How Network Management Systems Work Simple Network Manegement Protocol (SNMP) Management Information Base (MIB) TCP/IP (Transmission Control Protocol/Internet Protocol) Network Switch
Simple Network Manegement Protocol (SNMP) A set of protocols for managing complex networks. Thefirst versions of SNMP were developed in the early 80s.SNMP works by sending messages, called protocol dataunits (PDUs), to different parts of a network. SNMP-compliant devices, called agents, store data aboutthemselves in Management Information Base (MIB) andreturn this data to the SNMP requesters.
Management Information Base (MIB) A database of objects that can be monitored by anetwork management system. Both SNMP and RMONuse standardized MIB formats that allows any SNMP andRMON tools to monitor any device defined by a MIB.
TCP/IP (Transmission Control Protocol/Internet Protocol) TCP/IP is the basic communication language or protocolof the Internet. It can also be used as a communicationsprotocol in a private network (either an intranet or anextranet). When you are set up with direct access to theInternet, your computer is provided with a copy of theTCP/IP program just as every other computer that youmay send messages to or get information from also has acopy of TCP/IP.
Network Switch The network switch, packet switch (or just switch) playsan integral part in most Ethernet local area networks(LANs). Mid-to-large sized LANs contain a number oflinked managed switches.
