Release Features(s)

  • gosnappi: gosnappi is updated to work with go >= v1.21.

    • Older versions of go are no longer supported.
      • When older version of go is installed on the server, User will be liable to get errors like "slices: package slices is not in GOROOT (/root/.local/go/src/slices)".

    Note: keng-controller and otg-gnmi-server are upgraded to use go v1.23.

  • 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)​
    }​

  • Ixia Chassis & Appliances(Novus, AresOne): Support added to update traffic rate on the fly.

      req := gosnappi.NewConfigUpdate()
  reqFlow := req.Flows().SetPropertyNames([]gosnappi.FlowsUpdatePropertyNamesEnum{
    gosnappi.FlowsUpdatePropertyNames.RATE,
  })
  f1.Rate().SetPps(100) // f1 is an existing flow in the config
  reqFlow.Flows().Append(f1)
    gosnappi.NewApi().UpdateConfig(req)

Bug Fix(s)

  • UHD400: Issue where flows[i].packet.ipv6.dst.increment was not being reflected in transmitted packets when two or more flows were configured, is now 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.
