These easy-to-use Windows applications are essential for anyone who is managing or developing SNMP-related applications or agents.  They allow users to receive and log SNMP Traps, monitor, manage, archive, and analyze data retrieved from SNMP Agents.  All NuDesign SNMP MIB Browsers come integrated with powerful MIB Compiler as well as with MIB Viewer and MIB Editor applications.  The MIB handling capabilities include automatic resolution of MIB IMPORT dependencies, and convenient management of loaded and available for loading MIB modules.

Visual MIB Browser Basic – provides basic support for SNMPv1 and v2.  It present the user with the MIB tree based GUI interface and performs simple Get or Walk operations on user configured SNMP agents.  It comes with full feature NuDesign’s MIB Compiler providing for compiling, viewing and editing of MIB modules.  It is licensed as free of charge SNMP application.

Visual MIB Browser – provides fully featured support for SNMPv1 and v2, allowing users to perform additional tasks such as auto-discovering SNMP Agents, setting alarm thresholds and alarms, sending and receiving Traps and Informs, then real-time data charting and graphing, performing Get, Set, Log or Walk operations on auto-discovered or pre-configured SNMP agents.  Please see Table 1 below for full list of Visual MIB Browser features.

Visual MIB Browser Professional – extends these capabilities with comprehensive SNMPv3 support, user assignable color-coded alarm priority settings, user definable MIB groups, database interfacing, VB scripting capabilities.  The support for SNMP Proxy Forwarder functionality has also been included to simplify configuration and use of rfc3413, Proxy MIB compliant agents.

With Release 6.0 of Visual MIB Browser Pro the user can enable SNMP Traffic Monitor and Analyzer functionality monitoring, capturing and storing SNMP packet exchanges between the MIB Browser and the Agent, an invaluable tool when pin-pointing difficult problems.  The SNMP Traffic Monitor is also available as a standalone product, however developers will benefit from having this powerful functionality available from within the Browser.

Also new is the SNMP CLI interface providing the user with complete control over the content of SNMP PDUs, for example issuing a Get Request to any object with user provided OID.

The SNMP developers and test departments find SNMP traffic monitoring, CLI interface and VB scripting capabilities of particular interest.  A number of enclosed scripting examples provide a framework for creation of user specific regression, stress or compliance testing suites.  With VB scripting the user can extend the SNMP MIB Browser’s user interface and functionality, for example a script could monitor the reception of notifications and forward summary notifications to other management application(s), based on the notifications that MIB Browser has received.

With the Release 6.0 NuDesign has further automated testing of customer’s SNMP Agent MIB’s implementations.  First the Browser determines which of the pre-loaded MIBs are implemented by the agent, then it provides for complete testing of MIB implementation.

The Read access with GetNext & Get is verified, Read-Only objects are confirmed to be not writable, Write access is verified as well.  The tests terminate with detailed report for every MIB / object tested and short summary, example of which is included below.


Of the modules currently loaded into MIB Browser, the agent at ‘ip address:161’ using SNMP version: 1 and read credentials: public, implements some or all of the following modules:


And following the detailed report, omitted here, a summary is provided:

RFC1213-MIB Test Results:

  • Objects tested = 174
  • No response to a Set on an object = 1
  • Objects not implemented or not instantiated = 21
  • Obsolete or deprecated objects implemented = 3
  • Writable objects implemented ReadOnly = 26
  • Object values not in range = 0
  • Object values not in enumeration = 1
  • Object values not the correct size = 0

  • interrogate “raw” your agent under development using Get, GetNext or GetBulk to any OID from SNMP CLI interface.
  • record and display SNMP packets in a “human readable form”, analyse those hard-to-debug SNMPv3 packet exchanges between the MIB Browser Pro and your SNMP Agent.
  • set up and use SNMPv3 Proxy mechanism in your v3 agents.
  • Query pre-configured SNMPv3 agents.
  • Save query results in a database for long term trends reporting.
