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 OAM
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 debug aal5stats

vpi = 8
[vci] = 36
[clear] =
:atm debug aal5stats port=dsl0 vpi=8 vci=36
