Chapter 1. Introduction

1.1 Overview RobustOS (hereinafter referred to as “the ROS”) is a new operating system for Robustel's IoT gateway released in

2015. It is a modular and open software platform which could support third party development based on SDK/API.

Meanwhile, it supports different routing and VPN protocols for different application scenarios. This newer platform

provides a different web configuration interface than the existing platform.

SNMP is used mostly in network management systems to monitor network-attached devices thus ensuring the

management on them. R3000 supports SNMP for remote management, which acts as a network node that

implements an SNMP interface and allows unidirectional (read-only) or bidirectional (read and write) access.

This application note is written for customers who have good understanding Robustel products and experienced in

SNMP. It shows customer how to configure and test the SNMP for R3000 router through the cellular network.

*This application note applies to the ROS firmware of R2000 and R3000. However, the followings will take R3000

as an example*

1.2 Assumptions

The features of SNMP have been fully tested and this Application Note is written by technician who is familiar with

Robustel products and the application requirement.

This Application Note is based on:

Product Model：Robustel GoRugged R3000 industrial router.

Firmware Version : R3000_S_V3.0.3

Configuration: This Application Note assumes the Robustel products are set to factory default. Most

configuration steps are shown if they are different from the factory default settings.

1.3 Rectifications

Appreciate for the corrections and Rectifications to this Application Note, and if there are requests for new Brief

Notes please also send to email address: support@robustel.com .

Chapter 2. Application Topology

1. R3000 dials up to connect to the Internet. 2. Manager PC accesses to R3000 by means of accessible IP of R3000 or VPN technology. 3. Manager PC can manage R3000 to get its status via SNMP protocol.

Note: In this Brief Note, we use Intranet for testing instead of Cellular WAN. R3000 WAN IP address (Eth0) is

172.16.100.22/16 .
