MIB Browser Version 11 User Guide

The iReasoning MIB browser is a powerful and easy-to-use tool powered by iReasoning SNMP API. MIB browser is an indispensable tool for engineers to manage SNMP enabled network devices and applications. The iReasoning MIB browser allows users to load standard, proprietary MIBs, and even some mal-formed MIBs. It also allows them to issue SNMP requests to retrieve SNMP agents' data, or make changes to agents. A built-in trap receiver can receive and process SNMP traps according to its rule engine.

Requirements


Download and Run MIB Browser

1. Download MIB browser installer or zip file. On Windows, run setup.exe to install MIB browser. On Mac OS X, Linux and other UNIX platforms, unzip it to the desired directory.

2. Run MIB Browser:

On Linux/UNIX, if you login as a non-root user and need to run trap receiver at port 162 (or any port under 1024), start MIB browser using the following command:

sudo browser.sh

Enterprise Edition

Trap receiver and watches functions run as a system service. Watches function supports action, which means you can configure actions (sending emails or traps) when a MIB object's value violates a pre-configured threshold.

On Windows platform, the service starts up automatically. On Linux/MAC OS X, you need to configure system to execute $INSTALL_DIR/lib/runserver.sh on startup.

Menu Items of Trap Receiver

Trap Filter button

Start Trap Receiver button

Stop button

Stop the trap receiver.

Add Trap Rule

Add a new rule for processing traps. If a row of trap table is selected, then the dialog will populate the fields with some data from the row.

All rules will be applied for an incoming trap, except that a rule specifies that the trap should be ignored. Rules are ordered by their names. So you can modify rule's name to change its execution order. For example, rule A and B have the same conditions, but A sets severity to low and B sets severity to medium. Because B is applied after A, the final severity will be set to medium.

Screenshot of adding trap rule:

Rule Conditions:
