The IETF created SNMP to allow remote management of IP based devicesusing a standardized set of operations. It is now widely supported by servers printers hubs switches modems UPS systems and (of course) Cisco routers.The SNMP set of standards define much more than a communication protocol usedfor management traffic. The standards also define how management data should beaccessed and stored as well as the entire distributed framework of SNMP agents andservers. The IETF has officially recognized SNMP as a fully standard part of the IPprotocol suite. The original SNMP definition is documented in RFC 1157.In 1993 SNMP Version 2 (SNMPv2) was created to address a number of functionaldeficiencies that were apparent in the original protocol. The added and improvedfeatures included better error handling larger data counters (64bit) improved efficiency (getbulk transfers) confirmed event notifications (informs) and most notably security enhancements. Unfortunately SNMPv2 did not become widelyaccepted because the IETF was unable to come to a consensus on the SNMP security features.So a revised edition of SNMPv2 was released in 1996 which included all of the proposed enhancements except for the security facility.
