Issue
I/A Series R2 and G3 MIB files
Environment
I/A Series R2 SNMP integration
I/A Series G3 SNMP integration
Cause
A Management Information Base (MIB) describes a database of objects that can be monitored by a network management system. SNMP uses standardized MIB formats that allow any SNMP tool to monitor any device defined by a MIB. The Tridium MIB defines the information that can be exposed for a I/A Series Niagara station running the SnmpService.
The third party system is having trouble reading the SNMP traps from I/A Series using the MIB file that was sent to them.
Resolution
Ensure that the correct MIB file is used.
Starting in I/A Series R2 version 2.301.528 and above, a new TridiumR2-MIB was created that is supported by R2 Snmp stations. This was created because of the need to differentiate Tridium MIB object identifiers between R2 and G3.
I/A Series G3 versions 3.4 and earlier uses TridiumR3-MIB.my MIB file. To view this file in WorkBench, go to 'File' > 'Open' > 'Open Ord' (or shortcut Ctrl + L) and key in 'local:|module://snmp/tridiumMib/TridiumR3-MIB.my'.
Starting from I/A Series G3 versions 3.5 and above, there is a Workbench function (right-click menu on the local SNMP device) to create a MIB. See 'About locally generated MIBs' on page 3-17 to 3-21 of the Niagara Ax 3.5 SNMP Driver Guide.
