# Description:                                                                 #
#    This sample configures a PPPoE tunnel with 20 sessions between the        #
#    SRC port and the DUT. Traffic is sent over the tunnel and the DUT sends   #
#    it to the DST port. After that a few statistics are being retrieved.      #
#                                                                              #
# Module:                                                                      #
#    The sample was tested on a LM1000STXS4 module fiber mode.                 #
#                                                                              #
