| ... | *[Enc] Packet Encapsulations:* Eth-IPv4 for L2 switching of IPv4.
| ... | *[Cfg] DUT configuration:* DUT1 and DUT2 are configured with L2 bridge-\
| ... | domain and MAC learning enabled. DUT1 and DUT2 tested with 2p10GE NIC
| ... | X710 by Intel.
| ... | *[Ver] TG verification:* TG finds and reports throughput NDR (Non Drop\
| ... | Rate) with zero packet loss tolerance or 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 either binary search or linear search\
| ... | algorithms with configured starting rate and final step that determines\
| ... | throughput measurement resolution. Test packets are generated by TG on\
| ... | links to DUTs. TG traffic profile contains two L3 flow-groups\
| ... | (flow-group per direction, 253 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.
| ... | *[Ref] Applicable standard specifications:* RFC2544.
