#    This sample creates 10 IPv4 interfaces on two ports. Also a stream is     #
#    created in order to transmit from the 10 interfaces on the Tx port to the #
#    10 interfaces created on the Rx port. The Tx and Rx ports must be         #
#    connected to a Cisco DUT with appropriate interface configuration.        #
#                                                                              #
#    Transmision lasts for 5 seconds then statiscs are retrieved. The latency  #
#    control mode is set to store and forward in order to measure the time     #
#    interval between the last data bit out of the Ixia transmit port and the  #
#    first data bit received by the Ixia receive port.                         #
#                                                                              #

#    The sample was tested on a LM1000STXS4 module.                            #
