Release Features(s)

  • Ixia-C, Ixia Chassis & Appliances(Novus, AresOne): Support added for GUEv1 IPv4/v6 over UDP traffic.

        f1Ip1 := f1.Packet().Add().Ipv4()​
    f1Ip1.Src().SetValue("1.1.1.1")​
    f1Ip1.Dst().SetValue("1.1.1.2")​
    ​
    f1Udp := f1.Packet().Add().Udp()​
    f1Udp.SrcPort().SetValue(30000)​
    f1Udp.DstPort().SetValue(6080)​
    // IPv4 Over UDP​
    f1Ip2 := f1.Packet().Add().Ipv4()​
    f1Ip2.Src().SetValues([]string{​
        "2.2.2.1",​
        "2.2.2.2",​
        "2.2.2.3",​
        "2.2.2.4",​
    })​
    f1Ip2.Dst().SetValue("3.3.3.1")​

  • Ixia-C, Ixia Chassis & Appliances(Novus, AresOne): Support added for MPLS Over UDP traffic.

        //udp Dst port as 6635​
    f1Udp := f1.Packet().Add().Udp()​
    f1Udp.DstPort().SetValue(6635)​
    f1Udp.SrcPort().SetValue(65530)​
    //mpls over udp​
    f1Mpls1 := f1.Packet().Add().Mpls()​
    f1Mpls1.Label().SetValue(10001)​
    f1Mpls1.BottomOfStack().SetValue(0)
    f1Mpls2 := f1.Packet().Add().Mpls()​
    f1Mpls2.Label().SetValue(10011)​
    //ipv4 over mpls over udp​
    f1MplsIp := f1.Packet().Add().Ipv4()​
    f1MplsIp.Dst().SetValues([]string{​
        "20.20.20.1",​
        "20.20.20.2",​
        "20.20.20.3",​
        "20.20.20.4",​
    })​
    f1MplsIp.Src().SetValue("10.10.10.1")

    Note: MPLS Over UDP with DTLS is not supported.

  • Ixia-C, Ixia Chassis & Appliances(Novus, AresOne): Egress tracking is now supported for UDP, TCP(src/dst port fields), MPLS and IPv4/v6 inner header fields when encapsulated inside UDP/TCP.

        //egress tracking
    f1.EgressPacket().Add().Ethernet()
    f1.EgressPacket().Add().Ipv4()
    f1.EgressPacket().Add().Udp()
    f1.EgressPacket().Add().Mpls()
    mplsLabelTracking := f1.EgressPacket().Add().Mpls()
    tr1 := mplsLabelTracking.Label().MetricTags().Add()
    tr1.SetName("MplsLabelEgressTracking")
    tr1.SetOffset(17)
    tr1.SetLength(3)

Bug Fix(s)

  • Ixia Chassis & Appliances(Novus, AresOne): Issue is fixed where configs with RSVP and multiple Loopback interfaces was throwing error similar to "loopback p2.d2.lo and lo.d not compatible" on set_config.
  • Ixia-C, Ixia Chassis & Appliances(Novus, AresOne): Issue where config with large number of route ranges was causing error similar to "grpc: received message larger than max (114278270 vs. 104857600)" on set_config is fixed by increasing the default gRPC receive buffer size to 1GB.
    • Note that for Ixia Chassis & Appliances(Novus, AresOne) the buffer can now be controlled by setting the environment variable of keng-controller as given below. 
          command:
        ...
        - "--grpc-max-msg-size"​
        - "500"
  • Ixia Chassis & Appliances(Novus, AresOne): Issue is fixed where set_config was throwing error if Traffic Engineering was enabled for ISIS interface, but Priority BandWidths were not explicitly specified.
  • Ixia-C, UHD400: Issue is fixed where DHCPv4 was intermittently crashing on stop.
  • Ixia Chassis & Appliances(Novus, AresOne): Issue is fixed where OSPFv2 Router Ids were not getting set properly when multiple OSPFv2 Routers were configured on a port.

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.
