L2PING(8)		FreeBSD	System Manager's Manual		     L2PING(8)

NAME
     l2ping -- send L2CAP ECHO_REQUEST to remote devices

SYNOPSIS
     l2ping [-fh] -a BD_ADDR [-c count]	[-i delay] [-S BD_ADDR]	[-s size]

DESCRIPTION
     The l2ping	utility	uses L2CAP ECHO_REQUEST	datagram to elicit an L2CAP
     ECHO_RESPONSE from	a remote device.

     The options are as	follows:

     -a	BD_ADDR
	     Address of	remote device to ping.	Example: -a 00:01:02:03:04:05.

     -c	count
	     Number of packets to send.	 If this option	is not specified,
	     l2ping will operate until interrupted.

     -f	     ``Flood'' ping, i.e., no delay between packets.

     -h	     Display usage message and exit.

     -i	wait
	     Wait wait seconds between sending each packet.  The default is to
	     wait for one second between each packet.  This option is ignored
	     if	-f has been specified.

     -S	BD_ADDR
	     Send L2CAP	ECHO_REQUEST from local	device that has	BD_ADDR.
	     Example: -S 00:05:04:03:02:01.

     -s	size
	     Specify the number	of payload bytes to be sent.  The default is
	     64.  The maximum size is 65531.  Use this option with caution.
	     Some implementations may not like large sizes and may hang	or
	     even crash.

BUGS
     Could collect more	statistic.  Could check	for duplicated,	corrupted and
     lost packets.

DIAGNOSTICS
     The l2ping	utility	exits 0	on success, and	>0 if an error occurs.
