#    5. Start Protocol And Retrieve protocol statistics.                       #
#    6. Retrieve protocol learned info in Port1.                               #
#    7. Retrieve protocol learned info in Port2.                               #
#    8. On the fly change SID Index value for IPv4 MS Ranges in Device Group1. #
