NAME
       iperf - perform network throughput tests

SYNOPSIS
       iperf -s	[options]

       iperf -c	server [options]

       iperf -u	-s [options]

       iperf -u	-c server [options]

DESCRIPTION
       iperf is	a tool for performing network throughput measurements.	It can
       test either TCP or UDP throughput.  To perform an iperf test  the  user
       must establish both a server (to	discard	traffic) and a client (to gen-
       erate traffic).

GENERAL	OPTIONS
       -b, --bandwidth
	      set the target bandwidth	and  optional  standard	 devation  per
	      _mean_,[_stdev_] (See NOTES for suffixes)

	      fault 128K, UDP default 1470)

	   --l2checks
	      perform layer 2 length checks on received	UDP packets  (requires
	      systems that support packet sockets, e.g.	Linux)

       -m, --print_mss
	      print TCP	maximum	segment	size (MTU - TCP/IP header)

       -o, --output filename

	      reports

       -y, --reportstyle C|c
	      if set to	C or c report results as CSV (comma separated values)

SERVER SPECIFIC	OPTIONS
       -b, --bandwidth n[kmgKMG]
	      set target read rate to n	bits/sec. TCP only for the server.

       -s, --server
	      run in server mode

	   --udp-histogram[=binwidth[u],bincount,[lowerci],[upperci]]
	      output UDP latency histograms, bin width (default	1 millisecond,
	      append u for microseconds,)  bincount  is	 total	bins  (default

	      bind src ip addr and optional src	device for receiving

       -D, --daemon
	      run the server as	a daemon.  On Windows this will	run the	speci-
	      fied command-line	under the IPerfService,	installing the service
	      if necessary.  Note the service is not configured	to  auto-start
	      or  restart  - if	you need a self-starting service you will need
	      to create	an init	script or use Windows "sc" commands.

       -H, --ssm-host host
	      Set the source host (ip addr) per	SSM multicast, i.e. the	 S  of
	      the S,G

       -R, --remove
	      remove the IPerfService (Windows only).

       -U, --single_udp

	      able loads use format mean,standard deviation

       -c, --client host

	      ing,  in	bytes  or bits per second. Only	available on platforms
	      supporting the SO_MAX_PACING_RATE	socket option. (Note: Here the
	      suffixes	indicate bytes/sec or bits/sec per use of uppercase or
	      lowercase, respectively)

	   --incr-dstip
	      increment	the destination	ip address  when  using	 the  parallel
	      (-P) option

	   --ipg n

	      load  defined  by	mean and standard deviation using a log	normal
	      distribution, defaults to	60:20m,0.  (Note:  Here	 the  suffixes
	      indicate	bytes/sec  or  bits/sec	per use	of uppercase or	lower-
	      case, respectively)

       -n, --num n[kmKM]
	      number of	bytes to transmit (instead of -t)

       -r, --tradeoff
	      Do a bidirectional test individually  -  client-to-server,  fol-
	      lowed by a reversed test,	server-to-client

       -t, --time n
	      time  in	seconds	to listen for new traffic connections, receive

ENVIRONMENT
       Note:  The environment variable option settings haven't been maintained
	      well.  See the source code if these are of interest.

NOTES
       Some  numeric  options  support	format characters per '<value>c' (e.g.
       10M) where the c	format characters are k,m,g,K,M,G.   Lowercase	format
       characters  are 10^3 based and uppercase	are 2^n	based, e.g. 1k = 1000,
       1K = 1024, 1m = 1,000,000 and 1M	= 1,048,576

       The -b option supports variable offered loads through the <mean>,<stan-
       dard  deviation>	format,	e.g. -b	100m,10m on the	client.	 The distribu-
       tion used is log	normal.	 Similar for the isochronous option.

       The -e or --enhanced latency output on  the  UDP	 servers  assumes  the
       clients'	 and  servers'	system	clocks are synchronized.  Network Time
       Protocol	(NTP) or Precision Time	Protocol (PTP) are commonly  used  for
       this.   The  reference  clock(s)	or oscillator's	error will also	affect
       the accuracy of UDP latency measurements.

       The -B option affects the bind()	system call.  This is  typically  used
       to  bind	 to  a particular IP address. Only packets destined to that IP
       address will be received	while any transmitted packets will carry  that
       IP  address as their source. The	bind() does not	control	anything about
       the routing of transmitted packets. So, for example, if the IP  address
       of eth0 is used for -B and the routing table for	the destination	IP ad-
       dress (per -c) resolves the ouput interface to be eth1, then  the  host
       will  send  the	packet	out  device eth1 with the source IP address of
       eth0.  To affect	the physical output interface (e.g.  dual  homed  sys-
       tems) the host's	routing	table(s) need to be configured,	e.g. configure
       policy routing per each -B source address.

       The TCP connect time (or	three way handshake) can be seen on the	 iperf
       client  when  the  -e  (--enhancedreports)  option is set. Look for the
       ct=<value> in the connected message, e.g.in  '[	3]  local  192.168.1.4
       port 48736 connected with 192.168.1.1 port 5001 (ct=1.84	ms)' shows the
       3WHS took 1.84 milliseconds.

       The network power (NetPwr) metric is experimental.  It's	a  convenience
       function	 defined  as throughput/delay.	For TCP, the delay is the sam-
       pled RTT	times.	For UDP	the delay is the end/end latency.  Don't  con-
       fuse  this  with	 the  physics  definition of power (delta energy/delta
       time) but more of a measure of a	desireable property divided by an  un-
       desireable  property.   Also note, one must use -i interval with	TCP to
       get this	as that's what sets the	RTT  sampling  rate.   The  metric  is
       scaled  to  assist  with	human readability.  (Note: if this metric goes
       beyond the experimental state we'll consider a supporting and RTT  sam-
       pling rate independent of the -i	interval.)
