Release Features(s)

• Ixia Chassis & Appliances(Novus, AresOne): Support added for BGP/BGP+ over ISIS Simulated Topology. More Details

    loopback = simRtr.Ipv4Loopbacks().
                Add().
                SetName("IPv4Loopback").
                SetAddress(dutIPv4).
                SetEthName(simRtr.Ethernets().Items()[0].Name())
    simRtrBgp= simRtr.Bgp().
            SetRouterId(loopback.Address())
    simRtrBgpIntf = simRtrBgp.Ipv4Interfaces().Add().
            SetIpv4Name(loopback.Name())
    simRtrBgpIntf.Peers().Add().
            SetAsNumber(1111).
            SetAsType(gosnappi.BgpV4PeerAsType.EBGP).
            SetPeerAddress(fromPeerIp).
            SetName("BgpPeer1")

  Note: For configuration of simulated topology please refer here.

• Ixia-C, Ixia Chassis & Appliances(Novus, AresOne): Support added for GRE header in traffic flows.

    flow1 := config.Flows().Add()
    ...
    gre := flow1.Packet().Add().Gre()
    ...

  Note: By default the correct GRE Protocol value will be set automatically depending on next header eg. IPv4/v6.

Bug Fix(s)

• Ixia Chassis & Appliances(Novus, AresOne): Issue is fixed where fetching ISIS learned information using get_states would sometimes fail with a error Cannot clear data while transfer is in progress - data would be inconsistent.

• Ixia-C: Issue is fixed where ARP/ND resolution was failing for LAG configurations with a mix of Loopback and connected interfaces.

• Ixia-C: Issue is fixed where on fetching BGP/BGP+ learned prefix information using get_states would return an incorrect prefix in certain scenarios. This was more likely to happen for IPv6 prefixes.

• Ixia-C, UHD400: Issue is fixed where if the DHCPv6 client type is configured as IANAPD, DHCPv6 Server get_states doesn't show IAPD addresses.

• UHD400: Issue is fixed where Auto MAC resolution was not working properly for multinic scenarios such as LAG, resulting in flows being transmitted with dest MAC as 00:00:00:00:00:00 and DUT not forwarding these packets.

Known Issues

• Ixia-C, UHD400: When DHCPv6 Server is configured with multiple pools, The DHCPv6 clients are not accepting addresses from different pools.
• 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.
