atmloop

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 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.
