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.
