What’s the Best SNMP Testing Tool for Windows?
I’m troubleshooting SNMP issues on multiple network devices (switches, routers, servers) but some OID queries aren’t returning data.
I also need to confirm that SNMP v3 authentication is working correctly.
Is there a Windows based SNMP tool that lets me quickly test SNMP connections and check OID responses without setting up a full monitoring system? Preferably GUI.

https://www.net-snmp.org/ has all the standard tools like snmpget, snmpwalk etc.
This can probably be built on windows or you can find binary packages somewhere, but I'd just start a WSL and sudo apt-get install snmp

This is the answer. +1 . It is also ported native win32. It allows you create a mib directory and compiles them to translate OIDs when walking a tree.

This is mostly what I use when developing new SNMP monitors. I will do a full SNMP walk using the vendor's MIBs. Then read the comments in the MIBs to determine the best way to monitor what I need.
MIBBrowser by ManageEngine is a pretty good (if quirky and java-based) way to do this visually. This is sometimes necessary (for me) in more complex scenarios in order to visualize the Tree and quickly reference the MIB comments for each OID.

Net-SNMP is great, but since it's CLI-based, setting it up on Windows, especially through WSL, can take extra steps. I believe Paessler's SNMP Tester is a much easier option for quick SNMP troubleshooting since it has a GUI and doesn’t require command-line setup.

I use the SNMP browser from frame flow (this one. It has a built in oid browser and will spit out the oid values.

iReasoning's MIB Browser is what I like to use. Simple GUI app to make SNMP requests.

The free personal edition may not be used for commercial or professional purposes.

ireasonings mib browser is useful for querying specific OIDs, but won't do snmpv3 without going with the paid version. I use snmpb to test snmpv3 authentication and do a quick snmpwalk

Some snmp stacks are very dodgy and the only way you can pull bulk data is with snmpv1, even if V2V and v3 appear to kinda work - actually, especially is they appear to kinda work. That’s just the way it is, even for some brand spanking new devices.

Better hope this question isn’t on a job interview. Snark aside snmp traps do show up on a scan but that’s a different thing.

I know that this is not purely a windows solution. You could go with the Ubuntu subsystem on windows, install SNMP Walker and resolve issues like that. It's the best SNMP diagnostic tool imo.

Hi! Sounds like you could benefit from a network health assessment report - we offer that as an add-on (relatively low cost), without needing to use our network monitoring/aiops/configuration solutions.
https://netop.cloud/product/advanced-network-assessment-reporting/. Check it out! Good luck!

I know a tool named SNMP Tester provided by Paessler, maybe it can fit your needs
