8.2.9. L2XC Ethernet Switching

8.2.9.1. eth2p-eth-l2xcbase-eth-2vhost-1vm-func

L2 cross-connect test cases

  • [Top] Network Topologies: TG=DUT=VM 3-node topology with VM and double parallel links.
  • [Enc] Packet Encapsulations: Eth-IPv4-ICMPv4 for L2 switching of IPv4; Eth-IPv6-ICMPv6 for L2 switching of IPv6 use. Both apply to all links.
  • [Cfg] DUT configuration: DUT1 is configured with L2 cross-connect (L2XC) switching.
  • [Ver] TG verification: Test ICMPv4 (or ICMPv6) Echo Request packets are sent in both directions by TG on links to DUT1 via VM; on receive TG verifies packets for correctness and their IPv4 (IPv6) src-addr, dst-addr and MAC addresses.

L2 cross-connect test cases

  • [Top] Network Topologies: TG-DUT1-DUT2-TG 3-node circular topology with single links between nodes.
  • [Enc] Packet Encapsulations: Eth-IPv4-ICMPv4 for L2 switching of IPv4; Eth-IPv6-ICMPv6 for L2 switching of IPv6 use. Both apply to all links.
  • [Cfg] DUT configuration: DUT1 and DUT2 are configured with L2 cross-connect (L2XC) switching.
