Any Windows based SNMPv3 walk/query tools that don't cost money?

I need to create some custom pollers but I need to find the right OIDs first.

Isn't there a SNMP walk / OID query tool that allows you to use SNMPv3 without having to pay for something?
I tried all these with the help of ChatGPT. Nothing.

1. Paessler SNMP Tester
A free GUI-based SNMP tool that supports SNMPv3.
Result: Failed to query the router due to engine ID and authentication issues.

2. SNMPv3 PowerShell Module
A PowerShell module specifically designed for SNMPv3 operations.
Result: Installed successfully, but failed to query the router (request timeouts and authentication errors).

3. SnmpSharpNet PowerShell Package
An open-source .NET-based SNMP library with PowerShell integration.
Result: Installed successfully but did not support SNMPv3 USM (User-based Security Model) features as expected.

4. Proxx.SNMP PowerShell Module
A PowerShell module for SNMP operations, including SNMPv3.
Result: Installed successfully but lacked proper SNMPv3 support for authentication and encryption.

5. iReasoning MIB Browser (Free Version)
A popular GUI-based SNMP browser with SNMPv3 support in the professional version.
Result: The free version did not support configuring SNMPv3 USM users, so it couldn’t be used for SNMPv3 queries with authentication and encryption.

6. SnmpB
An open-source GUI-based SNMP browser that supports SNMPv3.
Result: Installed successfully, but the expected SNMPv3 configuration options (adding users) were not available in the version you downloaded.

There is a snmpwalk utility that comes with the SolarWinds Platform. It dumps the SNMP walk details into a text file.

Thanks Chad, I'll give that a try!

You can use powershell as well

$WalkRequest = @{
    UserName    = 'SNMPUSER'
    Target      = '10.47.99.125'
    OID         = '1.3.6.1.4.1.9.9.473.1.1.2'
    AuthType    = 'SHA1'
    AuthSecret  = 'WIb#dwnsoleELD3hdn'
    PrivType    = 'AES256'
    PrivSecret  = 'WIb#dwnsoleELD3hdn'
}

Invoke-SNMPv3Walk @WalkRequest | Format-Table -AutoSize

Unfortunately I discovered that there IS NO OID that gives me the information that I want, which is the number of active, dynamic NAT translations. Seems strange that there is no OID for this. It's a very valuable piece of information to know, for us, anyway.

That snmp walk utility works, chad. I'm marking this as a solution, even though I discovered there is no OID that gives me the information I want (see my response to bobmarley below)

I also use the tool @chad.every mentioned which is on the Solarwinds Server itself. There is also a couple of them in the Solarwinds Engineers Toolset which work well. The toolset is relatively inexpensive and has a number of good tools in it.

The session table should have the info, you just need to parse it from their.

I've long used the Paessler SNMP Tester tool for testing.

It even comes in a portable format so you don't have to install it.
