SilverCreek Product Brief

Executive Overview

Whether your job is to find SNMP compliance problems or to fix them, the SilverCreek SNMP test suite is your most valuable ally. SilverCreek is a software product for design, quality assurance, and test engineers to find and fix bugs in their SNMP agent implementations. The SilverCreek SNMP software is so easy to use that anyone who can navigate a graphical user interface can quickly run a battery of individual, comprehensive tests.

The tests are designed to detect and diagnose implementation errors in private and standard MIBs as well as SNMPv1, v2c, and v3 stacks and implementations. Yet SilverCreek is so powerful, extensible, and flexible, power users can create the ideal solution for virtually any testing environment.

Authoritative

SilverCreek is the Authoritative SNMP Test Suite -- designed to test implementations of the Simple Network Management Protocol (SNMP agents) and standard and private MIBs (Management Information Bases). SilverCreek incorporates thousands of small, single function tests written in the Tcl scripting language to exercise one or a small number of parameters. The syntactic tests verify protocol compliance, error and exception handling, and boundary condition behavior. The functionality tests (semantic tests) verify performance, trap/alert/event/notification handling, counter accuracy, security, and many other implementation specific areas.

Thorough and Extensible

SilverCreek's SNMP engine is written in C++. The testing interface is written in the interpretive Tcl/Tk scripting language. Users may modify or extend test scripts without programming. Using the SilverCreek management information base (MIB) browser is just as easy. Clicking on any leaf automatically launches the SNMP Command Tool, which allows users to view the contents of the agent’s object identifier (OID) tree and issue GETs and SETs. Because the MIB browser combines SNMP GET and NEXT requests on modified object identifiers, it discovers MIB branches in a manner that is more efficient, more thorough, and more accurate than the average MIB walk. Combined with the MIB Lookup Tool and support for private MIBs, the SilverCreek MIB Browser boosts productivity to new levels.

Advisory Board

The SilverCreek SNMP Test Suite was developed and refined by InterWorking Labs, Inc. with the help of the Advisory Board comprised of key SNMP technology experts from the IETF. Attending the IETF meetings, commenting on drafts in progress, and evaluating interoperability issues with other participants assures the best understanding of the standards documents which translates into meaningful tests. This results in the most accurate, credible, and comprehensive test suites possible.

A Rich Toolset

For probing, sniffing, and inspecting individual objects, components or subsystems of your product's SNMP implementation, the toolset includes:

MIB Tools

  • A MIB browser that actively probes the agent for the true value of objects
  • A MIB compiler that allows you to add, compile, and automatically test your private MIB, or any IETF MIB
    • Add and compile any MIB (private or standard)
    • Automatically compile and load multiple MIBs (all at once)
    • Add and compile an agent-capabilitiy MIB
    • Select one or more branches of MIBs for testing
  • A MIB Lookup Tool for quick and convenient access to information about a MIB object. Provides basic information such as descriptor name, OID, syntax, access, status, and index.
  • A MIB Scope Tool to isolate a portion of the agent's objects to focus testing on a specific set of objects
  • MIB Compare Tool
  • MIB Walker
  • MIB Table Inspector
  • MIB Dictionary
  • Validate MIBs by 6 Severity Levels

SNMP Traps, SNMP Alerts, SNMP Informs

  • A Trap Monitor to visually examine the contents of all traps
