these interfaces are shown. Otherwise, statistics of all interfaces are displayed.
The following counters are shown for each AAL:
TX_okay
number of successfully sent PDUs.
TX_err number of PDUs not sent because of errors.
RX_okay
number of successfully received PDUs.
RX_err number of PDUs discarded because of errors.

ATMDUMP(8) Maintenance Commands ATMDUMP(8)NAME
atmdump - capture or generate ATM cells
SYNOPSIS
atmdump [-i] [ -t type [-g gfc] [-c] ] [itf.]vpi.vci
DESCRIPTION
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.
OPTIONS -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.
-t type
selects transmit mode and specifies the payload type. A list of valid payload type numbers can be obtained by invoking atmdump with-
out any arguments.
-g gfc 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.
RESTRICTIONS
Some device drivers may not pass OAM cells transparently.
