Windows Vista and Windows Server 2008 support SNMPv1 and SNMPv2c. This topic provides basic information about each of these versions of SNMP.

Simple Network Management Protocol version 1 (SNMPv1) is the earliest version of the protocol. SNMPv1 is defined by RFC 1157, RFC 1155, and RFC 1212. For SNMPv1, security is based on community strings.

Simple Network Management Protocol version 2c (SNMPv2c) is defined by RFC 1901, RFC 1905, and RFC 1906. SNMPv2c updates the protocol operations and data types that were defined in SNMPv2p. SNMPv2c, known as "community string-based SNMPv2," uses SNMPv1 community-based security.
