Solution
NI does not currently distribute any library or toolkit that specifically address the SNMP protocol, and none of the NI Real-Time controllers ship with a built-in implementation of the SNMP. However, alternative approaches are available.
Linux Real-Time Controllers
- For NI Linux Real-Time controllers, there are SNMP tools available via the OPKG package manager. These packages can be located using an OPKG list command and text match for "snmp". Use the following command as a reference: opkg list | grep -i snmp.
LabVIEW
- It is possible to build SNMP functionality in LabVIEW using TCP/IP VIs that implement the SNMP protocol.
- Additionally, Viodia (an NI Partner) offers an SNMP Toolkit for LabVIEW. Visit their website (External Viodia Site: SNMP Toolkit for LabVIEW) for further information.
LabWindows™/CVI™
- LabWindows/CVI applications can interface directly with the Windows SNMP API (WinSNMP), which is included as part of the Windows SDK. To use this API, you must link your project against the appropriate library and include the required headers. For this follow the next steps:
- Go to Edit >> Add Files to Project >> Library (.lib).
- Locate WSnmp32.lib: Navigate to the Windows SDK library folder installed on your system with LabWindows/CVI. Typical paths include:
- For 64-bit version: C:\Program Files (x86)\Windows Kits\8.1\Lib\winv6.3\um\x64.
- For 32-bit version: C:\Program Files (x86)\Windows Kits\8.1\Lib\winv6.3\um\x86.
- Include required header: In your source code, include the following header to access the WinSNMP API: winsnmp.h
- Another option is to use a third-party or custom SNMP library implemented in C. These libraries can provide higher-level abstractions and may offer extended protocol support (for example, SNMPv3), reducing the complexity of working directly with the low-level WinSNMP API.
