◆ 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
vmvlib_main_t corresponding to the current thread.
nodevlib_node_runtime_t data for this node.
framevlib_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().
