Release Features(s)

  • Keng-Operator: go version is upgraded to use v1.23 along with security updates.

  • Ixia-C: Support added to send flows over DHCPv4 endpoints.

      f1 := config.Flows().Add()​
  f1.SetName(flowName).​
    TxRx().Device().​
    SetTxNames([]string{"p1d1dhcpv4_1"}).​
    SetRxNames([]string{"p2d1ipv4"})​
  f1Ip := f1.Packet().Add().Ipv4()​
  // will be populated automatically with the the dynamically allocated Ip to DHCP client​
  f1Ip.Src().Auto().Dhcp()​
  …​
  f2Ip.Dst().Auto().Dhcp()​

  • Ixia Chassis & Appliances(Novus, AresOne): Support added for LLDP.

      // LLDP configuration.​
  lldp := config.Lldp().Add()​
  lldp.SystemName().SetValue(lldpSrc.systemName)​
  lldp.SetName(lldpSrc.otgName)​
  lldp.Connection().SetPortName(portName)​
  lldp.ChassisId().MacAddressSubtype().​
    SetValue(lldpSrc.macAddress)​

Bug Fix(s)

  • Ixia Chassis & Appliances(Novus, AresOne): There was degradation in time taken for starting large number of BGP/BGP+ peers on one port. This issue is fixed.​

  • Ixia Chassis & Appliances(Novus, AresOne): There was an exception being returned from set_config on creating multiple loopbacks in a device and configuring protocols on top of that. This issue is fixed.

  • Ixia Chassis & Appliances(Novus, AresOne): If multiple routes are received by a BGP/BGP+ peer with some having MED/Local Preference and some not having MED/Local Preference, in get_states MED/Local Preference were not being correctly returned. This issue 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.
  • 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.
