  ┌────────────────────────────────────────┤ BandwidthD ├────────────────────────────────────────┐
  │ Bandwidthd needs to know which interface it should listen for traffic on. Only a single      │
  │ interface can be specified. If you want to listen on all interfaces you should specify the   │
  │ metainterface "any". Running "bandwidthd -l" will list available interfaces.                 │
  │                                                                                              │

 │ Bandwidthd can create graphs for one or several ip-subnets. Subnets are specified either in   │
 │ dotted-quad format (192.168.0.0 255.255.0.0) or in CIDR format (192.168.0.0/16) and           │
 │ separated by a comma. Example: 192.168.0.0/16, 10.0.0.0 255.0.0.0, 172.16.1.0/24. If you      │
 │ don't know what to specify then you can use 0.0.0.0/0 but it is strongly discouraged.         │
