About the Microsoft WinSNMP Implementation

The Microsoft WinSNMP implementation complies with WinSNMP version 2.0. It supports all the functions and operations defined in both the WinSNMP version 1.1a specification and the WinSNMP version 2.0 Addendum. The implementation provides the following services for WinSNMP applications:

• Manages communications to and from management entities. The entity can reside on the local computer or be connected through a local or wide-area network, or the Internet. For more information, see Levels of SNMP Support.
• Hides the details of SNMP protocol, Abstract Syntax Notation One (ASN.1), and the Basic Encoding Rules (BER) for describing transfer syntax.
• Verifies the correctness of PDUs and rejects invalid PDUs. For more information, see Working with Protocol Data Units.
• Transforms SNMPv2C PDU types when necessary in accordance with the relevant RFCs.
• Converts SNMPv1 traps from an SNMPv1 agent to SNMPv2C traps in accordance with RFC 1908, "Coexistence between Version 1 and Version 2 of the Internet-standard Network Management Framework." For more information, see Translating Traps from SNMPv1 to SNMPv2C.
• Supports the application's retransmission policy and provides retransmission execution support. For more information, see The WinSNMP Database and About Retransmission.
• Provides entity and context translation support for the application. For more information, see The WinSNMP Database and Setting the Entity and Context Translation Mode.
