| ... | *[Top] Network Topologies:* TG-DUT1-TG 2-node circular topology\
| ... | with single links between nodes.
| ... | *[Enc] Packet Encapsulations:* Dot1q-IPv4 for L2 switching of IPv4. \
| ... | IEEE 802.1Q tagging is applied on both links TG-DUT1 .
| ... | *[Cfg] DUT configuration:* DUT1 is configured with:\
| ... | 2 VLAN subinterfaces (VID 100 and 200),\
| ... | 1 L2 BD with the 2 VLAN subinterfaces and a BVI,\
| ... | 1 GBP L3 RD,\
| ... | 1 GBP L2 BD with the L2 BD,\
| ... | 1 GBP EPG EPG-1 with sclass 100, the GBP L2 BD and L3 RD,\
| ... | 2 GBP external EP in EPG-1,\
| ... | 2 external subnets with sclass 200 and 300,\
| ... | Contracts allowing full communications between the 2 external subnets.\
| ... | DUT1 tested with ${nic_name} with VF enabled.
| ... | *[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 DUT. TG traffic profile contains two L3 flow-groups\
| ... | (flow-group per direction, 254 flows per flow-group) with all packets\
| ... | containing Ethernet header including IEEE 802.1Q tagging, 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.
