atmdiag shows statistic counters maintained by ATM device drivers. If one or more interface numbers are
specified, the statistics of only 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.
RX_drop
number of PDUs dropped because of lack of memory.
