Rapid prototyping and development tool
for building SNMP (Java Micro Edition) agents which are compatible
with J2ME CDC specifications.
Introduction
WebNMS SNMP Agent Toolkit Java Edition is a
productive development environment for building Micro Edition
(J2ME) SNMP agents compatible with CDC specifications.
The existing platforms and specifications
support only devices that have more memory, powerful networking
capabilities, intuitive user interfaces, etc. These platforms
and specifications do not support the embedded devices such
as high-end personal digital assistants (PDAs), set-top boxes,
etc. that have less memory. Hence, we need J2ME CDC specifications-based
solution that provides standard-based SNMP-compliant remote
management for the embedded devices.
WebNMS Micro SNMP agents are newly designed
to be ported in the J2ME CDC environment that targets the
devices with less-memory and limited-resource requirement.
The toolkit renders end-to-end development of the Micro SNMP
agent (can be developed in the normal J2SE Platform) that
can be easily deployed to manage the connected device. With
this feature, WebNMS enables you to port the Micro SNMP
agent into such less-memory devices for providing SNMP manageability.
Key Features
Complete SNMPv1 and SNMPv2c support.
Support for traps, notifications, and informs.
Atomicity or rollback support while processing multi-varbind
SNMP SET requests.
TrapForwardingTable to maintain the Manager's information.
Transport provider framework to accommodate proprietary
protocols.
Developer Benefits
Agent Development Environment: Enhanced and integrated
tools reduce the time to develop SNMP agent, increase developer
productivity, and offer reduced time-to-market. The tools
can be used in the normal J2SE environment to develop the
agent, which can then be ported in devices having limited
resources.
Standards-based Architecture: Built on standard technologies
such as SNMP, it offers a viable platform for integration
with any standard management console.
Java Micro Edition SNMP Agent Development Experience
SNMP Agent Toolkit offers a complete development experience.
To develop the J2ME (Micro Edition) SNMP agents in a normal
J2SE environment:
Create and edit any MIB(s) in the MIB Editor.
Load any MIB(s) in the MIB Compiler.
Generate agent using MIB Compiler. A basic SNMP framework
is generated based on specifications with provisions for
developers to add their custom code.
Compile the agent using MIB Compiler after completing
instrumentation. Now the agent is ready and can interact
with any standard SNMP manager.
Test and verify the developed agent using MIB Browser
that is bundled along with the toolkit.
The developed J2ME SNMP agent is ready to be deployed on
platforms with less memory and embedded platforms, and it
can be seamlessly integrated with any Network or Enterprise
Management Console.
The Java Micro Edition SNMP agent runtime architecture explains
the components and their functions.
Java Micro Edition SNMP Agent Components
Transport Provider: It facilitates the communication
between the SNMP manager and the SNMP agent. SNMP messages
require transport protocol for their transmission. WebNMS
SNMP agent (Micro Edition) supports UDP/IP and TCP/IP as the
transport protocol.
Message Processing Unit: It extracts data
from the request and determines the appropriate SNMP agent
stub capable of handling the query. Finally, the output received
from the SNMP agent is packaged as a response message and
sent back.
Instrumentation: To get the device or application
specific data, some files in the generated source files need
to be instrumented to include the desired function. This will
depend on how the MIB is defined, how the data associated
with the MIB can be accessed, how it needs to be delivered
to the Manager, etc.
Supported SNMP Standards

SNMP standards:
