| ... | Rate) with non-zero packet loss tolerance (LT) expressed in percentage\
| ... | of packets transmitted. NDR and PDR are discovered for different\

| ... | Test packets are generated by TG on links to DUT1. TG traffic profile\
| ... | contains 2 randomized L3 flow-groups (flow-group per direction, 100K\
| ... | flows per flow-group) with all packets containing Ethernet header,\
| ... | IPv4 header with IP protocol=61 and static payload. MAC addresses are\
| ... | matching MAC addresses of the TG node interfaces.\
