Meraki SNMP v3; how do you set this up?

I have tried the SNMP Walk application and testing connectivity to my Meraki devices over SNMP v3 to no avail.  Has this been addressed or additional instructions available for setting these devices up in Solar Winds?  I hate to have to monitor them within the meraki cloud when I have NPM, Topology mapper and had considered NCM but without the SNMP v3 capabilities, will probably pull these out of Solar Winds Monitoring based on the False positive errors I get.  Is there another set of documents that specifically addresses SNMP v3 and Meraki?  I've looked through THWACK and only found 2 articles which do not really apply.
