| Documentation | *IPFIX ipv4 test cases*
| ...
| ... | IPFIX tests use 3-node topology TG - DUT1 - DUT2 - TG with
| ... | one link between the nodes. DUT1 is configured with IPv4
| ... | routing and static routes. IPFIX is configured on DUT1 with
| ... | DUT1->TG interface as collector. Test packets are
| ... | sent from TG to DUT1. TG listens for flow report packets
| ... | and verifies that they contains flow record of test packets sent.
