atmdump - capture or generate ATM cells

       Werner Almesberger, EPFL ICA <Werner.Almesberger@epfl.ch>

atmdump  captures  or  generates  single ATM cells ("AAL0"). When capturing cells, a time stamp, the cell
       header contents, and a hex dump of the cell payload are shown. When sending cells, the payload type,  the
       generic flow control (GFC), and the cell loss priority (CLP) can be set.

       In both modes of operation, the interface number, the VPI, and the VCI have to be specified.

       When  sending,  atmdump  expects  the  cell payload on standard input.  If only less than 48 bytes can be
       read, the remaining space is padded with zero bytes.

-i     displays timestamps as the interval since the last cell reception. By default, the  absolute  time
              is displayed. This options is ignored in transmit mode.

       -ttype
              selects  transmit mode and specifies the payload type. A list of valid payload type numbers can be
              obtained by invoking atmdump without any arguments.

       -ggfc specifies the value of the GFC field. gfc has to be in the range from 0 to 15, default is zero.

       -c     sets the cell loss priority flag, indicating low priority. By default, CLP is not set.

       Some device drivers may not pass OAM cells transparently.
