SYNOPSIS
|
||||
iperf3 -s [ options ]
|
||||
iperf3 -c server [ options ]
|
||||
|
||||
|
||||
|
||||
|
||||
DESCRIPTION
|
||||
iperf3 is a tool for performing network throughput measurements. It
|
||||
can test TCP, UDP, or SCTP throughput. To perform an iperf3 test the
|
||||
user must establish both a server and a client.
|
||||
|
||||
|
||||
The iperf3 executable contains both client and server functionality.
|
||||
An iperf3 server can be started using either of the -s or --server com-
|
||||
mand-line parameters, for example:
|
||||
|
||||
|
||||
iperf3 -s
|
||||
|
||||
|
||||
iperf3 --server
|
||||
|
||||
|
||||
Note that many iperf3 parameters have both short (-s) and long
|
||||
(--server) forms. In this section we will generally use the short form
|
||||
of command-line flags, unless only the long form of a flag is avail-
|
||||
able.
|
||||
|
||||
|
||||
By default, the iperf3 server listens on TCP port 5201 for connections
|
||||
from an iperf3 client. A custom port can be specified by using the -p
|
||||
flag, for example:
|
||||
|
||||
|
||||
iperf3 -s -p 5002
|
||||
|
||||
|
||||
After the server is started, it will listen for connections from iperf3
|
||||
clients (in other words, the iperf3 program run in client mode). The
|
||||
client mode can be started using the -c command-line option, which also
|
||||
requires a host to which iperf3 should connect. The host can by speci-
|
||||
fied by hostname, IPv4 literal, or IPv6 literal:
|
||||
|
||||
|
||||
iperf3 -c iperf3.example.com
|
||||
|
||||
|
||||
iperf3 -c 192.0.2.1
|
||||
|
||||
|
||||
iperf3 -c 2001:db8::1
|
||||
|
||||
|
||||
If the iperf3 server is running on a non-default TCP port, that port
|
||||
number needs to be specified on the client as well:
|
||||
|
||||
|
||||
iperf3 -c iperf3.example.com -p 5002
|
||||
|
||||
|
||||
The initial TCP connection is used to exchange test parameters, control
|
||||
the start and end of the test, and to exchange test results. This is
|
||||
sometimes referred to as the "control connection". The actual test
|
||||
data is sent over a separate TCP connection, as a separate flow of UDP
|
||||
packets, or as an independent SCTP connection, depending on what proto-
|
||||
col was specified by the client.
|
||||
|
||||
|
||||
Normally, the test data is sent from the client to the server, and mea-
|
||||
sures the upload speed of the client. Measuring the download speed
|
||||
from the server can be done by specifying the -R flag on the client.
|
||||
This causes data to be sent from the server to the client.
|
||||
|
||||
|
||||
iperf3 -c iperf3.example.com -p 5202 -R
|
||||
|
||||
|
||||
Results are displayed on both the client and server. There will be at
|
||||
least one line of output per measurement interval (by default a mea-
|

surement interval lasts for one second, but this can be changed by the

|
||||
process emitting that output (in other words, the output on the client
|
||||
shows the measurement interval data for the client.
|
||||
|
||||
|
||||
At the end of the test is a set of statistics that shows (at least as
|
||||
much as possible) a summary of the test as seen by both the sender and
|
||||
the receiver, with lines tagged accordingly. Recall that by default
|
||||
the client is the sender and the server is the receiver, although as
|
||||
indicated above, use of the -R flag will reverse these roles.
|
||||
|
||||
|
||||
The client can be made to retrieve the server-side output for a given
|
||||
test by specifying the --get-server-output flag.
|
||||
|
||||
|
||||
Either the client or the server can produce its output in a JSON struc-
|
||||
ture, useful for integration with other programs, by passing it the -J
|
||||
flag. Because the contents of the JSON structure are only competely
|
||||
known after the test has finished, no JSON output will be emitted until
|
||||
the end of the test.

used to set the parameters of a test. They are given in the "GENERAL

the server, in milliseconds. The default behavior is the oper-
