DHCPv4 proxy test cases

  • [Top] Network Topologies: TG = DUT with two links between the nodes.
  • [Enc] Packet Encapsulations: Eth-IPv4-UDP-BOOTP-DHCP
  • [Cfg] DUT configuration: DUT is configured with DHCPv4 proxy.
  • [Ver] TG verification: Test DHCPv4 packets are sent on TG on first link to DUT and received on TG on second link. On receive TG verifies if DHCPv4 packets are valid.
