Bug Fix(s)

Ixia Chassis & Appliances(Novus, AresOne): Issue is fixed where on running a test with a large number of replay_updates multiple times would cause a PCPU out of memory crash, resulting in "context deadline" error on set_config or set_control_state.protocol.start.

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: Non default virtual wiring configuration can result in ARP failures and traffic loss due to dropped packets on the rx path.
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. If larger set of values are required for a field which are random, please use random instead of 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.

  })

  configUpdate = gosnappi.NewConfigUpdate()
  configUpdate.SetFlows(flowUpdateCfg)
  res, err := client.Api().UpdateConfig(configUpdate)

Bug Fix(s)

Ixia-C: Issue where flows containing ipv4/v6 header without src/dst specified was returning error on set_config "Error flow [ flow-name ] has AUTO IPv4 src address and Tx device [ flow-end-point ] with no dhcpv4 interface" is fixed.

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. If larger set of values are required for a field which are random, please use random instead of 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.

Ixia-C, Ixia Chassis & Appliances(Novus, AresOne), UHD400: Support added for BGP GracefulRestart Notification Enhancement based on RFC8538.

To enable advertisement of Notification support in GracefulRestart capability:

    peer.GracefulRestart().SetEnableNotification(true)

To optionally send Notification when peer is going down during InitiateGracefulRestart trigger:

    grAction := gosnappi.NewControlAction()
    bgpPeersRestart := grAction.Protocol().Bgp().InitiateGracefulRestart()
    bgpPeersRestart.
        SetPeerNames([]string{"peer1"}).
        SetRestartDelay(20)
    notification:= bgpPeersRestart.Notification()
    if sendHardReset == true {              	
      notification.Cease().SetSubcode(
        gosnappi.DeviceBgpCeaseErrorSubcode.HARD_RESET_CODE6_SUBCODE9)
    } 
    else {
      /* Send anything else except hard reset */ 
      notification.Cease().SetSubcode(
          gosnappi.DeviceBgpCeaseErrorSubcode.OUT_OF_RESOURCES_CODE6_SUBCODE8)
    }

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")

        SetEnterpriseNumber(1000).
        OptionData().
        Add().
        SetCode(88).
        SetData("enterprise")

      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)
