Simple Network Management Protocol

Simple Network Management Protocol (SNMP) is an application-layer protocol designed to facilitate
the exchange of management information between network devices. By using SNMP-transported data
(such as packets per second and network error rates), network administrators can more easily manage
network performance, find and solve network problems, and plan for network growth.
Two versions of SNMP exist: Version 1 and Version 2. Most of the changes introduced in Version 2
increase the security capability of SNMP. Other changes increase interoperability by more rigorously
defining the specifications for SNMP implementation. SNMP is part of a larger architecture called the
Internet Network Management Framework (NMF), which is defined in Internet documents called RFCs.
The SNMPv1 NMF is defined by RFCs 1155, 1157, and 1212, and the SNMPv2 NMF is defined by RFCs
1441 through 1452.
SNMP is a popular protocol for managing diverse commercial internetworks and those used in
universities and research organizations. SNMP-related standardization activity continues even as
vendors develop and release state-of-the-art, SNMP-based management applications. SNMP is a
relatively simple protocol, yet its feature set is sufficiently powerful to handle the difficult problems
presented in trying to manage today's heterogeneous networks.
