Rapid prototyping and development tool for building SNMP agents, TL1 agents, and CLI agents in ANSI C.

Overview

WebNMS Agent Toolkit C Edition is a rapid application development platform to generate standalone SNMP agents. It offers end-to-end development solutions to compile, test, and develop SNMP v1, SNMP v2c, SNMP v3 with VACM authorization, and SNMP v3 with USM authorization. SNMP agent developers can increase productivity with easy-to-use GUIs for configurations, such as master agent - subagent and SNMP proxy configuration. WebNMS Agent Toolkit C Edition offers complete development experience in building SNMP v1, SNMP v2c, and SNMP v3 agents.

WebNMS Agent Toolkit C Edition’s generated source files are ported and tested in leading operating systems, such as Windows Vista, 2000, XP, and NT, Solaris, Linux, Unix, Free BSD, Net BSD, HP-Unix, and OS-2. The developed SNMP agents are fully supported in embedded operating systems, such as VxWorks, QNX Nutrino, Windows CE, and OSE. Agent source files can also be easily ported to other new operating systems.

Key Features

• Complete SNMPv1, SNMPv2c, and SNMPv3 support.
• Highly scalable master agent - subagent architecture to handle distributed management environment.
• Support for traps, notifications, and informs.
• Authentication support for data security in networks and systems.
• USM, VACM, co-existence, and notification filtering mechanism support in SNMPv3.
• Atomicity or rollback support while processing multi-varbind SNMP SET requests.
• Transport provider framework.
• Heart Beat mechanism between master and subagent with subagent LinkUp/ LinkDown trap support.
• Trap forwarding and trap filtering in master agent.
• SNMPv3 Admin tool for manipulating USM and VACM tables at runtime.
• IPv6 addressing support in addition to IPv4
  

Developer Benefits

• End-to-End tools enable complete agent development cycle to reduce time-to-market.
• Intuitive visual MIB Editor to create and edit SNMP MIBs.
• MIB Compiler (Agent Compiler) to generate and compile the code to build an agent.
• Incremental agent development support through the concept of project workspace.
• Complete testing of developed SNMP agent using MIB Browser.
• Value added services, such as persistence, logging, and database storage.

SNMP Agent Developer Experience

WebNMS Agent Toolkit C Edition offers a productive six-step agent development experience for standalone SNMP v1, SNMP v2c, and SNMP v3 agents.

1. Define / Edit MIBs: MIB Editor offers user-friendly GUIs to define and edit MIBs, design the data layout, and data types conforming to ASN.1 syntax.
2. Generate Source Code: The defined MIBs can be loaded into the Agent Compiler to generate code that offers the basic SNMP agent framework.
3. Add Desired Instrumentation: Once the basic framework is ready, developers can add their necessary instrumentation to meet their specific requirements.
4. Compiling the Generated Source: The generated SNMP agent framework and specific instrumentation code needs to be compiled to generate the SNMP agent with desired functionality.
5. Test the Developed SNMP Agent: The developed agent needs to be queried and tested using MIB Browser.
6. Package and Deploy: The developed SNMP agent is ready to be packaged and deployed in the target environment.

SNMP Agent Runtime Architecture

WebNMS SNMP agent runtime architecture is standards based and open architecture offering you advantage of standard communication for integration. The architecture components and functions are explained below:

Standalone SNMP Agent Components

• Transport Provider: It facilitates the communication between the manager and the agent. SNMP messages require transport protocol for their transmission. WebNMS SNMP agent supports UDP/IP and TCP/IP as the transport protocol.
• Security: This module ensures the authenticity of the received request before dispatching it for further processing. Unauthenticated requests are dropped.
• Message Processing Unit: It undertakes the responsibility of extracting data from received messages and processing them. It determines the appropriate agent stub capable of handling the query. Finally, the output received from the agent stub is packaged as a response message and sent back.
• Agent Stubs: It contains the management information exposed by the agent about the application or device. Instrumentation of the agent stub enables communication between the agent and the application/device being managed. The information retrieved from the application/device is forwarded to the message processing unit.
