- Do you also save the configuration to startup-config after configuring snmpv3 ?

- This is a possible culprit : https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvt63576 . for a complete list of known issues with snmpv3 on the 3650 check , https://bst.cloudapps.cisco.com/bugsearch?pf=prdNm&kw=snmpv3&bt=custV&sb=anfr&prdNam=Cisco%20Catalyst%203650%20Series%20Switches , you may need to wait a few seconds when using that link before the bug list is presented. In the context of the two issues mentioned above check current software version being used and upgrade to the advisory release if applicable https://software.cisco.com/download/home/286309910/type/282046477/release/Gibraltar-16.12.5b , check if the problem remains after that.
