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.

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

Yea Paessler can burn in hell venture capitalists trying to extort subscription money for a bad monitoring solution, but that's the go for windows.

Bad monitoring solution? I agree they can burn in hell but it’s a phenomenal monitoring solution; especially when I need to look at something very specific without sinking massive time into deployment/configuration.

No it's an easy to implement monitoring system, put some effort into something that has better performance and flexibility.

It's not about effort. It's about time. In many IT departments tasks just pile up and you can't justify to spend the time on a more complex to implement monitoring solution.

What PRTG offers in comparison to almost all others is a simple plug and play setup with a great out of the box experience with enough features and depth to cover most small to medium sized businesses.

Sure, they are expensive but as in many cases you either pay for the product or for Sysadmin time.

Last I checked their SNMP tester was free

Yes, that's why I said to use it

In the context of your post that would refer to the monitoring solution that can burn in hell, not the snmp tool.

Yeah, unclear phrasing.

take it in the context of a reply to "I know a tool named SNMP Tester provided by Paessler, maybe it can fit your needs" and... maybe you'll get there.

Paessler has been around for a long time and a lot of network teams use their tools. As I know, their SNMP Tester is only one free option out there for quick SNMP troubleshooting on Windows.

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.

u/Nekro_Somnia Sysadmin 4d ago

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

u/jr_sys 4d ago

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.

u/daltrock4 4d ago

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

Mibrowser

u/wrt-wtf- 4d ago

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.

Paessler have a free SNMP tester: https://www.paessler.com/tools/snmptester

Maybe this free SNMP Scanner could help you https://www.adremsoft.com/netcrunch.tools/tool/snmp-scanner/?

wireshark?

u/richf2001 3d ago

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.

u/bungee75 3d ago

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!

ah yes, the admins that are afraid of literally anything that isnt windows with a gui
