ATMLOOP(8)		     Maintenance Commands		    ATMLOOP(8)

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 inter‐
       face, and allows to query the loopback modes supported  by  the	inter‐
       face.

       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  set‐
       tings.

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.
