ATM
Several commands are available to display specific Asynchronous Transfer Mode
(ATM) statistics:
:atm debug aal5stats
Displays AAL5 port specific Asynchronous Transfer Mode (ATM) statistics
:atm debug gstats
Displays global ATM statistics
:atm debug portstats
Displays port specific ATM statistics
Below some examples are provided:
=>:atm debug aal5stats
port = dsl0
vpi = 8
[vci] = 36
[clear] =
:atm debug aal5stats port=dsl0 vpi=8 vci=36
# of CRC-32 errors = 0.
# of SAR timeouts = 0.
# of too long SDU errors = 0.
# of invalid CPI field = 0.
# of invalid length errors = 0.
# of aborted CPCS-PDUs = 0.
# of out of memory errors = 0.
=>
=>:atm debug gstats
# of received octets = 806130.
# of transmitted octets = 806766.
# of received cells = 15210.
# of transmitted cells = 15222.
# of unknown cells = 0.
# of errors on the input = 0.
# of errors on output = 0.

The SpeedTouch™ supports active Operation and Maintenance (F4/F5 OAM),
LoopBack (LB) and Continuity Checks (CC) statistics via following commands:
:atm oam cc send
Sends CC activate/deactivate to connection.
:atm oam ping
Sends ATM loopback cells
Below an example is provided of an ATM OAM ping:
=>:atm oam ping dest RtPPPoA count 5
loopback: successful, sequence: 1 time: 4702 usec
loopback: successful, sequence: 2 time: 4754 usec
loopback: successful, sequence: 3 time: 5200 usec
loopback: successful, sequence: 4 time: 5130 usec
loopback: successful, sequence: 5 time: 4785 usec
--- loopback statistics ---
5 loopbacks transmitted, 5 successful, 0% loss, time 180 ms
rtt min/avg/max = 4702/4914/5200
