SNMPv3 supports commercial-grade security, including authentication, authorization, access control, and privacy. Previous versions of the protocol contained well-known security weaknesses that were easily exploited. As such, SNMPv1/2 receivers must be disabled.

From the NSX Manager web interface, go to the System >> Configuration >> Fabric >> Profiles >> Node Profiles.

Click "All NSX Nodes" and view the SNMP Polling and Traps configuration.

From the NSX Manager web interface, go to the System >> Configuration >> Fabric >> Profiles >> Node Profiles.

Click on "All NSX Nodes" and delete and v2c Polling or Trap configurations.
