Role paramaters

• softflowd_host (mandatory) - The host where accounting datagrams are to be sent to. The host may be specified using a hostname or using a numeric IPv4 or IPv6 address. Numeric IPv6 addresses should be encosed in square brackets to avoid ambiguity between the address and the port.
• softflowd_port (mandatory) - The port at the host where accounting datagrams are to be sent to. The destination port may be a portname listed in services(5) or a numeric port.
• softflowd_interface - Specify a network interface on which to listen for traffic or any to listen on every interface. (default any)
• softflowd_max_flows - Specify the maximum number of flows to concurrently track. (default 8192)
• softflowd_timeout - List of strings of format timeout_name=time. More at softflowd(8).
• softflowd_hoplimit - Set the IPv4 TTL or the IPv6 hop limit to hoplimit otherwise default system TTL.
• softflowd_track_level - Specify which flow elements softflowd should be used to define a flow. track_level may be one of:
  • full - track everything in the flow (the default).
  • proto - track source and destination addresses and protocol.
