IPFIX sampled data not being sent over when the collector is connected over fxp0 interface.

IPFIX sampled data not being sent over when the collector is connected over fxp0 interface even when the configuration is correct.

Flow records and templates cannot be exported if the flow collector is reachable through any management interface, this is because with IPFIX the sampling process is done at the FPC level, while the fpx0 is a interface located on the Routing Engine, sending sample data to the RE could cause CPU resources to get exhausted.

Solution is to change the collector to be reachable over regular forwarding interface.
