It is important to understand the modular SNMPv3 architecture as defined by [RFC3411] and enhanced by the Transport Subsystem [RFC5590]. It is also important to understand the terminology of the SNMPv3 architecture in order to understand where the Transport Model described in this document fits into the architecture and how it interacts with the other architecture subsystems. For a detailed overview of the documents that describe the current Internet-Standard Management Framework, please refer to Section 7 of [RFC3410].

              Transport Layer Security (TLS) Transport Model            for the Simple Network Management Protocol (SNMP)


   This document describes a Transport Model for the Simple Network    Management Protocol (SNMP), that uses either the Transport Layer    Security protocol or the Datagram Transport Layer Security (DTLS)    protocol.  The TLS and DTLS protocols provide authentication and    privacy services for SNMP applications.  This document describes how    the TLS Transport Model (TLSTM) implements the needed features of a    SNMP Transport Subsystem to make this protection possible in an    interoperable way.

   This Transport Model is designed to meet the security and operational    needs of network administrators.  It supports the sending of SNMP    messages over TLS/TCP and DTLS/UDP.  The TLS mode can make use of    TCP's improved support for larger packet sizes and the DTLS mode    provides potentially superior operation in environments where a    connectionless (e.g., UDP) transport is preferred.  Both TLS and DTLS    integrate well into existing public keying infrastructures.

   This document also defines a portion of the Management Information    Base (MIB) for use with network management protocols.  In particular,    it defines objects for managing the TLS Transport Model for SNMP.
