Take a look at section 17.15.2 in the ConfD User’s Guide on how the SNMP Agent works in conjunction with the ConfD AAA model. If you have access to the SNMP examples in ConfD Premium, you can look at $CONFD_DIR/examples.confd/snmpa/7-transform (or really any of the SNMP examples) for how to initialize the community and vacm tables with working values.
