Release Features(s)

  • Ixia Chassis & Appliances(Novus, AresOne): Support added for DHCPv6 client interfaces to be used as source/destination for device traffic.

    • In this the learned IPv6 address from the DHCPv6 server is automatically populated in ipv6.src/dst if the choice is set to auto.dhcp.
      clientToServerFlow.SetName("ClientToServer").TxRx().Device().
  SetTxNames([]string{"DHCPv6ClientName"}).
  SetRxNames([]string{"DHCPv6ServerInterfaceName"})
  clientToServerFlow.Packet().Add().Ethernet()
  clientToServerFlowIp := clientToServerFlow.Packet().Add().Ipv6()
  clientToServerFlowIp.Src().Auto().Dhcp()
  
  serverToClientFlow.SetName("ServerToClient").TxRx().Device().
      SetTxNames([]string{"DHCPv6ServerInterfaceName"}).
      SetRxNames([]string{"DHCPv6ClientName"})
  serverToClientFlow.Packet().Add().Ethernet()
  serverToClientFlowIp := serverToClientFlow.Packet().Add().Ipv6()
  serverToClientFlowIp.Dst().Auto().Dhcp()

    Note: For DHCPv6 client to DHCPv6 server each flow supports only one source endpoint in tx_rx.device.tx_names, hence a separate flow has to be configured for each DHCPv6 client if packet[i].ipv6.src.auto.dhcp is set.

  • Ixia Chassis & Appliances(Novus, AresOne): Support added for devices[i].ethernets[j].dhcpv6_interfaces[k].options/options_request and devices[i].dhcp_server.ipv6_interfaces[j].options.

          // Configure a DHCPv6 Client
      dhcpv6Client := d1Eth1.Dhcpv6Interfaces().Add().
        SetName("DHCPv6-Client")
      
      .........

      //options
      dhcpv6Client.Options().VendorInfo().
        SetEnterpriseNumber(1000).
        OptionData().
        Add().
        SetCode(88).
        SetData("enterprise")
      dhcpv6Client.Options().VendorInfo().AssociatedDhcpMessages().All()

      //option request
      dhcpv6Client.OptionsRequest().Request().Add().BootfileUrl()
      dhcpv6Client.OptionsRequest().Request().Add().Custom().SetType(3)
      dhcpv6Client.OptionsRequest().AssociatedDhcpMessages().All()

      // Configure a DHCPv6 Server
      dhcpv6Server := d2.DhcpServer().Ipv6Interfaces().Add().
        SetName("DHCPv6-Server")

      ............
      dhcpv6Server.Options().BootfileUrl().SetUrl("URL").AssociatedDhcpMessages().All()
        dhcpv6Server.Options().Dns().SetPrimary("8::8").SecondaryDns().Add().SetIp("9::9")

  • Ixia Chassis & Appliances(Novus, AresOne): Support added for devices[i].dhcp_server.ipv6_interfaces[j].leases[k].ia_type.choice.iapd/ianapd.

          // Configure a DHCPv6 Server
      dhcpv6Server := d2.DhcpServer().Ipv6Interfaces().Add().
        SetName("DHCPv6-Server")

      dhcpv6ServerPool := dhcpv6Server.SetIpv6Name("p2d1ipv6").
        Leases().Add().
        SetLeaseTime(3600)
      IaType := dhcpv6ServerPool.IaType().Iapd()
      IaType.
        SetAdvertisedPrefixLen(64).
        SetStartPrefixAddress("2000:0:0:100::0").
        SetPrefixStep(1).
        SetPrefixSize(10)

  • Ixia-c: Support added for sending Organizational tlvs in LLDP PDUs.

      lldp := config.Lldp().Items()[0]

  orgInfos1 := lldp.OrgInfos().Add()
  orgInfos1.Information().SetInfo("AABB11")
  orgInfos1.SetOui("1abcdf").SetSubtype(1)

    Note: Received Organizational tlvs can be seen in the get_states response of lldp_neighbors.

Known Issues

  • Ixia Chassis & Appliances(Novus, AresOne): If keng-layer23-hw-server version is upgraded/downgraded, the ports which will be used from this container must be rebooted once before running the tests.
  • Ixia Chassis & Appliances(Novus, AresOne): StartProtocols/set_control_state.protocol.all.start can get stuck till the time all DHPCv4/v6 clients receive the leased IPv4/v6 addresses from the DHCPv4/v6 server/relay agent. This may result in getting "context deadline exceeded" error in the test program.
  • UHD400: Packets will not be transmitted if flows[i].rate.pps is less than 50.
  • UHD400: values for fields in flow packet headers can be created with maximum length of 1000 values.
  • Ixia-C: Flow Tx is incremented for flow with tx endpoints as LAG, even if no packets are sent on the wire when all active links of the LAG are down.
  • Ixia-C: Supported value for flows[i].metrics.latency.mode is cut_through.
  • Ixia-C: The metric loss in flow metrics is currently not supported.
  • Ixia-C: When flow transmit is started, transmission will be restarted on any existing flows already transmitting packets.
