    in the form of a protocol tower. Specify either this argument or
    the Name argument.

         address tower-set [,optional argument...]

    Optional arguments are: format, length, count.

    loop loopback application address = {([%x0119], -
         [dna_sessioncontrolv3, number = 25], -
         [dna_nsp], -
         [dna_osinetwork, 49::00-04:AA-00-04-00-1A-10:20])}

    loop loopback application address = {([%x0119], -
         [dna_sessioncontrolv3, number = 25 ], -
         [dna_ositransportV1, %xDEC0 ] , -
