5.3.1. 1n1l-10ge2p1x710-eth-l2bdscale1mmaclrn-tg-ndrpdr suite

RFC2544: Pkt throughput for cross connected NICs with IPv4 traffic profile. *[Top] Network Topologies: TG-TG 1-node circular topologywith single link between. [Enc] Packet Encapsulations: Eth-IPv4 for L1 cross connect patch. [Ver] TG verification: TG finds and reports throughput NDR (Non DropRate) with zero packet loss tolerance and throughput PDR (Partial DropRate) with non-zero packet loss tolerance (LT) expressed in percentageof packets transmitted. NDR and PDR are discovered for differentEthernet L2 frame sizes using MLRsearch library.Test packets are generated by TG on links to TG.TG traffic profile contains two L3 flow-groups (flow-group perdirection, 500k flows per flow-group) with all packets containingEthernet header, IPv4 header with IP protocol=61 and static payload.MAC addresses ranges are incremented as follows: port01_src ca:fe:00:00:00:00 - port01_src ca:fe:00:07:a1:1f, port01_dst fa:ce:00:00:00:00 - port01_dst fa:ce:00:07:a1:1f, port02_src fa:ce:00:00:00:00 - port02_src fa:ce:00:07:a1:1f, port02_dst ca:fe:00:00:00:00 - port02_dst ca:fe:00:07:a1:1f [Ref] Applicable standard specifications: RFC2544.

5.3.1.1. Local Template

[Cfg] TG runs L1 cross connect config. [Ver] Measure NDR and PDR values using MLRsearch algorithm.Arguments: - frame_size - Framesize in Bytes in integer or string (IMIX_v4_1). Type: integer, string

Set Test Variable  \${frame_size}
Given Set Max Rate And Jumbo
 Then Find NDR and PDR intervals using optimized search
