unsupported config version

[Felipe Oliveira do Rosario]

Hi everyone, I'm trying to use generator.yaml for Juniper or Fortigate and with version 3 I'm getting the following error:

ts=2023-07-17T18:14:53.048Z caller=main.go:136 level=error msg="Error generating config netsnmp" err="unsupported config version"

Honestly, I don't know where I'm going wrong, I would like your help because with this same configuration using version 2 I can generate the snmp.yaml as expected for both Juniper and Fortigate, Cisco, etc, but for security reasons I need to use snmpv3, and when I try to use it I always get the same error.. can you please help me? Follow my example file!
At first I thought it was the indentation, but it's not because with versions 1 and 2 it works normally.

Note: Remembering that all my devices already have snmp enabled!

Config version is a top level key for the new generator/exporter config formats. It's unrelated to SNMP protocol versions.

Hi Ben, i don't know if i understood well, you can explain for me please? Where i localize the config version ? What i need to do for use the snmpv3 correctly ? 

[Brian Candler]

You simply copy-paste what Ben showed.  To extend it slightly for clarity:

version: 2

auths:
  prod_router:
    version: 3
    security_level: authPriv
    username: admin
    auth_protocol: SHA
    password: tcpip123
    priv_protocol: AES
    priv_password: xyzzy

modules:

  ....

"version: 2" at the top of the file, refers to the config file version.  This is version 2 of the config file: that is, the new format which has separate "modules" and "auths" sections.

Under "auths", and below a named auth section like "prod_router" in the example above, "version: 3" refers to the SNMP version.
