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:

The Simple Times
newsletter published a special
issue on SNMPv3 in December 1997. The articles are written
by some of the SNMPv3 document editors in order to explain some
of the ideas behind the SNMPv3 specifications.
Implementations of the SNMPv3 specifications are being developed by
various vendors and research departments. The following list provides
links to the various implementation efforts. Please follow the links
to find more about the implementation status, the set of supported MIB
objects, the availability etc. The implementations are listed in

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
page. The package also inlcudes a MIB Browser tool to test
and monitor SNMP devices.

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.

Jochen Katz (SNMP++v3) or Frank Fock (AGENT++v3).
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 www.winsnmp.com. 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.]

Cisco Systems ships full SNMPv3 support in IOS version 12.0(3)T. It is
implemented for all IOS platforms that have 12.0(3)T based images. It
was specifically tested it on the 7200, 2500, 2600, 3640, as5300, rsp,
4000 and 4500. SNMP privacy is available only in crypto images, which
cost more, have certain export restrictions, and have the full suite
of Cisco security features.

MIMIC provides an inexpensive way for enterprises, device
vendors, management software developers and outsourcers to demo,
test, develop, train and certify management applications without
purchasing equipment and maintaining labs for those
functions. MIMIC has the ability to simulate up to 10,000
devices from one workstation. MIMIC simulations can be
distributed over multiple platforms for enterprise simulation
testing of even larger environments. MIMIC includes
user-friendly wizards for importing new MIBs, recording large
networks, creating device simulations and network topologies,
and provides full support for SNMP(v1, v2, v2c, v3), RMON(1, 2),
DHCP, TFTP, ToD, DOCSIS and MGCP, as well as Telnet and IOS.

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.

The iReasoning SNMP library is the industry leading SNMP
library, which provides a high performance, cross platform Java
API for building network management applications. All SNMP

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.

SimpleSoft's Automated SNMP Agent Tester, SimpleTester (version
3.0), now supports SNMPv3, in addition to SNMPv1 and

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.
