NAME
atmloop - get/set loopback mode of ATM interfaces
SYNOPSIS
atmloop -s [-l level] [-r level] [itf]
atmloop [itf]
atmloop -q [itf]
atmloop -V
DESCRIPTION
atmloop sets or shows the current loopback settings of an ATM interface, and allows to query the loopback modes supported by the interface.
Some ATM cards can be configured to echo data back to the driver (local loopback) or to the network (remote loopback). The echoing may be
done at several different levels:
aal AAL PDUs
atm ATM cells
digital
bits sent to or received from the line interface
analog the analog signal
The levels supported by an interface can be queried with the -q option. If invoked without options, atmloop displays the current loopback
settings.
OPTIONS
-s set loopback mode. Followed by either -l or -r, both options to set local and remote loopback at the same time (if supported by the
driver), or none of them to turn off any loopback.
-l level
enable local loopback.
-r level
enable remote loopback.
-q level
query loopback levels supported by the interface.
-V print version number of atmloop on standard output and exit.
