Simple Network Management Protocol (SNMP) is used ubiquitously to monitor and control any device over the network by exchanging SNMP messages. The SNMP, defined by IETF, has gained significant popularity among the software, hardware, telecom, and network industries. SNMP was derived from its predecessor SGMP (Simple Gateway Management Protocol). This is considered as a de facto and standard client-server protocol to transfer the management information over the network. In 1988, the initial version of SNMP (version 1) used TCP/IP suite and supported GET, GET-NEXT, and SET methods to get management information from the managed node. The SNMPv2c was introduced with improvements in performance, security, and confidentiality with support of GET-BULK.
