Release Features(s)

  • Ixia Chassis & Appliances(Novus, AresOne): Support added for OSPFv2. details

      ospfRouter := device1.Ospfv2().​
          SetName("OspfRtr").​
          SetStoreLsa(true)​

  intf := ospfRouter.Interfaces().Add().​
                  SetName("OspfIntf").​
                  SetIpv4Name("Ipv4Intf1")​

  intf.Area().SetId(0)​
  intf.NetworkType().PointToPoint()​
  ospfRoutes := ospfRouter.V4Routes().​
                          Add().​
                          SetName("OspfRoutes")​
  ospfRoutes.​
          Addresses().​
          Add().​
          SetAddress("10.10.10.0").​
          SetPrefix(24).​
          SetCount(100).​
          SetStep(2)​​
    • Learned LSAs can be fetched by the following
      req := gosnappi.NewStatesRequest()​
  req.Ospfv2Lsas().SetRouterNames(routerNames)​
  res, err := client.GetStates(req)
    • OSPFv2 metrics can be fetched by the following
      req := gosnappi.NewMetricsRequest()
  reqOspf := req.Ospfv2()
  reqOspf.SetRouterNames(routerNames)

  • Ixia-C, Ixia Chassis & Appliances(Novus, AresOne): Support added to update flows[i].size and flows[i].rate on the fly.

      ​
  flow = get_config.Flows().Items()[0]​
  flow.Rate().SetPps(120)​
  flow.Size().SetFixed(512)​

  flowUpdateCfg: = gosnappi.NewConfigUpdate().Flows()
  flowUpdateCfg.Flows().Append(flow)​
  flowUpdateCfg.SetPropertyNames ([]gosnappi.FlowsUpdatePropertyNamesEnum{​
    gosnappi.FlowsUpdatePropertyNames.SIZE, gosnappi.FlowsUpdatePropertyNames.RATE
  })​

  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.
