| ... | - **[Cfg] DUT configuration:** DUT1 is configured with IPv4 routing \

| ... | IPv4 /24 route entries. DUT1 is tested with ${nic_name}.
| ... |
| ... | - **[Ver] TG verification:** TG finds and reports throughput NDR (Non \
| ... | Drop Rate) with zero packet loss tolerance and throughput PDR \
| ... | (Partial Drop Rate) with non-zero packet loss tolerance (LT) \
| ... | expressed in percentage of packets transmitted. NDR and PDR are \
| ... | discovered for different Ethernet L2 frame sizes using MLRsearch \
| ... | library.
| ... | Test packets are generated by TG on links to DUT1. TG traffic profile \
| ... | contains two L3 flow-groups (flow-group per direction, 1 flow 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.
| ... |
| ... | - **[Ref] Applicable standard specifications:** RFC2544, RFC791, \
| ... | RFC768 and RFC8926.
