| ... |
| ... | - **[Enc] Packet Encapsulations:** Eth-IPv4 for L2 bridge domain.
| ... |
| ... | - **[Cfg] DUT configuration:** DUT1 is configured with two L2 bridge \
| ... | domains and MAC learning enabled. DUT1 is tested with ${nic_name}. \
| ... | Container is connected to VPP via Memif interface. Container is \
| ... | running same VPP version as running on DUT. Container is limited via \
| ... | cgroup to use cores allocated from pool of isolated CPUs. There are \
| ... | no memory contraints.
| ... |
| ... | - **[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 DUTs. TG traffic profile \
| ... | contains two L3 flow-groups (flow-group per direction, 254 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.
