# PURPOSE OF THE SCRIPT:
#      To check the Traffic Statistics for ITU-Implementation.
#
# SCRIPT-GEN USED : No
# IXNCFG USED     : config.ituTrafficStats.ixncfg
#                 : configure 1 Bridge, 2 MEP, 2 MIP, single MD level, 2 MAC
#                   ranges, 5 mac count using Single VLAN (TPID 0x8100, default
#                   priority ) on each port and send traffic from Mac ranges.Use
#                   Different MA names.
#
# Sequence of events being carried out by the script
#   1) Load the config file
#   2) Start CFM protocol
#   3) Start Traffic
#   4) Wait for some time for traffic flow
#   5) Stop traffic
#   6) Check Transmitted and Received Frames
#   7) Stop CFM protocol
