Release Features(s)

• Support added for link up/down trigger for UHD400​.

    portStateAction := gosnappi.NewControlState().
                          Port().
                          Link().

                          SetState(gosnappi.StatePortLinkState.DOWN)
    gosnappi.NewApi().setControlState(portStateAction)

• Support added for 0x8100(Vlan) and 0x6007(Google Discovery Protocol) ether types in data plane traffic in UHD400.

Bug Fix(s)

• Some tests were failing because packets were not sent on wire due to frame size of flows not being sufficient to include tracking information in Ixia Chassis & Appliances(AresOne only)​ is fixed.
• egress tracking on VLAN id or other fields for more than 3 bits was not working in Ixia Chassis & Appliances(Novus, AresOne)​, is fixed.
  • egress tracking now supports upto 11 bits.
• Issue in ARP resolution in certain cases is now fixed in UHD400​.

Known Issues

• If keng-layer23-hw-server version is upgraded/downgraded, the ports from Ixia Chassis & Appliances(Novus, AresOne) which will be used from this container must be rebooted once before running the tests.
• Adding more than 256 devices on a single ixia-c-port causing failure for Ixia Chassis & Appliances(Novus, AresOne).
• 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.
• With certain DUTs, ssh service hangs if ISIS L1 MD5 is enabled.
• Supported value for flows[i].metrics.latency.mode is cut_through.
• The metric loss in flow metrics is currently not supported.
• When flow transmit is started, transmission will be restarted on any existing flows already transmitting packets.

Release Feature(s)

• Support for deprecated control, action and update APIs (set_transmit_state, set_link_state, set_capture_state, update_flows, set_route_state, send_ping, set_protocol_state, set_device_state) have been removed. Please use following set_control_state, set_control_action and update_config APIs instead of the previous ones. Please refer to go utils and python utils for further details usage.
• Most properties in OTG with integer data type have been assigned correct integer format (from uint32, uint64, int32 and int64). Please click here to examine all changes.
• Once you upgrade the new ixia-c release, in addition to removing the deprecated APIs from the test programs, data types of some variables in the test programs might need to be changed to avoid compilation errors.

Known Issues

• Supported value for flows[i].metrics.latency.mode is cut_through.
• The metric loss in flow metrics is currently not supported.
• When flow transmit is started, transmission will be restarted on any existing flows already transmitting packets.

Release Feature(s)

• Enabling metric_tags for egress tracking is now also supported on ipv6.src/dst, ipv6.traffic_class, ipv6.flow_label and ipv6.payload_length. [Ixia-C]

    eth := flow.EgressPacket().Add().Ethernet()
    ipv6 := flow.EgressPacket().Add().Ipv6()
    ipv6Tag := ipv6.Dst().MetricTags().Add()
    ipv6Tag.SetName("flow_ipv6_dst")
    ipv6Tag.SetOffset(120)
    ipv6Tag.SetLength(8)

• Support is available in gNMI to fetch the drill-down statistics for egress tracking as follows [Ixia-C] details:

    1. Flow level metrics + Tagged Metrics:
        example path: "flows/flow[name=f1]“
    2. Only Flow level metrics:
        example path: "flows/flow[name=f1]/state“
    3. Only Tagged metrics 
        example path: "flows/flow[name=f1]/tagged-metrics“
    4. Filtered Tagged metrics: 
        example path: "flows/flow[name=f1]/tagged-metrics/tagged-metric[name-value-pairs=flow_ipv6_dst=0x2]”
  

Bug Fix(s)

• For flow.duration.continuous type of traffic in Ixia-C, intermittent issue where last few packets in a traffic flow were not accounted for in flow_metrics.frames_rx statistics after stopping a flow is fixed.
• Proper error mesage is propagated to user if user has used community edition of Ixia-C (instead of licensed edition) and invoked any API/Configuration not supported by it.
  example: Device configuration is not supported in free version of controller.

Known Issues

• Supported value for flows[i].metrics.latency.mode is cut_through.
• The metric loss in flow metrics is currently not supported.
• When flow transmit is started, transmission will be restarted on any existing flows already transmitting packets.
