Also - another question which is unclear from the documentation: When using the generator.yml file to generate snmp.yml, are the values "password" and "priv_password" entered as plaintext in the generator.yml config file or do they need to be encrypted already with their given "auth_protocol" and "priv_protocol"? I had assumed that you give the passwords in plaintext and the generator would use the given algorithm to encrypt them.
