The InterfaceState command is used to change Neblina's interface streaming capabilities. By default, Neblina will respond to a command only on the same interface it was sent, regardless of the state of the interface. On the other hand, Neblina streaming packets are sent to all enabled interfaces. If all interfaces are disabled, Neblina will not stream any packets.


This command uses the Command-Ack protocol.
