Import cpe rouetr

Hi support
we managed to import customers into splynx from a csv file. In our case we use static address for our customers. A customer may have several sites so several router CPE. We have just installed Splynx and we have some concerns to know:
1 we want to use radius so that our customers authenticate in order to have internet
2 how to import if possible the list of CPE router in router or it will be done manually
3 how to configure the community snmp ours is version 2
