Bug Fix(s)

• Ixia Chassis & Appliances(Novus, AresOne): Issue is fixed where on running a test with a large number of replay_updates multiple times would cause a PCPU out of memory crash, resulting in "context deadline" error on set_config or set_control_state.protocol.start.

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: Non default virtual wiring configuration can result in ARP failures and traffic loss due to dropped packets on the rx path.
• 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.
