Switch

sends packet stream to settable output

SYNOPSIS§

Switch([OUTPUT])

Batching: Batching natively supported
Ports: 1 input, any number of outputs
Processing: push

DESCRIPTION§

Switch sends every incoming packet to one of its output ports -- specifically, OUTPUT. The default OUTPUT is zero; negative OUTPUT means to destroy input packets instead of forwarding them. You can change OUTPUT with a write handler. Switch has an unlimited number of outputs.

ELEMENT HANDLERS§

• switch (read/write) — Return or set the OUTPUT parameter.
• CLICK_LLRPC_GET_SWITCH (llrpc) — Argument is a pointer to an integer, in which the Switch's K parameter is stored.
• CLICK_LLRPC_SET_SWITCH (llrpc) — Argument is a pointer to an integer. Sets the K parameter to that integer.
