SNMP Version 3 (SNMPv3) SNMPv3,network management,SNMP security

This web page provides information about the Simple Network Management Protocol Version 3 (SNMPv3). The SNMPv3 specifications were approved by the Internet Engineering Steering Group (IESG) as full Internet Standard in March 2002. The SNMPv3 specifications were previously approved by the IESG as Draft Standard in March 1999. The SNMPv3 specifications primarily add security and remote configuration capabilities to SNMP.


The core SNMPv3 specifications:

AdventNet AdventNet SNMPv3 API, written completely in Java, provides support for all versions of SNMP, and includes comprehensive support for creating network management applications. It is suitable for creating both web based client-server applications as well as stand-alone GUIs realized as Java applets or applications. You can download the API for development use from AdventNet's web page. The package also inlcudes a MIB Browser tool to test and monitor SNMP devices.
For more information, contact AdventNet.
SNMP++v3/AGENT++v3 SNMP++v3 and AGENT++v3 are C++ APIs allowing the development of SNMP managers and agents respectively. Both APIs support SNMP v1, v2c and v3. The SNMPv3 support includes MD5 and SHA authentication as well as DES, IDEA, and AES privacy. You can download both APIs free of charge from the Agent++ web page for development use. SNMP++v3 is based on Peter Mellquist's (Hewlett Packard) SNMP++2.6.
For more information contact Jochen Katz (SNMP++v3) or Frank Fock (AGENT++v3).
Applied SNMP, LLC SNMPv3-enabled WinSNMP v3.0 API shipping since October 2000 to developers (via SDK product) and to end-users (via the Auto*Manage application suite). All pre-existing SNMPv1 and SNMPv2c WinSNMP applications are 100% compatible with the WinSNMP v3.0 implementation without modification or rebuilding. SNMPv3 support via addition to the WinSNMP API (constituting v3.0) are described in the Addendum (winsnmp3.htm) available at Applied SNMP will release its AgentX tool set (master agent and SDK) in 1Q02 with full support for SNMPv1, SNMPv2c, and SNMPv3, over WinSNMP v3.0.
[Note: ACE*COMM transitioned its WinSNMP product family to a dedicated entity - Applied SNMP - in early 2000 for on-going support, development, and sales.]

iNiche InterNiche has implemented the latest standard SNMP protocols (SNMP v1, v2c and v3) as royalty-free Agent SDKs. Designed specifically for the requirements of next-generation embedded designs, the Agent software is memory-efficient (from 12KB), portable ANSI "C" source code for any conceivable CPU, MPU or SOC implementation. SNMP can be easily added to the smallest Internet-enabled devices using existing IP stacks, or NicheStack™, InterNiche's embedded TCP/IP stack. The v1 and v2c Agents require no multitasking or RTOS facilities — A routine (entry point) is called whenever a SNMP request is received. SNMPv3 requires minimal memory services and a timer, resources that can be supplied by a lightweight multi-tasking scheduler (such as, NicheTask™), or by a RTOS (ÁC/OS-II or VxWorks, etc). MIB Tables may be populated dynamically and packets are allocated dynamically (so that multiple packets can be serviced at the same time). Tables can be populated via a configuration file, CLI, or by SNMP GET/SET requests. The InterNiche SDKs include sample DOS and Windows (WinSock) SNMP Agent implementations.
For more information, contact InterNiche Technologies, Inc.
iReasoning The iReasoning SNMP library is the industry leading SNMP library, which provides a high performance, cross platform Java API for building network management applications.

For more details, contact Radware Inc..
xxx Rig Consulting, Inc. has announced the release of ComSNMP 1.0. ComSNMP a short name for `Component SNMP' and is a set of generic light weight components out of a box for Windows 32 bit platform which C, C++, VB and web programmers can use to develop NMS applications requiring SNMP V3. The components will aid Rapid Application Development (RAD) of network management software on Windows 32 bit platforms or enhance your existing software to support SNMP V3. Programmers can use either the COM components (ideal for scripting languages) or link statically to the component libraries (ideal for C, C++ applications). The components go beyond being just being RFC compliant in that programmers can focus on the NMS application development and not worry too much about how SNMP works. Some of the method calls address what has been done over and again in an attempt to optimize performance, for example using a single PDU to get response for multiple SNMP Objects.

SmartMIB SmartMIB is the next generation of IT Network Management Tools to automate IP management information. SmartMIB is a "Higher-Level Manager" designed to understand, deal with, and cater to the complexity of the SNMP network management protocol structure. It introduces a proprietary SNMP Operating System (SOS) Language. The SOS Language enables network administrators to drive and custom fit the under-laying management processes of their prospective networks in accordance to their own (maybe) unique management requirements and policies. SOSL's SNMPv3 support includes MD5 and SHA authentication. Using SmartMIB It is simply a matter of adding the managed device credentials in the "Secured Devices" inventory to force all communications to that particular device to be secured through SNMPv3.
For more information, contact SmartMIB.
