6.10.1. 2n1l-10ge2p1x710-ethip4-l2patch-scapy suite

L2 cross-connect test cases

  • [Top] Network Topologies: TG-DUT1-TG 2-node circular topology with single links between nodes.

  • [Enc] Packet Encapsulations: Eth-IPv4 for L2 switching of IPv4. Both apply to all links.

  • [Cfg] DUT configuration: DUT1 is configured with L2 patch switching.

  • [Ver] TG verification: Test IPv4 packets with IP protocol=61 are sent in both directions by TG on links to DUT1; on receive TG. verifies packets for correctness and their IPv4 src-addr, dst-addr and MAC addresses.

  • [Ref] Applicable standard specifications: RFC792

6.10.1.1. Local Template

  • [Ver] Make TG send IPv4 packets in both directions between two of its interfaces to be switched by DUT to and from docker; verify all packets are received.

Arguments: - frame_size - Framesize in Bytes in integer. Type: integer - phy_cores - Number of physical cores. Type: integer - rxq - Number of RX queues, default value: ${None}. Type: integer


Set Test Variable  \${frame_size}
Given Set Max Rate And Jumbo
  And Add worker threads to all DUTs  ${phy_cores}  ${rxq}
  And Pre-initialize layer driver  ${nic_driver}
  And Apply startup configuration on all VPP DUTs  with_trace=${True}
 When Initialize layer driver  ${nic_driver}
  And Initialize layer interface
  And Initialize L2 patch
 Then Send IPv4 bidirectionally and verify received packets  ${tg}  ${TG_pf1}[0]  ${TG_pf2}[0]
