running_config
string
This option is used only with state parsed.
The value of this option should be the output received from the VyOS device by executing the command show configuration commands | match 'nat'.
The state parsed reads the configuration from show configuration commands | match 'nat' and transforms it into Ansible structured data as per the module argspec. The value is then returned in the parsed key within the result.
The state replaced replaces only the provided configuration, while overridden removes any existing NAT configuration not specified in config.
state
string
    Choices:
  • deleted
  • merged ←
  • overridden
  • replaced
  • gathered
  • rendered
  • parsed
The state the configuration should be left in.
