ipfix_collector_node_fn()

uword ipfix_collector_node_fn	(	vlib_main_t *	vm,
		vlib_node_runtime_t *	node,
		vlib_frame_t *	from_frame
	)

Node to receive IP-Fix packets.

Node Identifier:

ipfix-collector

This function receives IP-FIX packets and forwards them to other graph nodes based on SetID field in IP-FIX.

Parameters

vm	vlib_main_t corresponding to the current thread.
node	vlib_node_runtime_t data for this node.
frame	vlib_frame_t whose contents should be dispatched.

Graph mechanics: buffer, next index usage

Uses:

• vlib_buffer_get_current(p0)
  • Parses IP-Fix packet to extract SetId which will be used to decide next node where packets should be enqueued.

Next Index:

• Dispatches the packet to other VPP graph nodes based on their registartion for the IP-Fix SetId using API ipfix_collector_reg_setid().
