the Agent a question, the Agent uses the MIB to supply the answer.
There are multiple versions of the SNMP protocol, and SNMP is so popular that most network devices come pre-bundled with SNMP Agents. In order to make use of the protocol, however, network administrators must first change the default configuration settings of their network devices so SNMP Agents can communicate with the network's management system. SNMP is part of the original Internet Protocol Suite as defined by the Internet Engineering Task Force (IETF). The most recent version of the protocol, SNMPv3, includes security mechanisms for authentication, encryption and access control. Continue reading...
