Version 2 (SNMPv2c, described in RFC 1902) is the second release of SNMP.Version 1 (SNMPv1, described in RFC 1157) is the initial implementation of SNMP.Simple Network Management Protocol (SNMP) is an interoperable standards-based protocol that allows for external monitoring of the Content Engine through an SNMP agent. Netflow originally introduced by CISCO has become a standard now (named IPfix) that has been implemented by many routers/switches Vendors. Regarding Performance Management on routers/switches for IP, CISCO soon realized that a more compact protocol than SNMP was needed to scale better for performance collection on IP networks. Collectively, these two events led the IETF to the creation of the NetConf protocol which is expected to be better aligned with the needs of network operators and equipment vendors. This was brought to the IETF and shared with the broader community. Around this same time, Juniper Networks had been using an XML-based network management approach.

The content and formatting of output was prone to change in unpredictable ways. Most notably was the unpredictable nature of the output. In addition, many equipment vendors did not provide the option to completely configure their devices via SNMP.Īs operators generally liked to write scripts to help manage their boxes, they did find the CLI lacking in a number of ways. This had a number of features that the operators liked, including the fact that it was text-based, as opposed to the BER-encoded SNMP. It turned out that operators were primarily using proprietary Command Line Interfaces (CLI) to configure their boxes. The results of this meeting are documented in RFC 3535. In 2002, the Internet Architecture Board and key members of the IETF’s network management community got together with network operators to discuss the situation. In the early part of the 21st century it became apparent that in spite of what was originally intended, SNMP was not being used to configure network equipment, but was mainly being used for network monitoring, i.e. The IETF developed SNMP in the late 1980s and it proved to be a very popular network management protocol. Recommendation gives the authors opinion about the best fit for every protocol, based on industry adoption, trends, and personal experience.
